-                    _Hints for Flower Photographers_
-
-
-If your interest in desert flowers includes a desire to obtain beautiful
-photographs of them, the following “tips” may be helpful.
-
-
-MOTION is a major hazard in still photography, and flowers, especially
-those on long, slender stems, seem to be constantly in motion stimulated
-by the ever-present desert breeze. The practical solution to this
-problem is to take your photographing jaunts, if possible, in the early
-morning when the air is most likely to be motionless. A flower picture
-blurred by motion is a complete flop!
-
-Except for motion, nothing will irritate you more often than the abrupt,
-frequent, and marked CHANGES IN LIGHTING due to small clouds passing
-over the sun. Again, early morning has an advantage in normally
-cloudless desert skies. Clouds may be expected after 10 o’clock on many
-days.
-
-
-DEPTH OF FIELD is highly important in flower photography, and you will
-be gratified with the results if you take pains to have all parts of the
-picture, except the background, in sharp focus. This desirable objective
-has become less difficult to attain with the advent of “faster” films
-which enable you to use the required small diaphragm “stop” without too
-greatly reducing the shutter speed, and still obtain adequate exposures.
-
-
-Too many flower photographers fail to get really CLOSE UP PICTURES. A
-single blossom or a small cluster of blossoms provides a much more
-attractive and significant picture than an entire plant. One blossom
-with, perhaps, a bud, one fruit, and a trace of foliage, if well
-composed, is tops among flower pictures. This objective requires camera
-equipment with the ability to focus on objects close to the lens. Also
-it complicates the goal of getting all parts of the picture into sharp
-focus.
-
-
-UNCLUTTERED BACKGROUNDS are a “must” in flower pictures. You might
-consider joining the flower photographers who carry with them plain gray
-or variously tinted background cards or light-weight boards. Such a card
-or board of contrasting color, when placed behind the blossom, will
-accomplish wonders in giving prominence to the flower. One method of
-obtaining a dark background is to ask someone (if you are a
-contortionist you can do it yourself) to stand in such a position as to
-cast a shadow on the ground or foliage behind the subject. The sky makes
-an excellent background, and you will find it useful whenever you can
-set your camera below the level of the subject.
-
-
-With the foregoing points in mind, study the pictures in this booklet
-with the aim of trying to surpass them in quality. By exercising care
-and patience, you should be able to do so.

-
-
-                              _The Desert_
-
-When Webster defined a desert as a “dry, barren region, largely treeless
-and sandy” he was not thinking of the 50,000 square mile Great American
-Desert of the southwestern United States and northern Mexico. Most of it
-is usually dry and parts may be sandy, but as a whole, it is far from
-barren and treeless. Heavily vegetated with gray-green shrubs, small but
-robust trees, pygmy forests of grotesque cactuses and stiff-leaved
-yuccas, and myriads of herbaceous plants, the desert, following rainy
-periods, covers itself with a blanket of delicate, fragrant wildflowers.
-Edmund C. Jaegar, author of several books on deserts, reports that the
-California deserts alone support more than 700 species of flowering
-plants.
-
-The late Dr. Forrest Shreve, for many years Director of the Desert
-Laboratory of the Carnegie Institution near Tucson, Arizona, defined a
-desert as “a region of deficient and uncertain rainfall.” He divided the
-Great American Desert into four major sections: (1) _Chihuahuan_
-(chee-WAH-wahn), including the Mexican States of Chihuahua and Coahuila
-(coa-WHEE-lah), southwestern Texas, and south-central New Mexico; (2)
-_Sonoran_, including Baja California, southwestern Arizona, and
-northwestern Sonora; (3) _Mojave_ (moh-HAH-vee), Colorado, including
-south-eastern California and extreme southern Nevada; (4) _Great Basin_,
-including Nevada, Utah, southwestern Idaho and southeastern Oregon.
-
-Since the steppes and mesas of the Great Basin Desert have generally
-lower temperatures, higher elevations, and greater precipitation than
-the other three sections, we are not including its flowers in this work.
-
-
-                    _Why and When Do Deserts Bloom?_
-
-The Great American Desert produces, when conditions are favorable, a
-gorgeous exhibition of wildflowers. Trees, shrubs, and herbs all
-contribute to the splendor of the display. Soil composition, slope and
-exposure, suitable temperatures, and adequate moisture are essential to
-plant growth and flower production.
-
-Moisture is the uncertain factor, and years may pass without enough
-rainfall to stimulate plant growth. Rain of less than 0.15 inch is
-wasted as far as desert plants are concerned, for the moisture
-evaporates before penetrating the soil. Some annuals produce seeds
-having water-soluble germination inhibitors in their coverings, hence
-fail to sprout, even after rain, unless the moisture totals at least
-half an inch.
-
-When soil moisture from December and January rainfall is enough to
-support potential plants it dissolves the seed coats, and the desert
-floor is soon carpeted with eager green seedlings. When winter rains are
-scant, as is so often the case, the dormant seed population fails to
-germinate and the spring flower display doesn’t appear. There is no sure
-way to forecast a spectacular blossom year, for a sudden cold wave or
-period of drying winds may literally nip in the bud a potential season
-of brilliant bloom. A great flower year may occur only once in a decade.
-
-Perennials are more dependable than annuals, since some of them,
-particularly cactuses and other succulents, have water storage tissues
-in their stems or roots. These perennials may be counted on to blossom
-each year, but with much less abandon than after winters of above normal
-precipitation. Many perennials have surprisingly extensive root systems.
-Fascinating are the ways by which plants manage to thrive under severe
-conditions of desert heat and drought. As we have seen, most annuals lie
-dormant as seeds until suitable moisture and temperature occur. Then
-they grow very rapidly, to bloom and mature seeds while the soil still
-has moisture. Winter rains produce spring-blooming ephemerals, and
-summer showers produce summer “quickies.”
-
-Another group of plants, including the ocotillo (oh-koh-TEE-yoh), slows
-down life processes to become dormant during dry periods, even to
-dropping all leaves. When rains come they put on new leaves, several
-times a year if necessary.
-
-Cactuses and other succulents gorge themselves with water when the soil
-is wet, releasing moisture very sparingly from storage tissues during
-the “long dry.” Some have discarded or reduced foliage, or have covered
-leaf surfaces with varnish or wax, to decrease to a minimum the loss of
-vital moisture through transpiration.
-
-
-                    _Identifying Desert Wildflowers_
-
-Unless you are a botanist, identification of flowers by measuring and
-counting their various parts, as described in technical keys, is
-generally too complicated to be practical. Several years ago,
-recognizing this problem, I authored a book, _Flowers of the Southwest
-Deserts_, illustrated by Jeanne R. Janish and published by the
-Southwestern Monuments Association, designed to aid the wildflower
-fancier in plant identification by color-grouping the flowers. With Mrs.
-Janish’s superb illustrations pointing out each plant’s most obvious
-characteristics, it has proved an excellent field guide. However, the
-demand for natural color flower portraits could not go unheeded, and
-this book is the result. The two books complement each other, although
-each fills a need in its own right. Used together, they make you more
-positive of some identifications.
-
-Probably the best way to become acquainted with a flower is to be
-introduced to it by someone. But there is one catch to this method—one
-plant may be known by many aliases.
-
-When the Spaniards came into the Southwest over 400 years ago they found
-Indians had names for some flowers in their own languages. The Spaniards
-added their names, and later the Americans added English names. Some of
-these names were of similar-appearing but quite different flowers they
-had known “back East.” Later, scientists studied the desert plants, and
-gave them all Latin names.
-
-To assist in standardizing names of desert flowers, this booklet gives
-preference in its headings to scientific and common names found in
-_Arizona Flora_, by Kearney and Peebles, Second Edition, 1960. Common
-names found in _Texas Plants, A Checklist and Ecological Summary_, 1962,
-by F. W. Gould, also have been used. In addition, placed within the
-text, are some of the more widely used common names that we have
-encountered. Tree names, both common and scientific, follow the
-_Checklist of Native and Naturalized Trees of the United States_, by
-Elbert L. Little, Jr., 1953.
-
-There are many desert flowers, some quite common, for which there was
-not space in this booklet. If you wish to broaden your acquaintance to
-include more, we recommend, for added reading publications listed in the
-back.
-
-The author wishes to express here sincere thanks to Mrs. Pauline M.
-Patraw, Santa Fe botanist, for assistance in identifying many of the
-flowers pictured here. For assistance in checking identifications, the
-author is indebted to Miss Barbara Lund, Park Naturalist, National Park
-Service; to Dr. Charles T. Mason, Jr., Curator of the Herbarium,
-University of Arizona Tucson; and to Dr. W. B. McDougall, Curator of
-Botany, Museum of Northern Arizona, Flagstaff.

-
-  When Paloverde trims her golden gown,
-  And Deerhorn dons her filaments of white;
-  When tall Saguaro fits his fragrant crown
-  In preparation for the party night;
-  When bats across the ruby sunset dance,
-  When Ocotillo lights his candle’s flame,
-  When verdure carpets Desert’s wide expanse,
-  Then Spring is in the Southwest once again.
-
-  The linnets in their scarlet vests and caps
-  Are first to answer Spring’s insistent call,
-  While white-crowned sparrows scan their travel maps,
-  Discussing details of the coming ball.
-  Then thrashers practice every morn and eve
-  The songs they’ll sing upon that night of nights,
-  While phainopeplas, in their haste to leave,
-  Dash back and forth in short, impatient flights.
-
-  The desert halls glow bright as time draws near.
-  Each cactus wears her frilled and perfumed dress.
-  Ground squirrels, for this joyous time of year,
-  Sport their best furs. The rabbits do no less.
-  From far and near the desert folk have come
-  To wait their hostess, Spring, who, very soon,
-  Will lift stars o’er the skyline, one by one,
-  And then turn on the glorious, golden moon.

-
-                          1. Longleaf ephedra
-
-
-Commonly called “Mormon tea,” there are many species of ephedra
-(ef-FED-rah) growing throughout the Southwest. This yellow-green,
-stringy-stemmed shrub with tiny, scale-like leaves, is usually 3 to 4
-feet tall, but sometimes reaches a height of 12 feet. Its small,
-fragrant, springtime flowers grow in dense clusters that attract
-insects. Some species provide winter forage for cattle and are said to
-be browsed by bighorn sheep. Pioneers brewed a palatable drink from the
-dried stems. Certain Indian tribes considered the brew a tonic,
-beneficial for treatment of syphilis and other diseases. The drug,
-ephedrine, comes from a Chinese member of this genus.

-                             2. Common reed
-
-
-Somewhat resembling bamboo, carrizo grows in dense thickets in marshes,
-along river banks, and in other wet locations. Largest of the grasses,
-it sometimes attains a height of 12 feet. The large, tassel-like flower
-heads appear from July to October and create a spectacular mass display.
-The horizontal rootstalks interlock, crowding out other plants. A single
-rootstalk may extend 30 feet. The straight, hollow stems served Indians
-as arrowshafts, pipestems, and loom rods. Along the Mexican border the
-leaves are woven into mats and the long, sturdy stems are used as
-screens and in roofing native houses.

-
-                         3. Prairie spiderwort
-
-
-Because of its slender, drooping leaves, this delicate blue-to-violet,
-three-petaled flower might easily be mistaken for a lily. Plants grow
-from 8 to 18 inches high. A perennial, the spiderwort’s thick, succulent
-roots enable it to produce blossoms from April to September. Not
-abundant, it is usually found in moist locations in desert mountain
-ranges at elevations above 2,500 feet. Flowers form in clusters at the
-tip of a plant’s stem, and are pollenized by bumblebees that eat the
-pollen.

-
-                             4. Desertlily
-
-
-Limited in its range to the desertlands of southern California and
-southwestern Arizona, the desertlily or ajo (AH-hoe) resembles a small
-easter lily. During dry seasons the plants do not bloom, but following
-wet winters each deeply-buried bulb sends up a vigorous shoot which may
-be from 6 inches to 2 feet tall, with a bud cluster at its tip. The
-delicately fragrant flowers may appear in late February, with some tardy
-bloomers still in evidence in early May. Bulbs were dug and eaten by
-Indians and, because of their flavor, were called ajo (garlic) by the
-Spanish pioneers. The town of Ajo and a nearby valley and mountain range
-in southwestern Arizona were named for this plant.

-
-                              5. Mariposa
-
-
-Similar in appearance to the segolily, State flower of Utah, weakstem
-mariposa, sometimes called “straggling butterfly lily,” varies in color
-from white to pale purple. The slender stem is not erect, like other
-mariposas, of which there are many species, but wanders over the ground
-or makes its twisting way among the branches of low shrubs. It grows at
-elevations up to 4,000 feet on slopes and benches of mountains of the
-Mojave-Colorado Desert, in the Death Valley area, and in the desert
-mountains of southern Arizona, blossoming during April and May. Indians
-and pioneers ate the bulbs.

-
-
-                           6. Golden mariposa
-
-
-Considered by some botanists as a distinct species, this mariposa or
-“butterfly tulip” is found in the higher mountains of the eastern
-Mojave-Colorado Desert and also in the vicinity of the Painted Desert of
-northern Arizona. Common in Petrified Forest National Park from May to
-July, the bright yellow flowers make an eye-catching display among the
-colorful pieces of petrified wood covering the ground. The bulbs can
-withstand severe cold, but suffer during winters when there is frequent
-freezing and thawing.

-
-
-
-
-                           7. Desert mariposa
-
-
-Brightest of the mariposas, the short-stemmed, flame-like flowers
-usually appear singly, but may occur in patches, producing in April a
-spectacular display visible from a long distance. Plants growing under
-bushes elongate their stems to elevate their blossoms into the sunlight.
-Occasional in the Mojave-Colorado Desert, this species is abundant in
-the foothills of some of southern Arizona’s mountain ranges, exceeding
-even the goldpoppy in the neon-like brilliance of display. _Mariposa_ is
-Spanish for butterfly, and the genus name _calochortus_ is Greek for
-beautiful grass.

-                           8. Soaptree yucca
-
-
-Common throughout the Southwest, the many species of yuccas (YUH-kuhs)
-are of two major groups, the narrow-leaf and the wide-leaf. Called
-“soaptree” because of its height (maximum 30 feet) and the fact that its
-roots contain saponin, soaptree yucca or _palmilla_ (pahm-EE-yah—“little
-palm”) belongs in the narrow-leaf group. From southwestern Arizona
-across southern New Mexico, and from west Texas southward into the
-Mexican states of Chihuahua and Sonora, this spectacular plant blossoms
-in May and June on desert grasslands from 2,000 to 6,000 foot
-elevations. Cattle eat the young flower stalks, and Indians used the
-leaf fibers for making fabrics, basketry, and other items. The yucca is
-the State flower of New Mexico.
-

-
-
-
-
-                             9. Joshua-tree
-
-
-Another of the narrow-leaf yuccas and largest of the genus, the
-joshua-tree is restricted in its range to the Mojave-Colorado Desert, of
-which it is the principal indicator. Blossoms, which do not open as wide
-as those of other species, grow in tight clusters at the tips of the
-branches, appearing in March and April. Joshuas do not blossom every
-year, the interval between flowerings depending upon rainfall and
-temperature. A small night lizard is dependent upon the joshua-tree, at
-least 25 {species of birds find nesting sites in it, and numerous
-insects, spiders, and scorpions live in its dried leaves and fallen
-branches.}
-

-
-
-
-
-                            10. Torrey yucca
-
-
-Unlike the narrow-leaf soaptrees which produce dry, capsular fruits, the
-wide-leaf yuccas bear fleshy fruits which Indians cooked and ate.
-Indians also used the leaf fibers in weaving fabrics. Roots contain
-saponin and the Indians still cut them up and use the pieces for soap,
-especially as a shampoo. The stiff, fleshy leaves with needle-sharp tips
-give the plant the name “Spanish bayonet.” Torrey yucca blooms in April
-in southeastern New Mexico and west Texas, with similar plants, _Yucca
-schottii_ in southern Arizona, and _Yucca schidigera_ in the
-Mojave-Colorado Desert.
-
-  _Yucca torreyi_    Lily Family

-
-
-
-                            11. Giant yucca
-
-
-Massive and thick-stemmed, the locally-named “giant dagger” is
-supposedly limited in its native range in the United States to Brewster
-County, Texas. A colony (_Yucca faxoniana_) resembling this species has
-been reported recently in McKittrick Canyon in the Guadalupe Mountains.
-An extensive forest of these spectacular plants has given the name
-Dagger Flat to a broad valley in the Sierra del Carmen of Big Bend
-National Park. Usually blossoming in April, the massive, white flower
-clusters gracing the crowns of thousands of these majestic yuccas create
-a never-to-be-forgotten spectacle. A small night-flying moth is the
-yuccas’ pollenizing agent and, in return for this essential service,
-lays her eggs in the plants’ ovaries where the young feed on the
-developing seeds.

-
-
-
-
-                             12. Sacahuista
-
-
-Sometimes confused with the yuccas, the several species of “beargrass”
-or “basketgrass” have pliant, grasslike leaves, small flowers, and
-papery fruits. The plumelike blossom panicles open in May and June. The
-plants favor rocky hillsides, and rarely occur on valley floors. Indians
-roasted the tender bud stalks for food, and cattle browse the leaves
-when other vegetation is lacking. Mexicans, in weaving basketry, use the
-entire leaves, which are especially desirable for fashioning basket
-handles.
-

-
-[Illustration: SACAHUISTA]
-
-
-
-
-                               13. Sotol
-
-
-Also likely to be confused with the yuccas, sotol has a basal cluster of
-pliant, ribbonlike leaves edged with hooked thorns, and a tall flower
-stalk bearing at its upper end a dense panicle of small, creamy
-(sometimes brown) flowers. Blossoming in May and June, the maturing
-flower clusters remain attractive throughout the summer. Mexicans split
-the succulent basal crowns and allow the sap to ferment, producing the
-fiery alcoholic beverage, sotol (SOH-tole). Desert-dwelling bighorn
-sheep are said to browse the tough leaves. The stiff leaf bases, when
-pulled from the cluster, form the “desert spoons” sold in some curio
-stores.

-
-
-
-
-                               14. Agave
-
-
-Many species of agaves (ah-GAH-vees) or “century plants” attract
-attention on desert hillsides when they send up their tall blossom
-stalks in June and July. The thick, fleshy, sharp-tipped leaves form a
-basal rosette. Some of the larger species may require 10 to 20 years to
-store enough plant food to produce the sturdy, fast-growing flower
-stalk. After blossoming, the exhausted plant dies. _Agave scabra_, one
-of the spectacular forms, is limited in its range to the Chisos
-Mountains of Big Bend National Park, Texas.

-
-                            15. Parry agave
-
-
-Another of the large “century plants,” Parry agave blooms from June to
-August, producing spectacular displays on hillsides in northern Mexico,
-southern New Mexico, and southern Arizona. Some of the larger agaves are
-called mescal (mess-KAHL) because of a potent alcoholic beverage of that
-name distilled from the fermented sap derived from the bud stalks.
-Tequila (tee-KEEL-ah), the famous native drink of Mexico, also is
-distilled from fermented agave juices, and the beerlike pulque
-(pool-KAY) has a similar derivation. Indians roasted the bud stalks in
-stone-lined pits covered with hot rocks. Some of these pits may still be
-seen.

-                            16. Lechuguilla
-
-
-One of the common plants of the Chihauhuan Desert and considered the
-principal indicator of that region, lechuguilla (lay-chu-GHE-ah) covers
-the ground so densely in some places that it is impossible to walk
-through it. The stiff, erect, needle-tipped, banana-shaped leaves are a
-hazard to man and beast. The flowering stalk, which blossoms in May and
-June, is unbranched and flexible, bending gracefully in the desert
-breeze. Deer and cattle nip off the tender buds. Mexicans weave the
-tough leaf fibers into coarse fabrics; and the roots, called _amole_,
-produce suds when rubbed in water.

-
-                              17. Canaigre
-
-
-This coarse, herbacious perennial is one of the early spring flowers of
-the desert, sometimes blooming along road shoulders and in sandy washes
-in late February and March. Commonly called wild rhubarb, its sap and
-roots are high in tannin content, and its delicately pink fruits are
-more attractive than the blossoms. Indians and Mexicans use the leaves
-for greens. Papago Indians of Arizona roast the leaves and use the roots
-for treating colds and sore throat. This plant is a close relative of
-European dock, several species of which have become naturalized in North
-America.

-                       18. Trailing-four-o’clock
-
-
-Blossoming from April to October, trailing allionia, known in some
-places as “trailing four o’clock” or “windmills,” is a spreading annual
-with small but colorful blossoms on long, trailing stems. The prostrate
-branches are sticky, so are often covered with grains of sand and flecks
-of mica. What appears to be one blossom is actually three flowers,
-giving it the name “pink three-flower.” It is found on dry, sandy
-benches throughout desert regions of the Southwest. Fruits are winged.

-
-
-                            19. Sand-verbena
-
-
-One of the early spring flowers, sand-verbena creates spectacular mass
-displays, sometimes alone, usually intermingling with other colorful
-early bloomers such as bladderpod and sundrops, which grow on road
-shoulders and sandy flats. The flowers are delicately fragrant,
-especially at night. Semi-prostrate in habit, sand-verbena leaves are
-covered with a dense growth of short, soft hairs which retard the loss
-of moisture so essential to desert plants. This annual is common from
-southern California and southern Arizona into Sonora.

-
-                         20. Mexican goldpoppy
-
-
-Closely related to the orange California-poppy, official flower of the
-Golden State, the desert species is a bright yellow annual. Following
-warm, wet winters clusters of these glorious blooms dot the hillsides in
-late February or early March. By April they may cover the slopes with a
-blanket of gold interwoven with the blue threads of lupines and purple

-
-
-Not restricted to a desert habitat, this spiny-leafed perennial is
-widespread on dry soils from Nebraska to Wyoming and from Texas to
-southern California and Mexico. Abundant throughout the summer, the
-flowers may be found, in warm climates, during every month of the year.
-Copious spines and the acrid yellow sap make the plants distasteful to
-cattle, so a heavy growth of pricklepoppy may be an indicator of an
-overgrazed range. Also called “thistlepoppy,” a single plant may be
-graced by a dozen or more fragile flowers, each ready to be replaced by
-one or more prickly buds. The seeds are said to contain a powerful
-narcotic.

-
-
-Also known as “yellow cups,” this plant is limited in its range to the
-Mohave-Colorado Desert. Having smaller blossoms than the goldpoppy with
-which it might be confused, this showy annual blooms March to May in dry
-washes and on stony hills below 4,500 feet. The foot-high plants
-sometimes form massed displays accented by splashes of bright red where
-clumps of beavertail pricklypear mark small, rocky islands, or where
-patches of ocotillos wave their scarlet-tipped wands in the spring
-breeze.

-
-
-Found at elevations above 1,000 feet, spectaclepod is one of the
-long-flowering species blooming from February to October. The large
-flower heads are pleasantly fragrant, and the peculiar, flat, double
-fruits resemble tiny spectacles protruding at right angles to the stem.
-This species is found in the Petrified Forest area of northern Arizona,
-and Hopi Indians are reported to use the plant in treating wounds.
-Another species, California spectaclepod, is often abundant, covering
-sandy flats of the lower deserts. This species blooms from February
-through April and sometimes again in the fall.

-
-
-Another early bloomer, February to May, bladderpod is one of the first
-spring flowers to spread its yellow carpet across the desert flats. The
-small, low-growing plants lift numerous clusters of four-petaled
-flowers, forming an understory of color among the taller herbs. In some
-localities, bladderpods are called “beadpods” because of the spherical
-fruits. The plants afford good forage for cattle. A close relative, with
-white to purple flowers, is found from Texas to Arizona and Mexico,
-starting to blossom in January during warm winters.

-
-
-A showy plant with a large terminal cluster of four-petaled flowers, it
-is frequently called “desert wallflower.” When growing under shrubs it
-often extends its stems 2 feet or more to reach up into the sunshine.
-Usually blossoming in March, some plants may be found blooming at almost
-any time during the summer to as late as September.

-
-
-With mimosa-like leaves and long-stamened flowers growing in clusters,
-false-mesquite, “calliandra,” or “fairy duster” is a small, straggling
-bush, quite Japanesy in appearance, from a few inches to 3 feet high. It
-blossoms from February to May, and is quite common below 5,000 feet from
-west Texas to southern California and northern Mexico. In California it
-is especially abundant along the east side of the Chocolate Mountains.
-During periods of drought the leaves enter a state of continued wilt,
-but revive promptly when rain comes.

-
-
-Also known by such descriptive names as “tear-blanket” and
-“wait-a-minute,” catclaw acacia is one of the notoriously thorny shrubs
-or small slender trees of the rocky hillsides and borders of desert
-washes. Flowers are fragrant and, during the blooming period in May,
-attract many insects, including honey bees, which gather and store
-nectar that makes high quality honey. The stringbean-like fruits turn
-red in late summer and, if abundant, make a spectacular show. These
-fruits were ground into meal and used for food by Arizona and Mexican
-Indians. Thickets of catclaw acacia provide havens of refuge for birds
-and rabbits pursued by hawks or other predators.

-
-
-Armed with long, slender, straight white spines, giving it the name
-“white-thorn,” this pretty flowering shrub is abundant over large areas
-of dry slopes and mesas from Texas to Arizona and Mexico at 2,300 to
-5,000 feet. It is often used as a decorative in landscape plantings
-around buildings. Blossoms are fragrant and sometimes continue from May
-to August; the shrub occasionally blooming again in November. Cattle and
-horses eat the bean-like fruits.

-
-
-Mesquite (mess-KEET) is a many-branched tree 15 to 23 feet tall, which
-flowers from late April to June. It is common bordering desert washes,
-often forming dense thickets. The flowers furnish honey bees and other
-insects with nectar, and the long, sweet pods ripen in autumn, providing
-food for livestock. The fruits have long been a staple in the diet of
-desert Indians, who used the trunks, roots, and branches of the trees
-for firewood and the dried gum-like sap to mend pottery and as a black
-dye. The inner bark provided the Indians with materials for basketry and
-coarse fabrics. Roots of mesquite trees have been reported to penetrate
-to a depth of 50 to 60 feet to tap sources of ground water.

-                               30. Senna
-
-
-Blossoming from April to October, this species is common at elevations
-between 1,000 and 3,000 feet Nevada to New Mexico, Arizona, California,
-and northwestern Mexico. There are fifteen or more other species, many
-of which are found in a desert habitat and range in size from
-low-growing herbs to small shrubs 3-5 feet high. Senna is sometimes
-called “rattlebox” because the nearly ripe seeds rattle in their woody
-pods when the plant is stirred, startling the hiker who immediately
-thinks “rattlesnake!” A closely related species, _leptocarpa_, is noted
-for its foul-smelling foliage.

-
-
-Perhaps the most dependable of spring bloomers, blue palo-verde trees
-cover themselves with masses of yellow blossoms in April and May.
-Usually found alongside desert washes, they mark these ephemeral stream
-courses as paths of gold threading the open desert. During much of the
-year the trees are relatively leafless, the green bark of trunk and
-branches taking over the function of leaves. The word _palo-verde_
-(PAH-low-VEHR-dee) means “green stick” in Spanish, referring to the
-color of the bark.

-
-
-Not a southwestern desert native, this striking shrub, 3 to 10 feet
-high, was introduced from South America and has escaped from cultivation
-to establish itself in parts of the desert where conditions are
-suitable. The blossoms are showy but ill-smelling, and are popular as
-ornamentals about homes, especially in Mexico. The shrub’s principal
-advantage in landscape plantings is its long blossoming period, which
-sometimes lasts from April to September.

-
-
-This is but one of many species of lupine, both annual and perennial,
-common throughout the West at nearly all elevations. Perhaps the most
-publicized is the “Texas” lupine, or “bluebonnet,” hailed by Texans as
-their State flower. Desert species are early bloomers, sometimes
-appearing in protected sandy soils and on highway shoulders in January.
-In favorable seasons masses of these handsome blue to violet blossoms
-color desert hillsides with acres of fragrant bloom. Sometimes growing
-in pure stands, often mixed with a variety of other spring flowers,
-lupines may usually be found blossoming as late as June.

-
-
-Considered one of the more handsome of the desert perennials, the
-“adonis” lupine, as it is known in southern California, is found near
-sandy washes in the high desert. It is especially abundant in Joshua
-Tree National Monument. The name _adonis_ refers to its great beauty.
-The name _lupinus_ is derived from the Latin _lupus_ meaning wolf,
-because these plants were at one time thought to be soil predators.
-Actually, as with other members of the pea family, lupines are able to
-take atmospheric nitrogen and leave it in the ground, thereby increasing
-rather than depleting soil fertility.

-
-
-Better known as “smoketree,” this silvery-gray, seemingly leafless shrub
-grows in and along sandy washes below 1,500 feet, throughout the
-Mojave-Colorado Desert. At a distance it resembles a plume of smoke
-rising from a campfire. Its small but violet to indigo flowers cover it
-with a gorgeous blue blanket in May, making it one of the really
-handsome desert shrubs. It requires ample supplies of water, hence is
-restricted to washes that carry runoff from both winter rains and summer
-downpours. The seeds sprout readily, and the seedlings with their
-well-formed leaves look very unlike their parents. Few seedlings survive
-the hazards of drought or being smothered by sand carried down the
-washes by flash floods following cloudbursts.

-
-
-Noted for its royal purple flowers, this low shrub, less than 3 feet
-high with peculiar zig-zag branches, blossoms from April to June. In
-common with other daleas (day-LEE-ahs) it is usually called “indigobush”
-or “peabush.” It is normally found below 3,000 feet in desert mountain
-ranges from southern Utah through Arizona and southeastern California.
-There are many species of dalea in the desert, all characterized by deep
-blue to indigo and rose-violet flowers, which attract attention by their
-beauty. Indians used the extract from twigs for dyeing basketry.

-
-
-Thriving only in a frost-free climate, this is among the largest and
-most beautiful of desert evergreen trees. It is usually found along
-sandy washes, mingling with mesquites and paloverdes. It is particularly
-susceptible to mistletoe infestation, which has killed or weakened many
-fine trees. Blossoming in May and June, the trees are sometimes laden
-with lavender, wisteria-like flowers. The wood is extremely hard and
-heavy, hence the tree is locally known as “ironwood,” or
-_palo-de-hierro_, in Mexico. Indians ate the seeds and used the wood for
-tool handles and arrow-points. Its long-burning qualities made it
-especially desirable for fuel. As a result, many of the trees have been
-cut, making it one of the species threatened with extinction.

-
-
-Many species of “locoweed” ranging in color from deep purple to creamy
-white are found throughout the desert at nearly all elevations. They
-sometimes create extensive mass displays but are more commonly found
-mixed with other flowers. Species with bladder-like pods are called
-“rattleweed.” Loco in Spanish means “crazy” and refers to the fact that
-a number of species of _astragalus_ contain selenium, which causes a
-serious disease among livestock, especially horses, that eat it and as a
-result “act crazy.”

-
-
-Also called “alfileria,” this species and its close relative, Texas
-filaree (_Erodium texanum_) are both early blossoming annuals, often
-widespread on plains and mesas, February to May. The flowers, although
-abundant, are small and so hidden in low-growing foliage that they
-rarely create a mass display. Texas filaree is native to North America,
-but alfileria is thought to have come from Europe with the Spaniards,
-and is now naturalized throughout the Southwest. Corkscrew-like
-appendages of the fruits are tightly twisted when dry, but untwist when
-moist, literally screwing the sharp-pointed fruits into the soil. Both
-species are excellent spring forage for livestock.

-
-
-Often erroneously called “greasewood,” creosotebush is generally
-recognized as the most adaptable of all desert plants, and a definite
-indicator of the Lower Sonoran Life Zone. The shrubs cover thousands of
-square miles, often in pure stands, and flower throughout much of the
-year, but most profusely in April and May. Fuzzy white, globular fruits
-are almost as spectacular as the flowers. The plant can endure long
-periods of drought. Following rains its foliage gives off a musty,
-resinous odor, suggestive of creosote, stimulating the Mexican name
-_hediondilla_ (little stinker). In Mexico the plant is considered to
-have medicinal values and many uses. The Pima Indians boiled the leaves,
-using the decoction as an emetic and to poultice sores. They used the
-lac, found as an incrustation on the branches, to cement arrow-points
-and to mend pottery.

-
-
-Often abundant on road shoulders and in low spots where rainwater from
-hot-weather showers provides adequate moisture, “caltrop” or
-“summerpoppy,” with large blossoms and attractive compound leaves,
-decorates the desert when other flowers are noticeable by their absence.
-The long, weak stems, usually prostrate, give the plants a vine-like
-appearance, but when growing under shrubs they extend upward so that the
-shrub is mistakenly thought to be blooming. Superficially resembling the
-springtime goldpoppy, Arizona-poppy has five rather than four petals,
-and may be found in bloom as late as October.

-
-
-Ranging in size from delicate 6-inch annuals to coarse, woody perennials
-4 feet high, the globemallows vary in color from creamy white to pink,
-rose, peach, and lavender. Desert-mallows flaunt their graceful,
-blossom-covered stems along roadsides or on the banks of sandy washes.
-Because some people are allergic to them, globemallows are called
-“sore-eye poppies” in parts of southern Arizona, and in Lower California
-are known as _plantas muy malas_ (very bad plants).

-
-
-Sometimes confused with tamarack because of the similarity of names,
-five-stamen tamarisk, locally called “salt-cedar,” is one of several
-small tree species from southeastern Europe and western Asia which have
-become naturalized in North America. “Salt-cedar” often forms dense
-thickets on alkaline soils along stream and reservoir banks at
-elevations below 5,000 feet. Flowers, which vary in hue from deep pink
-to white, cover the trees with graceful plumes of color from March to
-August. Although valuable in retarding soil erosion, tamarisk requires
-large quantities of water, an especially undesirable characteristic in
-the arid Southwest.

-
-
-Many species of _mentzelia_, all herbs, occur in the West. Barbed hairs
-cover leaves and stems, causing the plant to cling to what it touches,
-hence a common name “stick-leaf.” Flowers grow at ends of branches, and
-some species open fully only in sunlight. A close relative, _Mentzelia
-involucrata_, “sand blazing-star,” is an annual, 4 to 16 inches high,
-blooming February through April, found in sandy washes below 3,000 feet
-in southwestern Arizona, southeastern California, and northern Sonora.
-_Pumila_ grows in dry stream beds and on roadsides from 100 to 8,000
-feet elevation, flowering February to October. It ranges from Wyoming
-and Utah to southeastern California and Northern Mexico.

-
-
-Also called “stingbush,” this low, rounded bush is usually found growing
-from crevices in cliffs. When covered with large blossoms from April to
-September the plant has a striking appearance. The pale green leaves are
-covered with stinging hairs, strong enough to impale such small
-creatures as bats emerging from cave entrances where they grow.
-Rock-nettle is common in desert ranges of southeastern California,
-especially in the Death Valley area, to western Arizona and southern
-Nevada.

-
-
-Easily overlooked, when not in blossom, as a group of slender, fluted,
-gray-green stems hidden beneath a shrub, this cactus is truly a glorious
-thing when in flower. Beauty and fragrance of its blossoms have earned
-it the name, in Mexico, of _reina-de-la-noche_, meaning
-“queen-of-the-night.”
-
-Buds unfold soon after sunset in late June or early July, perfuming the
-desert air and attracting night-flying insects. They wilt soon after
-sunrise the following morning. The large, tuberous root, which serves as
-a water-storage organ, usually weighs from 5 to 15 pounds, but specimens
-have been found weighing more than 80 pounds. Indians at one time dug
-the tubers for food. The bulbous fruits become red when mature, and are
-almost as spectacular as the flowers. This species is found from west
-Texas to western Arizona and northern Mexico.

-
-
-Largest of the cactuses in the United States, the saguaro (suh-WAR-oh)
-is limited in its principal range to southern Arizona and northern
-Mexico. Although rarely exceeding 30 feet in height, specimens 50 feet
-tall and weighing up to 10 tons, are on record. Blossoms form as huge
-bud clusters at the branch tips, opening a few at a time each night,
-usually in May, and remain open until mid-afternoon of the following
-day. Fruits of the saguaro are eaten by birds and other animals, and at
-one time were important in the diet of desert Indians. The state flower
-of Arizona and the subject of a US. postage stamp issued in February
-1962 to commemorate the 50th anniversary of Arizona’s statehood, the
-saguaro is also commemorated and protected in the National Monument of
-that name near Tucson.

-
-
-Limited in its range to northwestern Mexico and the vicinity of Organ
-Pipe Cactus National Monument in southwestern Arizona, this columnar
-cactus grows in clumps of spine-covered stems, some of which may be 10
-to 15 feet in height, rarely branching, and with no central trunk.
-Blossoms open at or near the stem ends during May nights, and close the
-following day. The spine-covered fruits, about the size and shape of a
-hen’s egg, have long been harvested by the Papago Indians, who boil the
-sweet juice to the consistency of syrup and store the pulp and seeds for
-winter food. The fruits are locally called _pitahaya dulce_, or sweet
-cactus fruit.

-
-
-Not only are there many species of _Echinocereus_, popularly called the
-“hedgehog cactuses,” but there are also several varieties of
-_Echinocereus triglochidiatus_. One variety sometimes develops into
-cushion-like mounds composed of several hundred oblong stems huddled
-together with a seemingly precarious foothold in crevices among the
-rocks or on rocky slopes of the Mojave desert. Another grows in loose
-clusters of cylindrical stems in the higher desert grasslands up to the
-oak belt in the mountains of southern New Mexico, Arizona, and northern
-Mexico. When blossoming in May and June these clustering “hedgehogs”
-create a spectacular display.

-
-
-One of the more common species of “hedgehog,” sometimes called
-“Engelmann echinocereus,” the strawberry echinocereus grows as 2 to 12
-or more robust, cylindrical stems up to a foot in height, among the
-creosote bushes and bur-sages of the Sonoran and Mojave-Colorado
-Deserts, flowering from February to May. Flowers close at night and
-reopen the following morning. Blossoms vary considerably in color from
-purple to lavender. Spines, too, are variable, from gray and yellow to
-dark brown. In southeastern California, where it is common, this species
-is called “calico cactus” because of its many-colored spines. Fruits of
-some varieties (of which there are many) are edible, forming an
-important item in the diet of birds and rodents.

-
-
-Far from common but among the more beautiful of the “hedgehogs” is the
-rainbow echinocereus, also called “rainbow cactus,” so named because of
-the horizontal bands of alternating red and white spines encircling the
-single, sturdy stem. It grows in rocky situations in the mountains of
-southern Arizona and northern Mexico, blossoming from June to August.
-The large flowers, of which there may be from one to four crowding
-around the crown of the plant, are often larger than the plant itself.
-Spines are small and lie densely flat over the somewhat fluted stem,
-which is from 3 to 14 inches high.

-Sometimes called “Texas golden rainbow,” the yellow pitaya of the
-Chihuahuan Desert is similar in appearance, except for the color of its
-blossoms, to the rainbow echinocereus. Quite common in portions of Big
-Bend National Park, the Stubby, upright stems usually grow singly but
-sometimes occur in small clusters. The term _pitaya_ or _pitahaya_ is
-commonly applied along the Mexican border to cactuses bearing edible
-fruits. In Texas the term refers to the low-growing floral hedgehogs; in
-Arizona to the columnar cactuses. Pricklypear cactuses having soft,
-juicy, edible fruit are known as _tunas_.

-
-
-Massive, cylindrical, and covered with clusters of stout spines, the
-central one hook-shaped, these desert giants are often mistaken for
-young saguaros. There are several species, all locally called
-_bisnagas_, with some quite small and others attaining a height of 5 or
-6 feet. The majority produce clusters of orange to red flowers on their
-crowns in late summer, but the yellow-flowered California barrel cactus
-blossoms in the spring. Their tendency to lean toward the light causes
-many of these heavy-bodied plants to tip in a southwesterly direction,
-giving them the name “compass cactus.” This group is naively believed by
-some people to contain water. Actually the slimy, alkaline sap obtained
-by mashing the pulpy flesh might conceivably save someone lost in the
-desert from dying of thirst. The pale yellow fruits are not spiney, and
-are eaten by birds, rodents, deer, and other desert animals.

-
-
-There are a number of species of the low-growing, usually dome-shaped
-mammillarias, the solitary kinds often so small as to be overlooked
-except when blooming, in late spring or early summer. Some are known as
-“fishhook cactuses” because of their long, slender, hooked spines,
-others as “pin-cushion cactuses” because of the shape of the plants. The
-large, colorful blossoms which encircle the stems mature usually to red,
-in some species green, nipple-shaped fruits. Members of this genus are
-widespread in grasslands or rocky mesas and slopes throughout the
-Southwest.

-
-
-Limited in its principal range to the Mojave-Colorado Desert, the
-beavertail is a low-growing species with flat joint-pads and
-bluish-green stems without spines. In their place are clusters of
-brownish spicules set in slight depressions in the wrinkled pads. The
-plants blossom in March and April, adding materially to the color of the
-spring flower display. The plants thrive in sandy desert soils, at
-elevations from 200 to 3,000 feet above sea level, and are found as far
-east in Arizona as Wickenburg. Cahuilla Indians cook the fruits with
-meat, and Panamint Indians dry the pads and boil them with salt.

-
-
-Most widely distributed of the pricklypears, Engelmann plants are large
-and spreading, sometimes forming spiney bushes 3 to 5 feet high and up
-to 15 feet in diameter. The branching stems may have from 5 to 12
-pad-joints. Flowering in April and May, the petals at first are yellow
-but turn to pink or rose with age. The plants prefer washes and benches
-in the desert grasslands, often growing with paloverdes, saguaros,
-mesquites, and lechuguilla agaves. Excessive abundance often indicates
-an overgrazed range. Fruits, called _tunas_, are purple to mahogany when
-mature, and are eaten by many birds and rodents, as well as by desert
-Indians.

-
-
-Also known as “silver cholla” (CHOY-AH) and “teddybear cactus,” this
-stocky bush cactus, with a short sturdy trunk and compact, densely
-spined crown, is common on hot rocky, south-facing hillsides. Joints are
-extremely brittle and the barbed spines catch so easily in the hair of
-animals or clothing of persons that the joints appear to jump from the
-plant. Joints broken off by the wind fall to the ground and take root in
-the sandy soil, gradually developing forests of this striking cactus,
-easily recognized by the silvery sheen of the spines. The attractive
-flowers which appear from March to May blend inconspicuously with the
-spiney joints.

-
-
-Common along banks of washes and on desert flats, this cholla, also
-called “tesajo,” or “Christmas cholla,” is so slender-stemmed and
-sprawling in growth habit that it is easily overlooked in a tangle of
-vegetation. Its flowers, appearing in May and June, are small and
-inconspicuous, but the orange to scarlet fruits about the size and shape
-of olives, are striking eye-catchers in the fall and winter months. In
-the open the shrubby plants are rarely more than 2 feet high, but in
-thickets of northern Mexico some have become almost vinelike, growing up
-through mesquite or paloverde trees to a height of 12 feet or more. The
-species grows at elevations of 200 to 5,000 feet from Texas to western
-Arizona and northern Mexico.

-
-
-This low-growing cholla of the higher desert above 3,500 feet, is
-characteristic of the plateau grasslands, forming mats of short but
-erect stems usually less than 2 feet high. It blossoms in June and July.
-The tender young stems and yellow, fleshy fruits are browsed by
-pronghorns, and the fruits are also used by the Hopi Indians for food
-and as a seasoning. Because of its customary low-growing habit it is
-something of a hazard to hikers. It is considered the most widely
-distributed cholla in Arizona.

-
-
-Flowering in May and June and common throughout southwestern New Mexico,
-southern Arizona, and northern Mexico, the walkingstick cholla is best
-known because of its persistent clusters of yellow fruits. These remain
-throughout the winter, giving persons the first-glance impression that
-the large shrubby cactus, sometimes 8 feet high, is in bloom. The fruits
-are eaten by cattle. This species is typical of desert grasslands and is
-most abundant in the open country below the edge of the oak belt in
-desert mountains. Stems of the dead plants leave a hollow cylinder of
-attractive wooden meshes when the soft tissues decay, and are favored
-for making canes, as the stem is long and straight, hence the name
-walkingstick cholla.

-
-
-Also called “sun-drops,” these plants are particularly welcome because
-they bloom early in the springtime. Many species of evening-primrose are
-large flowered, abundant along roadsides and sandy flats, and notably
-fragrant. White-flowered species are more common, but there are several
-with yellow flowers. Blossoms open at night and begin to wilt, turning
-pink during the following day. These are among the handsomest of desert
-plants and during favorable years make a spectacular spring display,
-sometimes growing with goldpoppies and sandverbenas to produce a riot of
-color.

-
-
-Common to all of the deserts crossed by the boundary between the United
-States and Mexico, ocotillo (oh-koh-TEE-yoh) is a spectacular shrub, its
-many long, stiff, green-barked and thorn-guarded stems bearing at their
-tips clusters of bright red flowers from April to June. Following rains,
-the stems cover themselves with clusters of bright green leaves. When
-drought comes these leaves are shed, to be renewed again after another
-rain. This procedure may be repeated half a dozen times in one year.
-Cahuilla Indians eat both flowers and seeds, and make a beverage by
-soaking the blossoms in water. When planted as hedgerows the thorny
-wands make an impenetrable fence.

-
-
-Also known as “wild morning glory,” this naturalized perennial has
-become a serious agricultural pest throughout the Southwest. In
-California it is considered the State’s worst weed. Once established,
-its deep root system spreads widely, sending up shoots that grow rapidly
-with climbing, vine-like stems and morning glory-like white to pink
-flowers that bloom from May to July. In the desert it is usually found
-on road shoulders, where it makes an attractive display. The name
-_convolvulus_ comes from the Latin and means “to entwine.” A
-blood-clotting substance has been found in this plant.

-
-
-Usually found in desert mountain ranges, at elevations between 5,000 and
-6,000 feet, this ground-hugging, herbaceous perennial blossoms in May
-and June. Flowers are larger than those of the several other desert
-species of phlox, most of which have longer flower stems and vary in
-color from white to purple.

-
-
-More commonly known as “gilia” in honor of the eighteenth-century
-Italian botanist Felippo Luigo Gilii, the many species of gilias are
-common and widespread throughout the deserts of the Southwest at nearly
-all elevations. Since the flowers are usually small and range in color
-from white to lavender, pink, and yellow, they are not as well known as
-more spectacular genera. Some are annuals but there are also many
-perennial species. Starflower is found from west Texas and Chihuahua to
-western Arizona at elevations from 1,000 to 8,000 feet on dry plains and
-mesas, especially on limestone soils. It blossoms from March to October.

-
-
-Known also as “scorpionweed” and “wild heliotrope,” phacelia is a
-handsome plant with coarse foliage, somewhat hairy and sticky. Among
-other plants it often grows to a height of 18 inches, but on dry, open
-desert flats is usually much shorter. Flowers, which may be found from
-February to June, are sweet scented, but the foliage has a disagreeable
-odor. _Crenulata_, which is one of many species, grows from New Mexico
-and southern Utah throughout Arizona to Lower California. It is
-conspicuous among the spring-blooming flowers of the desert. The curling
-flower heads which bear some resemblance to the erect tail of a scorpion
-are responsible for the name “scorpionweed.”

-
-
-In favorable years these ground-hugging plants form broad, colorful
-mats, but in dry seasons these annuals may be tiny, each with a single
-flower almost as large as the rest of the plant. Flowering from February
-to May, bloom is heaviest in March and April. This species, also called
-“purplemat,” is common on flat, sandy, open desert soils from
-southeastern California and Baja California to southeastern Arizona at
-elevations below 3,500 feet. Because of its low-growing habit, nama
-requires that you lie prone to examine it closely, hence is one of the
-many small desert herbs called “bellyflowers.”

-
-
-Believed to be the original host of the Colorado potato beetle, this
-annual is a pest on rangelands because of its spine-covered stems and
-fruits. Spines are long, straight, sharp, and straw-colored. It is
-common on desert plains and mesas at elevations from 1,000 up to 7,000
-feet, blooming from June to August. The leaves and unripe fruits of this
-and several other species are reportedly poisonous, as they contain an
-alkaloid, solanin.

-
-Also known as “white horse-nettle,” “bull-nettle” and “trompillo,”
-silverleaf nightshade is a showy plant when in blossom May to October
-along roadsides and in open fields at elevations from 1,000 to 5,500
-feet from Kansas and Colorado to Arizona, California, and south to
-tropical America. It is an agricultural pest in irrigated areas,
-difficult to eradicate. Pima Indians used the crushed fruits as an
-additive to milk in making cheese. A close relative, _Solanum jamesii_
-is known as wild-potato as it produces small tubers eaten by desert
-Indians.

-
-
-One of the really striking flowers of the deserts and mesas, the large,
-showy, trumpet-shaped blossoms and broad, dark green leaves of the
-datura or “western jimson” arouse the curiosity of persons seeing them
-for the first time. Quite common along roadsides below 6,000 feet from
-California to Texas and Mexico, the white blossoms remain open at night
-but close and droop soon after sunrise. The summer-blooming plants often
-grow in large clumps with buds, flowers, and maturing fruits all present
-at the same time. Indians used the plants for various medicinal
-purposes, a dangerous practice, since all parts of the plant contain
-various alkaloids, including atropine. Roots are narcotic and were
-sometimes eaten by Indians to induce visions.

-
-
-Sometimes growing to a height of 10 or 12 feet, the graceful swaying
-branches of tree tobacco bear at their ends clusters of tubular,
-greenish-yellow blossoms 2 to 3 inches long. The leaves contain the
-alkaloid anabasine, which is poisonous to livestock. Leaves of the
-closely related and much smaller desert tobacco, _Nicotiana
-trigonophylla_, contain nicotine and have long been smoked by desert
-Indians. The plant is still so used on ceremonial occasions. _Nicotiana_
-was named for Jean Nicot, French ambassador to Portugal, who introduced
-tobacco to France about 1560.

-
-
-Although restricted in its range to the Chihuahuan Desert, ceniza,
-sometimes called silverleaf, is so spectacular when in blossom that it
-invariably attracts attention and arouses interest. The small, abundant,
-ash-gray leaves give this 3- to 4-foot shrub a distinguished appearance
-throughout the year, but when it suddenly bursts into bloom, usually in
-September, it becomes a thing of rare beauty. It is so sensitive to
-moisture that it may blossom a few hours after a soaking rain, which
-gives rise to the popular belief that it can forecast wet weather and in
-consequence it is sometimes called “barometer bush.”

-
-
-Penstemons, or “beard-tongues,” of various species are numerous on the
-desert as well as throughout the higher, moister parts of the Southwest.
-This one blooms in spring and early summer below 6,000 feet from
-southwestern New Mexico to southern California. It, and the similar
-Parry Penstemon, are among the more noticeable desert species because of
-their showy flowers covering the clumps of erect stems two to four feet
-tall. Both are fairly common on mesa slopes and mountain canyons with
-individuals well scattered, hence not contributing to the mass flower
-displays of the desert springtime.

-
-
-Known in southern California as “scented penstemon” because of its
-fragrance, this regal “beardtongue” comes to the height of bloom in May.
-However, it may be found in flower from March to September. When the
-tall, flower-covered stems grow in abundance, as often occurs in
-gravelly washes at elevations between 3,500 and 6,500 feet, the sight is
-remarkable. This species prefers limestone soils in both the
-Mojave-Colorado and Sonoran Deserts. The sweet nectar attracts bees.

-
-
-Paintedcups, or “Indian paintbrushes” as they are more widely known, are
-found from desert lowlands to snow-capped mountain tops. _Castilleja
-linariaefolia_ is the State flower of Wyoming. The northwestern
-paintbrush, known in southern California as “desert paintbrush,” has an
-extremely wide range. The flash of red among other desert plants is
-actually due to the brightly colored floral bracts, as the flowers
-themselves are small and inconspicuous. This species blossoms in early
-spring in rocky or gravelly locations between 2,000 and 7,000 feet, on
-dry plains and hillsides.

-
-
-Owl-clover is one of the short-stemmed desert spring annuals which, in
-favorable seasons, carpet the desert floor with a beautiful, colorful
-mass display. Sometimes growing in pure stands, at others mixed with
-goldpoppies, lupines, or other spring flowers, it is found throughout
-southern Arizona, southern California, and Baja California, at
-elevations between 1,500 and 4,500 feet, blossoming from March to May.
-Cattle and sheep graze it extensively. The Spanish name _escobita_ means
-“little broom.” Individual flowers are not conspicuous, but their
-clusters intermixed with the colorful bracts produce a pretty, feathery
-effect.

-
-
-More properly called “desert catalpa,” this tall shrub or small tree, 6
-to 15 feet high, has willow-like leaves, spreading branches, and a
-short, crooked, black-barked trunk. The violet-scented flowers usually
-appear from April to August, often after the start of summer rains. They
-are replaced by long, slender seed pods that remain dangling from the
-branches for months. Mexicans make from the dried flowers a tea that
-they believe has considerable medicinal value. Desert-willow is usually
-found along desert washes below 4,000 feet from west Texas to southern
-California and northern Mexico. It is frequently cultivated as an
-ornamental because of its attractive orchid-like flowers.

-A glossy-leafed shrub with golden, trumpet-shaped flowers, the
-trumpet-bush blooms from May to October on dry, rocky hillsides between
-elevations of 3,000 and 5,000 feet. It is not common, but occurs from
-western Texas through southern New Mexico and Arizona southward into
-tropical America. Trumpet-bush is cultivated as an ornamental in
-southern parts of the United States and in Mexico. The roots are used
-medicinally and in making a beverage. Stems and leaves contain small
-quantities of rubber. The shrubs, which occasionally reach a height of 6
-feet, are browsed by bighorn sheep and probably by deer.

-
-
-Lacking chlorophyll and parasitic on the roots of bur-sage and other
-desert composites, broomrape is so unusual in appearance as to attract
-immediate attention. Although fairly common in low-elevation deserts
-from west Texas and Mexico to southern California, it is occasionally
-found as far north as southern Utah and Nevada and at elevations up to
-7,000 feet. The rather inconspicuous flowers appear from February to
-September. Navajo Indians made a decoction of the plant as a treatment
-for sores. Desert Indians ate the tender stems in springtime.

-
-
-Restricted to western Arizona, southern California, and Lower
-California, _palmata_ has similar-appearing relatives with much wider
-distribution. Their large leaves and vine-like growth attract attention
-along roadsides at elevations up to 7,000 feet. Most widespread of these
-strikingly coarse perennials is _Cucurbita foetidissima_, the
-buffalo-gourd or calabazilla. This rank-growing, ill-smelling vine-like
-plant may have prostrate stems up to 20 feet long. The globular fruits,
-of tennis ball size, were cooked by Indians or dried for winter
-consumption. Seeds were boiled to form a pasty mush. California pioneers
-used the crushed roots as a cleansing agent in washing clothes, but
-found that particles clinging to the cloth were a skin irritant.

-
-
-Common throughout the Southwest, particularly on overgrazed rangelands
-and deserted clearings, this plant, also called “matchweed” or
-“turpentine-weed,” often occurs in almost pure stands. The resinous
-stems burn readily, throwing off black smoke. Most abundant on dry hills
-and mesas, 3,000 to 6,000 feet elevation, this perennial is found from
-1,000 to 7,000 feet, blossoming from June to October. Bees obtain nectar
-and pollen from the small but densely crowded, yellow flower clusters.
-The many stiff, upright branches cause some plants to appear almost
-globular in shape and a foot to 2 feet in diameter. Plants of this genus
-are reported as poisonous to sheep and goats if eaten in quantity, but
-are apparently unpalatable, as they are rarely grazed.

-
-
-Also known as “desert daisy” and “rock daisy,” this dwarf winter annual
-grows on sandy or stony mesas at elevations below 3,500 feet, blossoming
-from February through April. The short stems spread to form a mat or
-rosette, 5 or 6 inches across, growing flat on the sand, and ornamented
-with many small flowers, each set off by a small cluster of leaves.
-Desertstar grows principally in southern Arizona and southern
-California, but has been recorded from southern Utah and Sonora, Mexico.

-
-
-Varying in color from violet and lavender to almost white, flower heads
-of the Mohave aster are numerous, sometimes as many as 20 simultaneously
-in bloom on one plant. This ornamental perennial prefers dry, rocky
-slopes below 6,000 feet in southern Utah, Nevada, western Arizona, and
-southeastern California. Characterized by silvery foliage and large
-flower heads, the Mohave aster is well worthy of cultivation and does
-well in hot, dry locations. Flowers appear from March to May, but with
-the coming of summer heat the stems and leaves become twisted, brown,
-and unattractive.

-
-
-By no means limited to the deserts, fleabane is common throughout the
-Southwest, including parts of Mexico. In some localities it is known as
-“wild-daisy.” Six to 15 inches tall, with attractive circular flowers,
-fleabane often forms noticeable patches along road shoulders and on dry
-open slopes, blossoming from February to October. Flowers may be an inch
-in diameter in springtime, but those in summer are usually smaller. The
-name arises from an ancient belief that the odor of some species
-repelled fleas.

-Locally called “desert-broom,” or “Mexican broom,” this species of
-baccharis is an erect, coarse, evergreen shrub 3 to 6 feet high,
-frequently encountered on hillsides and bottomlands at elevations
-between 1,000 and 5,500 feet from southwestern New Mexico to southern
-and Baja California and northern Mexico. Greening up following summer
-rains, the shrubs blossom from September to February. Flowers are
-inconspicuous, but the fruits develop as masses of spectacular cottony
-threads, giving the shrubs a snow-covered appearance. Among some Indian
-tribes the twigs are chewed to relieve toothache. In Mexico the shrub is
-called _hierba del pasmo_.

-stiff, dull green leaves and attractive, four-petaled flowers that are
-present from April to October. Preferring clayey or rocky, arid soils at
-elevations 2,500 to 5,000 feet, this species is found from west Texas to
-southern Arizona and Mexico. Although related to the garden zinnia,
-which is a native of Mexico, only the large flowered desert species,
-_Zinnia grandiflora_, is considered worthy of cultivation.

-
-
-Sometimes blossoming as early as November and often lingering until May,
-brittle-bush is a dome-shaped, winter-flowering bush that brings delight
-to desert dwellers in Nevada, Arizona, southern California, and
-northwestern Mexico. Stems of the low-growing, silvery-leaved shrub
-exude a gum which was chewed by desert Indians and burned as incense by
-priests in mission churches, giving the plant the local name,
-_incienso_. Strictly a desert shrub, about 3 feet high, brittle-bush
-prefers rocky hillsides below 3,000 feet. Growing in masses it often
-covers entire slopes with a mass of golden bloom, contributing to the
-early spring flower display. Bighorn sheep are reported to rely on this
-species for browse.

-
-
-Restricted in its range to the region in which Utah, Arizona, and Nevada
-meet, the “giant sunray,” as it is sometimes called, is spectacular
-rather than beautiful. Coarse and weedy, the large clusters of silvery
-leaves and long stemmed, sunflower-like blossoms that appear from April
-to June invariably attract attention and stimulate curiosity. An even
-larger species, _Enceliopsis covillei_, with blossoms up to 6 inches in
-diameter, is found in canyons on the west side of the Panamint Mountains
-in California.

-
-
-Although it is reported from elevations up to 7,000 feet, golden
-crown-beard is usually found at much lower levels from Kansas south to
-Texas, California, and northern Mexico. Sometimes growing in clusters,
-single plants are also common as a weed of roadsides and waste ground.
-The all-yellow, sunflower-like blossoms are widespread in the desert
-from April to November. Desert Indians and early pioneers are said to
-have used the plant to treat boils and skin diseases. The Hopis soaked
-the plants in water in which they bathed, to relieve the pain of insect
-bites.

-
-
-Also called “tickseed,” wild coreopsis is closely related to cultivated
-ornamentals of the same name. The desert species inhabits open locations
-at elevations between 1,500 and 2,500 feet in southern Arizona, southern
-California, and Baja California. Plants usually bloom between February
-and May. The closely related _Coreopsis bigelovii_ is a southern
-California annual having somewhat larger flowers, up to 2 inches in
-diameter, with orange centers. Flower stems are naked, with the leaves
-clustered at their bases.

-                            91. Paperflower
-
-
-At its best in sandy desert soil, paperflower is a compact, shrubby
-plant about 1 foot high, with tangled branches. When fully developed it
-is symmetrically globular in outline. It prefers mesas and desert plains
-at elevations between 2,000 and 5,000 feet from western New Mexico to
-southern California and northern Mexico, flowering throughout the year
-but most abundantly in springtime. Sometimes called “paper-daisy,” the
-flowers are persistent, fading to straw color and turning papery with
-age. They may remain on the stems for weeks.

-                           92. Desert baileya
-
-
-Commonly called “desert marigold,” baileya blossoms in all seasons, most
-heavily from March to November, and is one of the better known flowers
-of the Southwest. Each circular blossom occupies the tip of a foot-high
-stem. Plants usually have a thrifty, garden-variety appearance. They are
-common along roadsides and on well-drained, gravelly slopes up to 5,000
-feet from west Texas to southeastern California and Chihuahua. The large
-flower heads are showy and the species is cultivated in California.
-Cases are on record of sheep and goats on overgrazed ranges being
-poisoned by eating this plant.

-
-
-Covering vast stretches of open desert with a carpet of yellow bloom
-following wet winters, goldfields is an appropriately named spring
-flower found at elevations below 4,500 feet. The low-growing plant
-produces small but attractive blossoms on mesas and plains, March to
-May, from central and southern Arizona to California, and Baja
-California. Horses graze _Baeria_ avidly, but are annoyed by a small fly
-that frequents the fragrant blossoms, giving the plant the name “fly
-flower” in some localities.

-                             94. Chaenactis
-
-
-Probably because it is one of the attractive white desert flowers,
-chaenactis is popularly called “morning bride.” A larger,
-yellow-flowered species, _Chaenactis lanosa_, found on the California
-deserts, is called “golden girls.” Both are spring flowering annuals
-and, in common with other members of the genus, sometimes called
-“pincushion plants.” “Morning bride” is often found growing about the
-bases of creosotebushes, thriving at elevations between 1,000 and 3,500
-feet in southern Nevada, western Arizona, and southeastern California.

-
-
-Rarely considered beautiful, the groundsels are common and widespread,
-and are readily recognized by the untidy appearance of the large flowers
-which are sometimes almost 2 inches in diameter. The rather delicate,
-stringy foliage is sometimes covered with cottony threads. One species
-is called “ragwort.” Douglas groundsel is a shrubby plant sometimes as
-much as 3 feet high, common in sandy washes and on dry foothill slopes.
-It occurs from southern Utah and Arizona to California and Mexico,
-between 1,000 and 6,000 feet. At lower elevations these plants bloom at
-almost any time of year.

-
-
-Everyone recognizes the thistles with their prickly leaves and stems,
-and large flowers ranging in color from white to lavender, pink and
-purple. Several species grow in the deserts, the New Mexico species
-being widespread at elevations from 1,000 to 6,000 feet in Colorado and
-Nevada south through New Mexico and Arizona to California, blossoming
-from March to September. Navajo and Hopi Indians are reported to use
-thistles medicinally. The nectar of some species is eagerly sought by
-hummingbirds.

-
-
-A very attractive plant, desert dandelion has several flower stalks from
-a few inches to a foot tall. Some of the blossoms may be nearly 2 inches
-in diameter. This annual is common in open, sandy basins, where it is a
-conspicuous contributor to the spring flower spread, blooming from March
-through May in the creosotebush belt of Arizona and southern California.
-It has been reported from as far north as Idaho and Oregon. Sometimes a
-single plant has 10 or 12 flower heads in blossom at the same time.

-
-
-There are many species of malacothryx native to the western and
-southwestern United States. Some are locally called “desert dandelion,”
-“snake’s head,” “yellow saucers,” and “cliff aster.” _Fendleri_ is one
-of the smaller species, with stems only 4 or 5 inches long, rising from
-a rosette of bluish-green leaves. Blooming from March to June, this
-delicate relative of the common dandelion covers with its pale yellow
-flowers rocky slopes and sandy plains and mesas, at elevations between
-2,000 and 5,000 feet from West Texas to western Arizona.

-
-
-Also called “tackstem” because of the numerous dark-colored, tack-shaped
-glands protruding from the stem, this white-flowered, branching annual
-blossoms from March to May at elevations of 500 to 4,000 feet. It is a
-conspicuous item of the spring flower display from west Texas to
-southern California and northern Mexico. A similar species with yellow
-flowers, _Calycoseris parryi_, common at elevations around 3,000 feet,
-blooms in March and April. It is found in southwestern Utah, Arizona,
-and southern California.

-
-
-Naturalized from Europe and generally considered a weed, sowthistle is
-found in waste grounds and along roadsides from near sea level to 8,000
-feet. It blossoms from February to August, the flowers becoming cottony
-seed heads as conspicuous as the blooms. A close relative, _Sonchus
-oleraceus_, which blossoms from March to September, produces a gum from
-the drying of the sap, reportedly a powerful cathartic. It has also been
-used as a treatment for persons suffering from the habitual use of opium
-derivatives.

-1.F.
-
-1.F.1. Project Gutenberg volunteers and employees expend considerable
-effort to identify, do copyright research on, transcribe and proofread
-works not protected by U.S. copyright law in creating the Project
-Gutenberg-tm collection. Despite these efforts, Project Gutenberg-tm
-electronic works, and the medium on which they may be stored, may
-contain "Defects," such as, but not limited to, incomplete, inaccurate
-or corrupt data, transcription errors, a copyright or other
-intellectual property infringement, a defective or damaged disk or
-other medium, a computer virus, or computer codes that damage or
-cannot be read by your equipment.
-
-1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
-of Replacement or Refund" described in paragraph 1.F.3, the Project
-Gutenberg Literary Archive Foundation, the owner of the Project
-Gutenberg-tm trademark, and any other party distributing a Project
-Gutenberg-tm electronic work under this agreement, disclaim all

-received the work on a physical medium, you must return the medium
-with your written explanation. The person or entity that provided you
-with the defective work may elect to provide a replacement copy in

-without further opportunities to fix the problem.
-
-1.F.4. Except for the limited right of replacement or refund set forth

-additions or deletions to any Project Gutenberg-tm work, and (c) any
-Defect you cause.
-
-Section 2. Information about the Mission of Project Gutenberg-tm
-
-Project Gutenberg-tm is synonymous with the free distribution of
-electronic works in formats readable by the widest variety of
-computers including obsolete, old, middle-aged and new computers. It
-exists because of the efforts of hundreds of volunteers and donations
-from people in all walks of life.
-
-Volunteers and financial support to provide volunteers with the
-assistance they need are critical to reaching Project Gutenberg-tm's
-goals and ensuring that the Project Gutenberg-tm collection will
-remain freely available for generations to come. In 2001, the Project
-Gutenberg Literary Archive Foundation was created to provide a secure
-and permanent future for Project Gutenberg-tm and future
-generations. To learn more about the Project Gutenberg Literary
-Archive Foundation and how your efforts and donations can help, see
-Sections 3 and 4 and the Foundation information page at
-www.gutenberg.org
-
-
-
-Section 3. Information about the Project Gutenberg Literary Archive Foundation
-
-The Project Gutenberg Literary Archive Foundation is a non profit
-501(c)(3) educational corporation organized under the laws of the
-state of Mississippi and granted tax exempt status by the Internal
-Revenue Service. The Foundation's EIN or federal tax identification
-number is 64-6221541. Contributions to the Project Gutenberg Literary
-Archive Foundation are tax deductible to the full extent permitted by

-
-Section 4. Information about Donations to the Project Gutenberg
-Literary Archive Foundation
-
-Project Gutenberg-tm depends upon and cannot survive without wide
-spread public support and donations to carry out its mission of
-increasing the number of public domain and licensed works that can be
-freely distributed in machine readable form accessible by the widest
-array of equipment including outdated equipment. Many small donations
-($1 to $5,000) are particularly important to maintaining tax exempt
-status with the IRS.
-
-The Foundation is committed to complying with the laws regulating
-charities and charitable donations in all 50 states of the United
-States. Compliance requirements are not uniform and it takes a
-considerable effort, much paperwork and many fees to meet and keep up
-with these requirements. We do not solicit donations in locations
-where we have not received written confirmation of compliance. To SEND
-DONATIONS or determine the status of compliance for any particular
-state visit www.gutenberg.org/donate
-
-While we cannot and do not solicit contributions from states where we
-have not met the solicitation requirements, we know of no prohibition
-against accepting unsolicited donations from donors in such states who
-approach us with offers to donate.
-
-International donations are gratefully accepted, but we cannot make
-any statements concerning tax treatment of donations received from
-outside the United States. U.S. laws alone swamp our small staff.
-
-Please check the Project Gutenberg Web pages for current donation
-methods and addresses. Donations are accepted in a number of other
-ways including checks, online payments and credit card donations. To
-donate, please visit: www.gutenberg.org/donate
-
-Section 5. General Information About Project Gutenberg-tm electronic works.
-
-Professor Michael S. Hart was the originator of the Project
-Gutenberg-tm concept of a library of electronic works that could be
-freely shared with anyone. For forty years, he produced and
-distributed Project Gutenberg-tm eBooks with only a loose network of
-volunteer support.
-
-Project Gutenberg-tm eBooks are often created from several printed
-editions, all of which are confirmed as not protected by copyright in
-the U.S. unless a copyright notice is included. Thus, we do not
-necessarily keep eBooks in compliance with any particular paper
-edition.
-
-Most people start at our Web site which has the main PG search
-facility: www.gutenberg.org
-
-This Web site includes information about Project Gutenberg-tm,
-including how to make donations to the Project Gutenberg Literary
-Archive Foundation, how to help produce our new eBooks, and how to
-subscribe to our email newsletter to hear about new eBooks.

-                    _Hints for Flower Photographers_
-
-
-If your interest in desert flowers includes a desire to obtain beautiful
-photographs of them, the following "tips" may be helpful.
-
-
-MOTION is a major hazard in still photography, and flowers, especially
-those on long, slender stems, seem to be constantly in motion stimulated
-by the ever-present desert breeze. The practical solution to this
-problem is to take your photographing jaunts, if possible, in the early
-morning when the air is most likely to be motionless. A flower picture
-blurred by motion is a complete flop!
-
-Except for motion, nothing will irritate you more often than the abrupt,
-frequent, and marked CHANGES IN LIGHTING due to small clouds passing
-over the sun. Again, early morning has an advantage in normally
-cloudless desert skies. Clouds may be expected after 10 o'clock on many
-days.
-
-
-DEPTH OF FIELD is highly important in flower photography, and you will
-be gratified with the results if you take pains to have all parts of the
-picture, except the background, in sharp focus. This desirable objective
-has become less difficult to attain with the advent of "faster" films
-which enable you to use the required small diaphragm "stop" without too
-greatly reducing the shutter speed, and still obtain adequate exposures.
-
-
-Too many flower photographers fail to get really CLOSE UP PICTURES. A
-single blossom or a small cluster of blossoms provides a much more
-attractive and significant picture than an entire plant. One blossom
-with, perhaps, a bud, one fruit, and a trace of foliage, if well
-composed, is tops among flower pictures. This objective requires camera
-equipment with the ability to focus on objects close to the lens. Also
-it complicates the goal of getting all parts of the picture into sharp
-focus.
-
-
-UNCLUTTERED BACKGROUNDS are a "must" in flower pictures. You might
-consider joining the flower photographers who carry with them plain gray
-or variously tinted background cards or light-weight boards. Such a card
-or board of contrasting color, when placed behind the blossom, will
-accomplish wonders in giving prominence to the flower. One method of
-obtaining a dark background is to ask someone (if you are a
-contortionist you can do it yourself) to stand in such a position as to
-cast a shadow on the ground or foliage behind the subject. The sky makes
-an excellent background, and you will find it useful whenever you can
-set your camera below the level of the subject.
-
-
-With the foregoing points in mind, study the pictures in this booklet
-with the aim of trying to surpass them in quality. By exercising care
-and patience, you should be able to do so.

-
-
-                              _The Desert_
-
-When Webster defined a desert as a "dry, barren region, largely treeless
-and sandy" he was not thinking of the 50,000 square mile Great American
-Desert of the southwestern United States and northern Mexico. Most of it
-is usually dry and parts may be sandy, but as a whole, it is far from
-barren and treeless. Heavily vegetated with gray-green shrubs, small but
-robust trees, pygmy forests of grotesque cactuses and stiff-leaved
-yuccas, and myriads of herbaceous plants, the desert, following rainy
-periods, covers itself with a blanket of delicate, fragrant wildflowers.
-Edmund C. Jaegar, author of several books on deserts, reports that the
-California deserts alone support more than 700 species of flowering
-plants.
-
-The late Dr. Forrest Shreve, for many years Director of the Desert
-Laboratory of the Carnegie Institution near Tucson, Arizona, defined a
-desert as "a region of deficient and uncertain rainfall." He divided the
-Great American Desert into four major sections: (1) _Chihuahuan_
-(chee-WAH-wahn), including the Mexican States of Chihuahua and Coahuila
-(coa-WHEE-lah), southwestern Texas, and south-central New Mexico; (2)
-_Sonoran_, including Baja California, southwestern Arizona, and
-northwestern Sonora; (3) _Mojave_ (moh-HAH-vee), Colorado, including
-south-eastern California and extreme southern Nevada; (4) _Great Basin_,
-including Nevada, Utah, southwestern Idaho and southeastern Oregon.
-
-Since the steppes and mesas of the Great Basin Desert have generally
-lower temperatures, higher elevations, and greater precipitation than
-the other three sections, we are not including its flowers in this work.
-
-
-                    _Why and When Do Deserts Bloom?_
-
-The Great American Desert produces, when conditions are favorable, a
-gorgeous exhibition of wildflowers. Trees, shrubs, and herbs all
-contribute to the splendor of the display. Soil composition, slope and
-exposure, suitable temperatures, and adequate moisture are essential to
-plant growth and flower production.
-
-Moisture is the uncertain factor, and years may pass without enough
-rainfall to stimulate plant growth. Rain of less than 0.15 inch is
-wasted as far as desert plants are concerned, for the moisture
-evaporates before penetrating the soil. Some annuals produce seeds
-having water-soluble germination inhibitors in their coverings, hence
-fail to sprout, even after rain, unless the moisture totals at least
-half an inch.
-
-When soil moisture from December and January rainfall is enough to
-support potential plants it dissolves the seed coats, and the desert
-floor is soon carpeted with eager green seedlings. When winter rains are
-scant, as is so often the case, the dormant seed population fails to
-germinate and the spring flower display doesn't appear. There is no sure
-way to forecast a spectacular blossom year, for a sudden cold wave or
-period of drying winds may literally nip in the bud a potential season
-of brilliant bloom. A great flower year may occur only once in a decade.
-
-Perennials are more dependable than annuals, since some of them,
-particularly cactuses and other succulents, have water storage tissues
-in their stems or roots. These perennials may be counted on to blossom
-each year, but with much less abandon than after winters of above normal
-precipitation. Many perennials have surprisingly extensive root systems.
-Fascinating are the ways by which plants manage to thrive under severe
-conditions of desert heat and drought. As we have seen, most annuals lie
-dormant as seeds until suitable moisture and temperature occur. Then
-they grow very rapidly, to bloom and mature seeds while the soil still
-has moisture. Winter rains produce spring-blooming ephemerals, and
-summer showers produce summer "quickies."
-
-Another group of plants, including the ocotillo (oh-koh-TEE-yoh), slows
-down life processes to become dormant during dry periods, even to
-dropping all leaves. When rains come they put on new leaves, several
-times a year if necessary.
-
-Cactuses and other succulents gorge themselves with water when the soil
-is wet, releasing moisture very sparingly from storage tissues during
-the "long dry." Some have discarded or reduced foliage, or have covered
-leaf surfaces with varnish or wax, to decrease to a minimum the loss of
-vital moisture through transpiration.
-
-
-                    _Identifying Desert Wildflowers_
-
-Unless you are a botanist, identification of flowers by measuring and
-counting their various parts, as described in technical keys, is
-generally too complicated to be practical. Several years ago,
-recognizing this problem, I authored a book, _Flowers of the Southwest
-Deserts_, illustrated by Jeanne R. Janish and published by the
-Southwestern Monuments Association, designed to aid the wildflower
-fancier in plant identification by color-grouping the flowers. With Mrs.
-Janish's superb illustrations pointing out each plant's most obvious
-characteristics, it has proved an excellent field guide. However, the
-demand for natural color flower portraits could not go unheeded, and
-this book is the result. The two books complement each other, although
-each fills a need in its own right. Used together, they make you more
-positive of some identifications.
-
-Probably the best way to become acquainted with a flower is to be
-introduced to it by someone. But there is one catch to this method--one
-plant may be known by many aliases.
-
-When the Spaniards came into the Southwest over 400 years ago they found
-Indians had names for some flowers in their own languages. The Spaniards
-added their names, and later the Americans added English names. Some of
-these names were of similar-appearing but quite different flowers they
-had known "back East." Later, scientists studied the desert plants, and
-gave them all Latin names.
-
-To assist in standardizing names of desert flowers, this booklet gives
-preference in its headings to scientific and common names found in
-_Arizona Flora_, by Kearney and Peebles, Second Edition, 1960. Common
-names found in _Texas Plants, A Checklist and Ecological Summary_, 1962,
-by F. W. Gould, also have been used. In addition, placed within the
-text, are some of the more widely used common names that we have
-encountered. Tree names, both common and scientific, follow the
-_Checklist of Native and Naturalized Trees of the United States_, by
-Elbert L. Little, Jr., 1953.
-
-There are many desert flowers, some quite common, for which there was
-not space in this booklet. If you wish to broaden your acquaintance to
-include more, we recommend, for added reading publications listed in the
-back.
-
-The author wishes to express here sincere thanks to Mrs. Pauline M.
-Patraw, Santa Fe botanist, for assistance in identifying many of the
-flowers pictured here. For assistance in checking identifications, the
-author is indebted to Miss Barbara Lund, Park Naturalist, National Park
-Service; to Dr. Charles T. Mason, Jr., Curator of the Herbarium,
-University of Arizona Tucson; and to Dr. W. B. McDougall, Curator of
-Botany, Museum of Northern Arizona, Flagstaff.

-
-  When Paloverde trims her golden gown,
-  And Deerhorn dons her filaments of white;
-  When tall Saguaro fits his fragrant crown
-  In preparation for the party night;
-  When bats across the ruby sunset dance,
-  When Ocotillo lights his candle's flame,
-  When verdure carpets Desert's wide expanse,
-  Then Spring is in the Southwest once again.
-
-  The linnets in their scarlet vests and caps
-  Are first to answer Spring's insistent call,
-  While white-crowned sparrows scan their travel maps,
-  Discussing details of the coming ball.
-  Then thrashers practice every morn and eve
-  The songs they'll sing upon that night of nights,
-  While phainopeplas, in their haste to leave,
-  Dash back and forth in short, impatient flights.
-
-  The desert halls glow bright as time draws near.
-  Each cactus wears her frilled and perfumed dress.
-  Ground squirrels, for this joyous time of year,
-  Sport their best furs. The rabbits do no less.
-  From far and near the desert folk have come

-
-                          1. Longleaf ephedra
-
-
-Commonly called "Mormon tea," there are many species of ephedra
-(ef-FED-rah) growing throughout the Southwest. This yellow-green,
-stringy-stemmed shrub with tiny, scale-like leaves, is usually 3 to 4
-feet tall, but sometimes reaches a height of 12 feet. Its small,
-fragrant, springtime flowers grow in dense clusters that attract
-insects. Some species provide winter forage for cattle and are said to
-be browsed by bighorn sheep. Pioneers brewed a palatable drink from the
-dried stems. Certain Indian tribes considered the brew a tonic,
-beneficial for treatment of syphilis and other diseases. The drug,
-ephedrine, comes from a Chinese member of this genus.

-
-                             2. Common reed
-
-
-Somewhat resembling bamboo, carrizo grows in dense thickets in marshes,
-along river banks, and in other wet locations. Largest of the grasses,
-it sometimes attains a height of 12 feet. The large, tassel-like flower
-heads appear from July to October and create a spectacular mass display.
-The horizontal rootstalks interlock, crowding out other plants. A single
-rootstalk may extend 30 feet. The straight, hollow stems served Indians
-as arrowshafts, pipestems, and loom rods. Along the Mexican border the
-leaves are woven into mats and the long, sturdy stems are used as
-screens and in roofing native houses.

-
-
-                         3. Prairie spiderwort
-
-
-Because of its slender, drooping leaves, this delicate blue-to-violet,
-three-petaled flower might easily be mistaken for a lily. Plants grow
-from 8 to 18 inches high. A perennial, the spiderwort's thick, succulent
-roots enable it to produce blossoms from April to September. Not
-abundant, it is usually found in moist locations in desert mountain
-ranges at elevations above 2,500 feet. Flowers form in clusters at the
-tip of a plant's stem, and are pollenized by bumblebees that eat the
-pollen.

-
-                             4. Desertlily
-
-
-Limited in its range to the desertlands of southern California and
-southwestern Arizona, the desertlily or ajo (AH-hoe) resembles a small
-easter lily. During dry seasons the plants do not bloom, but following
-wet winters each deeply-buried bulb sends up a vigorous shoot which may
-be from 6 inches to 2 feet tall, with a bud cluster at its tip. The
-delicately fragrant flowers may appear in late February, with some tardy
-bloomers still in evidence in early May. Bulbs were dug and eaten by
-Indians and, because of their flavor, were called ajo (garlic) by the
-Spanish pioneers. The town of Ajo and a nearby valley and mountain range
-in southwestern Arizona were named for this plant.

-
-
-                              5. Mariposa
-
-
-Similar in appearance to the segolily, State flower of Utah, weakstem
-mariposa, sometimes called "straggling butterfly lily," varies in color
-from white to pale purple. The slender stem is not erect, like other
-mariposas, of which there are many species, but wanders over the ground
-or makes its twisting way among the branches of low shrubs. It grows at
-elevations up to 4,000 feet on slopes and benches of mountains of the
-Mojave-Colorado Desert, in the Death Valley area, and in the desert
-mountains of southern Arizona, blossoming during April and May. Indians
-and pioneers ate the bulbs.

-
-
-                           6. Golden mariposa
-
-
-Considered by some botanists as a distinct species, this mariposa or
-"butterfly tulip" is found in the higher mountains of the eastern
-Mojave-Colorado Desert and also in the vicinity of the Painted Desert of
-northern Arizona. Common in Petrified Forest National Park from May to
-July, the bright yellow flowers make an eye-catching display among the
-colorful pieces of petrified wood covering the ground. The bulbs can
-withstand severe cold, but suffer during winters when there is frequent
-freezing and thawing.

-
-
-
-
-                           7. Desert mariposa
-
-
-Brightest of the mariposas, the short-stemmed, flame-like flowers
-usually appear singly, but may occur in patches, producing in April a
-spectacular display visible from a long distance. Plants growing under
-bushes elongate their stems to elevate their blossoms into the sunlight.
-Occasional in the Mojave-Colorado Desert, this species is abundant in
-the foothills of some of southern Arizona's mountain ranges, exceeding
-even the goldpoppy in the neon-like brilliance of display. _Mariposa_ is
-Spanish for butterfly, and the genus name _calochortus_ is Greek for
-beautiful grass.

-
-                           8. Soaptree yucca
-
-
-Common throughout the Southwest, the many species of yuccas (YUH-kuhs)
-are of two major groups, the narrow-leaf and the wide-leaf. Called
-"soaptree" because of its height (maximum 30 feet) and the fact that its
-roots contain saponin, soaptree yucca or _palmilla_
-(pahm-EE-yah--"little palm") belongs in the narrow-leaf group. From
-southwestern Arizona across southern New Mexico, and from west Texas
-southward into the Mexican states of Chihuahua and Sonora, this
-spectacular plant blossoms in May and June on desert grasslands from
-2,000 to 6,000 foot elevations. Cattle eat the young flower stalks, and
-Indians used the leaf fibers for making fabrics, basketry, and other
-items. The yucca is the State flower of New Mexico.

-
-
-
-
-                             9. Joshua-tree
-
-
-Another of the narrow-leaf yuccas and largest of the genus, the
-joshua-tree is restricted in its range to the Mojave-Colorado Desert, of
-which it is the principal indicator. Blossoms, which do not open as wide
-as those of other species, grow in tight clusters at the tips of the
-branches, appearing in March and April. Joshuas do not blossom every
-year, the interval between flowerings depending upon rainfall and
-temperature. A small night lizard is dependent upon the joshua-tree, at
-least 25 {species of birds find nesting sites in it, and numerous
-insects, spiders, and scorpions live in its dried leaves and fallen
-branches.}

-
-
-
-                            10. Torrey yucca
-
-
-Unlike the narrow-leaf soaptrees which produce dry, capsular fruits, the
-wide-leaf yuccas bear fleshy fruits which Indians cooked and ate.
-Indians also used the leaf fibers in weaving fabrics. Roots contain
-saponin and the Indians still cut them up and use the pieces for soap,
-especially as a shampoo. The stiff, fleshy leaves with needle-sharp tips
-give the plant the name "Spanish bayonet." Torrey yucca blooms in April
-in southeastern New Mexico and west Texas, with similar plants, _Yucca
-schottii_ in southern Arizona, and _Yucca schidigera_ in the
-Mojave-Colorado Desert.

-
-
-                            11. Giant yucca
-
-
-Massive and thick-stemmed, the locally-named "giant dagger" is
-supposedly limited in its native range in the United States to Brewster
-County, Texas. A colony (_Yucca faxoniana_) resembling this species has
-been reported recently in McKittrick Canyon in the Guadalupe Mountains.
-An extensive forest of these spectacular plants has given the name
-Dagger Flat to a broad valley in the Sierra del Carmen of Big Bend
-National Park. Usually blossoming in April, the massive, white flower
-clusters gracing the crowns of thousands of these majestic yuccas create
-a never-to-be-forgotten spectacle. A small night-flying moth is the
-yuccas' pollenizing agent and, in return for this essential service,
-lays her eggs in the plants' ovaries where the young feed on the
-developing seeds.

-
-
-
-
-                             12. Sacahuista
-
-
-Sometimes confused with the yuccas, the several species of "beargrass"
-or "basketgrass" have pliant, grasslike leaves, small flowers, and
-papery fruits. The plumelike blossom panicles open in May and June. The
-plants favor rocky hillsides, and rarely occur on valley floors. Indians
-roasted the tender bud stalks for food, and cattle browse the leaves
-when other vegetation is lacking. Mexicans, in weaving basketry, use the
-entire leaves, which are especially desirable for fashioning basket
-handles.

-
-[Illustration: SACAHUISTA]
-
-
-
-
-                               13. Sotol
-
-
-Also likely to be confused with the yuccas, sotol has a basal cluster of
-pliant, ribbonlike leaves edged with hooked thorns, and a tall flower
-stalk bearing at its upper end a dense panicle of small, creamy
-(sometimes brown) flowers. Blossoming in May and June, the maturing
-flower clusters remain attractive throughout the summer. Mexicans split
-the succulent basal crowns and allow the sap to ferment, producing the
-fiery alcoholic beverage, sotol (SOH-tole). Desert-dwelling bighorn
-sheep are said to browse the tough leaves. The stiff leaf bases, when
-pulled from the cluster, form the "desert spoons" sold in some curio
-stores.

-
-
-                               14. Agave
-
-
-Many species of agaves (ah-GAH-vees) or "century plants" attract
-attention on desert hillsides when they send up their tall blossom
-stalks in June and July. The thick, fleshy, sharp-tipped leaves form a
-basal rosette. Some of the larger species may require 10 to 20 years to
-store enough plant food to produce the sturdy, fast-growing flower
-stalk. After blossoming, the exhausted plant dies. _Agave scabra_, one
-of the spectacular forms, is limited in its range to the Chisos
-Mountains of Big Bend National Park, Texas.

-
-                            15. Parry agave
-
-
-Another of the large "century plants," Parry agave blooms from June to
-August, producing spectacular displays on hillsides in northern Mexico,
-southern New Mexico, and southern Arizona. Some of the larger agaves are
-called mescal (mess-KAHL) because of a potent alcoholic beverage of that
-name distilled from the fermented sap derived from the bud stalks.
-Tequila (tee-KEEL-ah), the famous native drink of Mexico, also is
-distilled from fermented agave juices, and the beerlike pulque
-(pool-KAY) has a similar derivation. Indians roasted the bud stalks in
-stone-lined pits covered with hot rocks. Some of these pits may still be
-seen.

-                            16. Lechuguilla
-
-
-One of the common plants of the Chihauhuan Desert and considered the
-principal indicator of that region, lechuguilla (lay-chu-GHE-ah) covers
-the ground so densely in some places that it is impossible to walk
-through it. The stiff, erect, needle-tipped, banana-shaped leaves are a
-hazard to man and beast. The flowering stalk, which blossoms in May and
-June, is unbranched and flexible, bending gracefully in the desert
-breeze. Deer and cattle nip off the tender buds. Mexicans weave the
-tough leaf fibers into coarse fabrics; and the roots, called _amole_,
-produce suds when rubbed in water.

-                              17. Canaigre
-
-
-This coarse, herbacious perennial is one of the early spring flowers of
-the desert, sometimes blooming along road shoulders and in sandy washes
-in late February and March. Commonly called wild rhubarb, its sap and
-roots are high in tannin content, and its delicately pink fruits are
-more attractive than the blossoms. Indians and Mexicans use the leaves
-for greens. Papago Indians of Arizona roast the leaves and use the roots
-for treating colds and sore throat. This plant is a close relative of
-European dock, several species of which have become naturalized in North
-America.

-                       18. Trailing-four-o'clock
-
-
-Blossoming from April to October, trailing allionia, known in some
-places as "trailing four o'clock" or "windmills," is a spreading annual
-with small but colorful blossoms on long, trailing stems. The prostrate
-branches are sticky, so are often covered with grains of sand and flecks
-of mica. What appears to be one blossom is actually three flowers,
-giving it the name "pink three-flower." It is found on dry, sandy
-benches throughout desert regions of the Southwest. Fruits are winged.

-
-                            19. Sand-verbena
-
-
-One of the early spring flowers, sand-verbena creates spectacular mass
-displays, sometimes alone, usually intermingling with other colorful
-early bloomers such as bladderpod and sundrops, which grow on road
-shoulders and sandy flats. The flowers are delicately fragrant,
-especially at night. Semi-prostrate in habit, sand-verbena leaves are
-covered with a dense growth of short, soft hairs which retard the loss
-of moisture so essential to desert plants. This annual is common from
-southern California and southern Arizona into Sonora.

-
-
-Closely related to the orange California-poppy, official flower of the
-Golden State, the desert species is a bright yellow annual. Following
-warm, wet winters clusters of these glorious blooms dot the hillsides in
-late February or early March. By April they may cover the slopes with a
-blanket of gold interwoven with the blue threads of lupines and purple
-patches of escobita owlclover. When other early spring vegetation is
-scarce, cattle graze the plants. Flowers open only during sunny hours,
-remaining tightly closed at night and on cloudy days.

-                            21. Pricklepoppy
-
-
-Not restricted to a desert habitat, this spiny-leafed perennial is
-widespread on dry soils from Nebraska to Wyoming and from Texas to
-southern California and Mexico. Abundant throughout the summer, the
-flowers may be found, in warm climates, during every month of the year.
-Copious spines and the acrid yellow sap make the plants distasteful to
-cattle, so a heavy growth of pricklepoppy may be an indicator of an
-overgrazed range. Also called "thistlepoppy," a single plant may be
-graced by a dozen or more fragile flowers, each ready to be replaced by
-one or more prickly buds. The seeds are said to contain a powerful
-narcotic.

-
-
-Also known as "yellow cups," this plant is limited in its range to the
-Mohave-Colorado Desert. Having smaller blossoms than the goldpoppy with
-which it might be confused, this showy annual blooms March to May in dry
-washes and on stony hills below 4,500 feet. The foot-high plants
-sometimes form massed displays accented by splashes of bright red where
-clumps of beavertail pricklypear mark small, rocky islands, or where
-patches of ocotillos wave their scarlet-tipped wands in the spring
-breeze.

-Found at elevations above 1,000 feet, spectaclepod is one of the
-long-flowering species blooming from February to October. The large
-flower heads are pleasantly fragrant, and the peculiar, flat, double
-fruits resemble tiny spectacles protruding at right angles to the stem.
-This species is found in the Petrified Forest area of northern Arizona,
-and Hopi Indians are reported to use the plant in treating wounds.
-Another species, California spectaclepod, is often abundant, covering
-sandy flats of the lower deserts. This species blooms from February
-through April and sometimes again in the fall.

-
-
-Another early bloomer, February to May, bladderpod is one of the first
-spring flowers to spread its yellow carpet across the desert flats. The
-small, low-growing plants lift numerous clusters of four-petaled
-flowers, forming an understory of color among the taller herbs. In some
-localities, bladderpods are called "beadpods" because of the spherical
-fruits. The plants afford good forage for cattle. A close relative, with
-white to purple flowers, is found from Texas to Arizona and Mexico,
-starting to blossom in January during warm winters.

-
-
-A showy plant with a large terminal cluster of four-petaled flowers, it
-is frequently called "desert wallflower." When growing under shrubs it
-often extends its stems 2 feet or more to reach up into the sunshine.
-Usually blossoming in March, some plants may be found blooming at almost
-any time during the summer to as late as September.

-
-
-With mimosa-like leaves and long-stamened flowers growing in clusters,
-false-mesquite, "calliandra," or "fairy duster" is a small, straggling
-bush, quite Japanesy in appearance, from a few inches to 3 feet high. It
-blossoms from February to May, and is quite common below 5,000 feet from
-west Texas to southern California and northern Mexico. In California it
-is especially abundant along the east side of the Chocolate Mountains.
-During periods of drought the leaves enter a state of continued wilt,
-but revive promptly when rain comes.

-
-
-Also known by such descriptive names as "tear-blanket" and
-"wait-a-minute," catclaw acacia is one of the notoriously thorny shrubs
-or small slender trees of the rocky hillsides and borders of desert
-washes. Flowers are fragrant and, during the blooming period in May,
-attract many insects, including honey bees, which gather and store
-nectar that makes high quality honey. The stringbean-like fruits turn
-red in late summer and, if abundant, make a spectacular show. These
-fruits were ground into meal and used for food by Arizona and Mexican
-Indians. Thickets of catclaw acacia provide havens of refuge for birds
-and rabbits pursued by hawks or other predators.

-
-
-Armed with long, slender, straight white spines, giving it the name
-"white-thorn," this pretty flowering shrub is abundant over large areas
-of dry slopes and mesas from Texas to Arizona and Mexico at 2,300 to
-5,000 feet. It is often used as a decorative in landscape plantings
-around buildings. Blossoms are fragrant and sometimes continue from May
-to August; the shrub occasionally blooming again in November. Cattle and
-horses eat the bean-like fruits.

-
-
-Mesquite (mess-KEET) is a many-branched tree 15 to 23 feet tall, which
-flowers from late April to June. It is common bordering desert washes,
-often forming dense thickets. The flowers furnish honey bees and other
-insects with nectar, and the long, sweet pods ripen in autumn, providing
-food for livestock. The fruits have long been a staple in the diet of
-desert Indians, who used the trunks, roots, and branches of the trees
-for firewood and the dried gum-like sap to mend pottery and as a black
-dye. The inner bark provided the Indians with materials for basketry and
-coarse fabrics. Roots of mesquite trees have been reported to penetrate
-to a depth of 50 to 60 feet to tap sources of ground water.

-                               30. Senna
-
-
-Blossoming from April to October, this species is common at elevations
-between 1,000 and 3,000 feet Nevada to New Mexico, Arizona, California,
-and northwestern Mexico. There are fifteen or more other species, many
-of which are found in a desert habitat and range in size from
-low-growing herbs to small shrubs 3-5 feet high. Senna is sometimes
-called "rattlebox" because the nearly ripe seeds rattle in their woody
-pods when the plant is stirred, startling the hiker who immediately
-thinks "rattlesnake!" A closely related species, _leptocarpa_, is noted
-for its foul-smelling foliage.

-
-
-Perhaps the most dependable of spring bloomers, blue palo-verde trees
-cover themselves with masses of yellow blossoms in April and May.
-Usually found alongside desert washes, they mark these ephemeral stream
-courses as paths of gold threading the open desert. During much of the
-year the trees are relatively leafless, the green bark of trunk and
-branches taking over the function of leaves. The word _palo-verde_
-(PAH-low-VEHR-dee) means "green stick" in Spanish, referring to the
-color of the bark.

-
-
-Not a southwestern desert native, this striking shrub, 3 to 10 feet
-high, was introduced from South America and has escaped from cultivation
-to establish itself in parts of the desert where conditions are
-suitable. The blossoms are showy but ill-smelling, and are popular as
-ornamentals about homes, especially in Mexico. The shrub's principal
-advantage in landscape plantings is its long blossoming period, which
-sometimes lasts from April to September.

-
-
-This is but one of many species of lupine, both annual and perennial,
-common throughout the West at nearly all elevations. Perhaps the most
-publicized is the "Texas" lupine, or "bluebonnet," hailed by Texans as
-their State flower. Desert species are early bloomers, sometimes
-appearing in protected sandy soils and on highway shoulders in January.
-In favorable seasons masses of these handsome blue to violet blossoms
-color desert hillsides with acres of fragrant bloom. Sometimes growing
-in pure stands, often mixed with a variety of other spring flowers,
-lupines may usually be found blossoming as late as June.

-
-
-Considered one of the more handsome of the desert perennials, the
-"adonis" lupine, as it is known in southern California, is found near
-sandy washes in the high desert. It is especially abundant in Joshua
-Tree National Monument. The name _adonis_ refers to its great beauty.
-The name _lupinus_ is derived from the Latin _lupus_ meaning wolf,
-because these plants were at one time thought to be soil predators.
-Actually, as with other members of the pea family, lupines are able to
-take atmospheric nitrogen and leave it in the ground, thereby increasing
-rather than depleting soil fertility.

-
-
-Better known as "smoketree," this silvery-gray, seemingly leafless shrub
-grows in and along sandy washes below 1,500 feet, throughout the
-Mojave-Colorado Desert. At a distance it resembles a plume of smoke
-rising from a campfire. Its small but violet to indigo flowers cover it
-with a gorgeous blue blanket in May, making it one of the really
-handsome desert shrubs. It requires ample supplies of water, hence is
-restricted to washes that carry runoff from both winter rains and summer
-downpours. The seeds sprout readily, and the seedlings with their
-well-formed leaves look very unlike their parents. Few seedlings survive
-the hazards of drought or being smothered by sand carried down the
-washes by flash floods following cloudbursts.

-
-
-Noted for its royal purple flowers, this low shrub, less than 3 feet
-high with peculiar zig-zag branches, blossoms from April to June. In
-common with other daleas (day-LEE-ahs) it is usually called "indigobush"
-or "peabush." It is normally found below 3,000 feet in desert mountain
-ranges from southern Utah through Arizona and southeastern California.
-There are many species of dalea in the desert, all characterized by deep
-blue to indigo and rose-violet flowers, which attract attention by their
-beauty. Indians used the extract from twigs for dyeing basketry.

-
-
-Thriving only in a frost-free climate, this is among the largest and
-most beautiful of desert evergreen trees. It is usually found along
-sandy washes, mingling with mesquites and paloverdes. It is particularly
-susceptible to mistletoe infestation, which has killed or weakened many
-fine trees. Blossoming in May and June, the trees are sometimes laden
-with lavender, wisteria-like flowers. The wood is extremely hard and
-heavy, hence the tree is locally known as "ironwood," or
-_palo-de-hierro_, in Mexico. Indians ate the seeds and used the wood for
-tool handles and arrow-points. Its long-burning qualities made it
-especially desirable for fuel. As a result, many of the trees have been
-cut, making it one of the species threatened with extinction.

-
-
-Many species of "locoweed" ranging in color from deep purple to creamy
-white are found throughout the desert at nearly all elevations. They
-sometimes create extensive mass displays but are more commonly found
-mixed with other flowers. Species with bladder-like pods are called
-"rattleweed." Loco in Spanish means "crazy" and refers to the fact that
-a number of species of _astragalus_ contain selenium, which causes a
-serious disease among livestock, especially horses, that eat it and as a
-result "act crazy."

-
-
-Also called "alfileria," this species and its close relative, Texas
-filaree (_Erodium texanum_) are both early blossoming annuals, often
-widespread on plains and mesas, February to May. The flowers, although
-abundant, are small and so hidden in low-growing foliage that they
-rarely create a mass display. Texas filaree is native to North America,
-but alfileria is thought to have come from Europe with the Spaniards,
-and is now naturalized throughout the Southwest. Corkscrew-like
-appendages of the fruits are tightly twisted when dry, but untwist when
-moist, literally screwing the sharp-pointed fruits into the soil. Both
-species are excellent spring forage for livestock.

-
-
-Often erroneously called "greasewood," creosotebush is generally
-recognized as the most adaptable of all desert plants, and a definite
-indicator of the Lower Sonoran Life Zone. The shrubs cover thousands of
-square miles, often in pure stands, and flower throughout much of the
-year, but most profusely in April and May. Fuzzy white, globular fruits
-are almost as spectacular as the flowers. The plant can endure long
-periods of drought. Following rains its foliage gives off a musty,
-resinous odor, suggestive of creosote, stimulating the Mexican name
-_hediondilla_ (little stinker). In Mexico the plant is considered to
-have medicinal values and many uses. The Pima Indians boiled the leaves,
-using the decoction as an emetic and to poultice sores. They used the
-lac, found as an incrustation on the branches, to cement arrow-points
-and to mend pottery.

-
-
-Often abundant on road shoulders and in low spots where rainwater from
-hot-weather showers provides adequate moisture, "caltrop" or
-"summerpoppy," with large blossoms and attractive compound leaves,
-decorates the desert when other flowers are noticeable by their absence.
-The long, weak stems, usually prostrate, give the plants a vine-like
-appearance, but when growing under shrubs they extend upward so that the
-shrub is mistakenly thought to be blooming. Superficially resembling the
-springtime goldpoppy, Arizona-poppy has five rather than four petals,
-and may be found in bloom as late as October.

-
-
-Ranging in size from delicate 6-inch annuals to coarse, woody perennials
-4 feet high, the globemallows vary in color from creamy white to pink,
-rose, peach, and lavender. Desert-mallows flaunt their graceful,
-blossom-covered stems along roadsides or on the banks of sandy washes.
-Because some people are allergic to them, globemallows are called
-"sore-eye poppies" in parts of southern Arizona, and in Lower California
-are known as _plantas muy malas_ (very bad plants).

-
-
-Sometimes confused with tamarack because of the similarity of names,
-five-stamen tamarisk, locally called "salt-cedar," is one of several
-small tree species from southeastern Europe and western Asia which have
-become naturalized in North America. "Salt-cedar" often forms dense
-thickets on alkaline soils along stream and reservoir banks at
-elevations below 5,000 feet. Flowers, which vary in hue from deep pink
-to white, cover the trees with graceful plumes of color from March to
-August. Although valuable in retarding soil erosion, tamarisk requires
-large quantities of water, an especially undesirable characteristic in
-the arid Southwest.

-
-
-Many species of _mentzelia_, all herbs, occur in the West. Barbed hairs
-cover leaves and stems, causing the plant to cling to what it touches,
-hence a common name "stick-leaf." Flowers grow at ends of branches, and
-some species open fully only in sunlight. A close relative, _Mentzelia
-involucrata_, "sand blazing-star," is an annual, 4 to 16 inches high,
-blooming February through April, found in sandy washes below 3,000 feet
-in southwestern Arizona, southeastern California, and northern Sonora.
-_Pumila_ grows in dry stream beds and on roadsides from 100 to 8,000
-feet elevation, flowering February to October. It ranges from Wyoming
-and Utah to southeastern California and Northern Mexico.

-
-
-Also called "stingbush," this low, rounded bush is usually found growing
-from crevices in cliffs. When covered with large blossoms from April to
-September the plant has a striking appearance. The pale green leaves are
-covered with stinging hairs, strong enough to impale such small
-creatures as bats emerging from cave entrances where they grow.
-Rock-nettle is common in desert ranges of southeastern California,
-especially in the Death Valley area, to western Arizona and southern
-Nevada.

-
-
-Easily overlooked, when not in blossom, as a group of slender, fluted,
-gray-green stems hidden beneath a shrub, this cactus is truly a glorious
-thing when in flower. Beauty and fragrance of its blossoms have earned
-it the name, in Mexico, of _reina-de-la-noche_, meaning
-"queen-of-the-night."
-
-Buds unfold soon after sunset in late June or early July, perfuming the
-desert air and attracting night-flying insects. They wilt soon after
-sunrise the following morning. The large, tuberous root, which serves as
-a water-storage organ, usually weighs from 5 to 15 pounds, but specimens
-have been found weighing more than 80 pounds. Indians at one time dug
-the tubers for food. The bulbous fruits become red when mature, and are
-almost as spectacular as the flowers. This species is found from west
-Texas to western Arizona and northern Mexico.

-
-
-Largest of the cactuses in the United States, the saguaro (suh-WAR-oh)
-is limited in its principal range to southern Arizona and northern
-Mexico. Although rarely exceeding 30 feet in height, specimens 50 feet
-tall and weighing up to 10 tons, are on record. Blossoms form as huge
-bud clusters at the branch tips, opening a few at a time each night,
-usually in May, and remain open until mid-afternoon of the following
-day. Fruits of the saguaro are eaten by birds and other animals, and at
-one time were important in the diet of desert Indians. The state flower
-of Arizona and the subject of a US. postage stamp issued in February
-1962 to commemorate the 50th anniversary of Arizona's statehood, the
-saguaro is also commemorated and protected in the National Monument of
-that name near Tucson.

-
-
-Limited in its range to northwestern Mexico and the vicinity of Organ
-Pipe Cactus National Monument in southwestern Arizona, this columnar
-cactus grows in clumps of spine-covered stems, some of which may be 10
-to 15 feet in height, rarely branching, and with no central trunk.
-Blossoms open at or near the stem ends during May nights, and close the
-following day. The spine-covered fruits, about the size and shape of a
-hen's egg, have long been harvested by the Papago Indians, who boil the
-sweet juice to the consistency of syrup and store the pulp and seeds for
-winter food. The fruits are locally called _pitahaya dulce_, or sweet
-cactus fruit.

-
-
-Not only are there many species of _Echinocereus_, popularly called the
-"hedgehog cactuses," but there are also several varieties of
-_Echinocereus triglochidiatus_. One variety sometimes develops into
-cushion-like mounds composed of several hundred oblong stems huddled
-together with a seemingly precarious foothold in crevices among the
-rocks or on rocky slopes of the Mojave desert. Another grows in loose
-clusters of cylindrical stems in the higher desert grasslands up to the
-oak belt in the mountains of southern New Mexico, Arizona, and northern
-Mexico. When blossoming in May and June these clustering "hedgehogs"
-create a spectacular display.

-
-
-One of the more common species of "hedgehog," sometimes called
-"Engelmann echinocereus," the strawberry echinocereus grows as 2 to 12
-or more robust, cylindrical stems up to a foot in height, among the
-creosote bushes and bur-sages of the Sonoran and Mojave-Colorado
-Deserts, flowering from February to May. Flowers close at night and
-reopen the following morning. Blossoms vary considerably in color from
-purple to lavender. Spines, too, are variable, from gray and yellow to
-dark brown. In southeastern California, where it is common, this species
-is called "calico cactus" because of its many-colored spines. Fruits of
-some varieties (of which there are many) are edible, forming an
-important item in the diet of birds and rodents.

-
-
-Far from common but among the more beautiful of the "hedgehogs" is the
-rainbow echinocereus, also called "rainbow cactus," so named because of
-the horizontal bands of alternating red and white spines encircling the
-single, sturdy stem. It grows in rocky situations in the mountains of
-southern Arizona and northern Mexico, blossoming from June to August.
-The large flowers, of which there may be from one to four crowding
-around the crown of the plant, are often larger than the plant itself.
-Spines are small and lie densely flat over the somewhat fluted stem,
-which is from 3 to 14 inches high.

-
-Sometimes called "Texas golden rainbow," the yellow pitaya of the
-Chihuahuan Desert is similar in appearance, except for the color of its
-blossoms, to the rainbow echinocereus. Quite common in portions of Big
-Bend National Park, the Stubby, upright stems usually grow singly but
-sometimes occur in small clusters. The term _pitaya_ or _pitahaya_ is
-commonly applied along the Mexican border to cactuses bearing edible
-fruits. In Texas the term refers to the low-growing floral hedgehogs; in
-Arizona to the columnar cactuses. Pricklypear cactuses having soft,
-juicy, edible fruit are known as _tunas_.

-
-
-Massive, cylindrical, and covered with clusters of stout spines, the
-central one hook-shaped, these desert giants are often mistaken for
-young saguaros. There are several species, all locally called
-_bisnagas_, with some quite small and others attaining a height of 5 or
-6 feet. The majority produce clusters of orange to red flowers on their
-crowns in late summer, but the yellow-flowered California barrel cactus
-blossoms in the spring. Their tendency to lean toward the light causes
-many of these heavy-bodied plants to tip in a southwesterly direction,
-giving them the name "compass cactus." This group is naively believed by
-some people to contain water. Actually the slimy, alkaline sap obtained
-by mashing the pulpy flesh might conceivably save someone lost in the
-desert from dying of thirst. The pale yellow fruits are not spiney, and
-are eaten by birds, rodents, deer, and other desert animals.

-
-
-There are a number of species of the low-growing, usually dome-shaped
-mammillarias, the solitary kinds often so small as to be overlooked
-except when blooming, in late spring or early summer. Some are known as
-"fishhook cactuses" because of their long, slender, hooked spines,
-others as "pin-cushion cactuses" because of the shape of the plants. The
-large, colorful blossoms which encircle the stems mature usually to red,
-in some species green, nipple-shaped fruits. Members of this genus are
-widespread in grasslands or rocky mesas and slopes throughout the
-Southwest.

-
-
-Limited in its principal range to the Mojave-Colorado Desert, the
-beavertail is a low-growing species with flat joint-pads and
-bluish-green stems without spines. In their place are clusters of
-brownish spicules set in slight depressions in the wrinkled pads. The
-plants blossom in March and April, adding materially to the color of the
-spring flower display. The plants thrive in sandy desert soils, at
-elevations from 200 to 3,000 feet above sea level, and are found as far
-east in Arizona as Wickenburg. Cahuilla Indians cook the fruits with

-
-
-Most widely distributed of the pricklypears, Engelmann plants are large
-and spreading, sometimes forming spiney bushes 3 to 5 feet high and up
-to 15 feet in diameter. The branching stems may have from 5 to 12
-pad-joints. Flowering in April and May, the petals at first are yellow
-but turn to pink or rose with age. The plants prefer washes and benches
-in the desert grasslands, often growing with paloverdes, saguaros,
-mesquites, and lechuguilla agaves. Excessive abundance often indicates
-an overgrazed range. Fruits, called _tunas_, are purple to mahogany when
-mature, and are eaten by many birds and rodents, as well as by desert
-Indians.

-
-
-Also known as "silver cholla" (CHOY-AH) and "teddybear cactus," this
-stocky bush cactus, with a short sturdy trunk and compact, densely
-spined crown, is common on hot rocky, south-facing hillsides. Joints are
-extremely brittle and the barbed spines catch so easily in the hair of
-animals or clothing of persons that the joints appear to jump from the
-plant. Joints broken off by the wind fall to the ground and take root in
-the sandy soil, gradually developing forests of this striking cactus,
-easily recognized by the silvery sheen of the spines. The attractive
-flowers which appear from March to May blend inconspicuously with the
-spiney joints.

-
-
-Common along banks of washes and on desert flats, this cholla, also
-called "tesajo," or "Christmas cholla," is so slender-stemmed and
-sprawling in growth habit that it is easily overlooked in a tangle of
-vegetation. Its flowers, appearing in May and June, are small and
-inconspicuous, but the orange to scarlet fruits about the size and shape
-of olives, are striking eye-catchers in the fall and winter months. In
-the open the shrubby plants are rarely more than 2 feet high, but in
-thickets of northern Mexico some have become almost vinelike, growing up
-through mesquite or paloverde trees to a height of 12 feet or more. The
-species grows at elevations of 200 to 5,000 feet from Texas to western
-Arizona and northern Mexico.

-
-
-This low-growing cholla of the higher desert above 3,500 feet, is
-characteristic of the plateau grasslands, forming mats of short but
-erect stems usually less than 2 feet high. It blossoms in June and July.
-The tender young stems and yellow, fleshy fruits are browsed by
-pronghorns, and the fruits are also used by the Hopi Indians for food
-and as a seasoning. Because of its customary low-growing habit it is
-something of a hazard to hikers. It is considered the most widely
-distributed cholla in Arizona.

-
-
-Flowering in May and June and common throughout southwestern New Mexico,
-southern Arizona, and northern Mexico, the walkingstick cholla is best
-known because of its persistent clusters of yellow fruits. These remain
-throughout the winter, giving persons the first-glance impression that
-the large shrubby cactus, sometimes 8 feet high, is in bloom. The fruits
-are eaten by cattle. This species is typical of desert grasslands and is
-most abundant in the open country below the edge of the oak belt in
-desert mountains. Stems of the dead plants leave a hollow cylinder of
-attractive wooden meshes when the soft tissues decay, and are favored
-for making canes, as the stem is long and straight, hence the name
-walkingstick cholla.

-
-
-Also called "sun-drops," these plants are particularly welcome because
-they bloom early in the springtime. Many species of evening-primrose are
-large flowered, abundant along roadsides and sandy flats, and notably
-fragrant. White-flowered species are more common, but there are several
-with yellow flowers. Blossoms open at night and begin to wilt, turning
-pink during the following day. These are among the handsomest of desert
-plants and during favorable years make a spectacular spring display,
-sometimes growing with goldpoppies and sandverbenas to produce a riot of
-color.

-
-
-Common to all of the deserts crossed by the boundary between the United
-States and Mexico, ocotillo (oh-koh-TEE-yoh) is a spectacular shrub, its
-many long, stiff, green-barked and thorn-guarded stems bearing at their
-tips clusters of bright red flowers from April to June. Following rains,
-the stems cover themselves with clusters of bright green leaves. When
-drought comes these leaves are shed, to be renewed again after another
-rain. This procedure may be repeated half a dozen times in one year.
-Cahuilla Indians eat both flowers and seeds, and make a beverage by
-soaking the blossoms in water. When planted as hedgerows the thorny
-wands make an impenetrable fence.

-
-
-Also known as "wild morning glory," this naturalized perennial has
-become a serious agricultural pest throughout the Southwest. In
-California it is considered the State's worst weed. Once established,
-its deep root system spreads widely, sending up shoots that grow rapidly
-with climbing, vine-like stems and morning glory-like white to pink
-flowers that bloom from May to July. In the desert it is usually found
-on road shoulders, where it makes an attractive display. The name
-_convolvulus_ comes from the Latin and means "to entwine." A
-blood-clotting substance has been found in this plant.

-
-
-Usually found in desert mountain ranges, at elevations between 5,000 and
-6,000 feet, this ground-hugging, herbaceous perennial blossoms in May
-and June. Flowers are larger than those of the several other desert
-species of phlox, most of which have longer flower stems and vary in
-color from white to purple.

-
-
-More commonly known as "gilia" in honor of the eighteenth-century
-Italian botanist Felippo Luigo Gilii, the many species of gilias are
-common and widespread throughout the deserts of the Southwest at nearly
-all elevations. Since the flowers are usually small and range in color
-from white to lavender, pink, and yellow, they are not as well known as
-more spectacular genera. Some are annuals but there are also many
-perennial species. Starflower is found from west Texas and Chihuahua to
-western Arizona at elevations from 1,000 to 8,000 feet on dry plains and
-mesas, especially on limestone soils. It blossoms from March to October.

-
-
-Known also as "scorpionweed" and "wild heliotrope," phacelia is a
-handsome plant with coarse foliage, somewhat hairy and sticky. Among
-other plants it often grows to a height of 18 inches, but on dry, open
-desert flats is usually much shorter. Flowers, which may be found from
-February to June, are sweet scented, but the foliage has a disagreeable
-odor. _Crenulata_, which is one of many species, grows from New Mexico
-and southern Utah throughout Arizona to Lower California. It is
-conspicuous among the spring-blooming flowers of the desert. The curling
-flower heads which bear some resemblance to the erect tail of a scorpion
-are responsible for the name "scorpionweed."

-
-
-In favorable years these ground-hugging plants form broad, colorful
-mats, but in dry seasons these annuals may be tiny, each with a single
-flower almost as large as the rest of the plant. Flowering from February
-to May, bloom is heaviest in March and April. This species, also called
-"purplemat," is common on flat, sandy, open desert soils from
-southeastern California and Baja California to southeastern Arizona at
-elevations below 3,500 feet. Because of its low-growing habit, nama
-requires that you lie prone to examine it closely, hence is one of the
-many small desert herbs called "bellyflowers."

-
-
-Believed to be the original host of the Colorado potato beetle, this
-annual is a pest on rangelands because of its spine-covered stems and
-fruits. Spines are long, straight, sharp, and straw-colored. It is
-common on desert plains and mesas at elevations from 1,000 up to 7,000
-feet, blooming from June to August. The leaves and unripe fruits of this
-and several other species are reportedly poisonous, as they contain an
-alkaloid, solanin.

-
-
-Also known as "white horse-nettle," "bull-nettle" and "trompillo,"
-silverleaf nightshade is a showy plant when in blossom May to October
-along roadsides and in open fields at elevations from 1,000 to 5,500
-feet from Kansas and Colorado to Arizona, California, and south to
-tropical America. It is an agricultural pest in irrigated areas,
-difficult to eradicate. Pima Indians used the crushed fruits as an
-additive to milk in making cheese. A close relative, _Solanum jamesii_
-is known as wild-potato as it produces small tubers eaten by desert
-Indians.

-
-
-One of the really striking flowers of the deserts and mesas, the large,
-showy, trumpet-shaped blossoms and broad, dark green leaves of the
-datura or "western jimson" arouse the curiosity of persons seeing them
-for the first time. Quite common along roadsides below 6,000 feet from
-California to Texas and Mexico, the white blossoms remain open at night
-but close and droop soon after sunrise. The summer-blooming plants often
-grow in large clumps with buds, flowers, and maturing fruits all present
-at the same time. Indians used the plants for various medicinal
-purposes, a dangerous practice, since all parts of the plant contain
-various alkaloids, including atropine. Roots are narcotic and were
-sometimes eaten by Indians to induce visions.

-
-
-Sometimes growing to a height of 10 or 12 feet, the graceful swaying
-branches of tree tobacco bear at their ends clusters of tubular,
-greenish-yellow blossoms 2 to 3 inches long. The leaves contain the
-alkaloid anabasine, which is poisonous to livestock. Leaves of the
-closely related and much smaller desert tobacco, _Nicotiana
-trigonophylla_, contain nicotine and have long been smoked by desert
-Indians. The plant is still so used on ceremonial occasions. _Nicotiana_
-was named for Jean Nicot, French ambassador to Portugal, who introduced
-tobacco to France about 1560.

-
-
-Although restricted in its range to the Chihuahuan Desert, ceniza,
-sometimes called silverleaf, is so spectacular when in blossom that it
-invariably attracts attention and arouses interest. The small, abundant,
-ash-gray leaves give this 3- to 4-foot shrub a distinguished appearance
-throughout the year, but when it suddenly bursts into bloom, usually in
-September, it becomes a thing of rare beauty. It is so sensitive to
-moisture that it may blossom a few hours after a soaking rain, which
-gives rise to the popular belief that it can forecast wet weather and in
-consequence it is sometimes called "barometer bush."

-
-
-Penstemons, or "beard-tongues," of various species are numerous on the
-desert as well as throughout the higher, moister parts of the Southwest.
-This one blooms in spring and early summer below 6,000 feet from
-southwestern New Mexico to southern California. It, and the similar
-Parry Penstemon, are among the more noticeable desert species because of
-their showy flowers covering the clumps of erect stems two to four feet
-tall. Both are fairly common on mesa slopes and mountain canyons with
-individuals well scattered, hence not contributing to the mass flower
-displays of the desert springtime.

-
-
-Known in southern California as "scented penstemon" because of its
-fragrance, this regal "beardtongue" comes to the height of bloom in May.
-However, it may be found in flower from March to September. When the
-tall, flower-covered stems grow in abundance, as often occurs in
-gravelly washes at elevations between 3,500 and 6,500 feet, the sight is
-remarkable. This species prefers limestone soils in both the
-Mojave-Colorado and Sonoran Deserts. The sweet nectar attracts bees.

-
-
-Paintedcups, or "Indian paintbrushes" as they are more widely known, are
-found from desert lowlands to snow-capped mountain tops. _Castilleja
-linariaefolia_ is the State flower of Wyoming. The northwestern
-paintbrush, known in southern California as "desert paintbrush," has an
-extremely wide range. The flash of red among other desert plants is
-actually due to the brightly colored floral bracts, as the flowers
-themselves are small and inconspicuous. This species blossoms in early
-spring in rocky or gravelly locations between 2,000 and 7,000 feet, on
-dry plains and hillsides.

-
-
-Owl-clover is one of the short-stemmed desert spring annuals which, in
-favorable seasons, carpet the desert floor with a beautiful, colorful
-mass display. Sometimes growing in pure stands, at others mixed with
-goldpoppies, lupines, or other spring flowers, it is found throughout
-southern Arizona, southern California, and Baja California, at
-elevations between 1,500 and 4,500 feet, blossoming from March to May.
-Cattle and sheep graze it extensively. The Spanish name _escobita_ means
-"little broom." Individual flowers are not conspicuous, but their
-clusters intermixed with the colorful bracts produce a pretty, feathery
-effect.

-
-
-More properly called "desert catalpa," this tall shrub or small tree, 6
-to 15 feet high, has willow-like leaves, spreading branches, and a
-short, crooked, black-barked trunk. The violet-scented flowers usually
-appear from April to August, often after the start of summer rains. They
-are replaced by long, slender seed pods that remain dangling from the
-branches for months. Mexicans make from the dried flowers a tea that
-they believe has considerable medicinal value. Desert-willow is usually
-found along desert washes below 4,000 feet from west Texas to southern
-California and northern Mexico. It is frequently cultivated as an
-ornamental because of its attractive orchid-like flowers.

-
-A glossy-leafed shrub with golden, trumpet-shaped flowers, the
-trumpet-bush blooms from May to October on dry, rocky hillsides between
-elevations of 3,000 and 5,000 feet. It is not common, but occurs from
-western Texas through southern New Mexico and Arizona southward into
-tropical America. Trumpet-bush is cultivated as an ornamental in
-southern parts of the United States and in Mexico. The roots are used
-medicinally and in making a beverage. Stems and leaves contain small
-quantities of rubber. The shrubs, which occasionally reach a height of 6
-feet, are browsed by bighorn sheep and probably by deer.

-
-
-Lacking chlorophyll and parasitic on the roots of bur-sage and other
-desert composites, broomrape is so unusual in appearance as to attract
-immediate attention. Although fairly common in low-elevation deserts
-from west Texas and Mexico to southern California, it is occasionally
-found as far north as southern Utah and Nevada and at elevations up to
-7,000 feet. The rather inconspicuous flowers appear from February to
-September. Navajo Indians made a decoction of the plant as a treatment
-for sores. Desert Indians ate the tender stems in springtime.

-
-
-Restricted to western Arizona, southern California, and Lower
-California, _palmata_ has similar-appearing relatives with much wider
-distribution. Their large leaves and vine-like growth attract attention
-along roadsides at elevations up to 7,000 feet. Most widespread of these
-strikingly coarse perennials is _Cucurbita foetidissima_, the
-buffalo-gourd or calabazilla. This rank-growing, ill-smelling vine-like
-plant may have prostrate stems up to 20 feet long. The globular fruits,
-of tennis ball size, were cooked by Indians or dried for winter
-consumption. Seeds were boiled to form a pasty mush. California pioneers
-used the crushed roots as a cleansing agent in washing clothes, but
-found that particles clinging to the cloth were a skin irritant.

-
-
-Common throughout the Southwest, particularly on overgrazed rangelands
-and deserted clearings, this plant, also called "matchweed" or
-"turpentine-weed," often occurs in almost pure stands. The resinous
-stems burn readily, throwing off black smoke. Most abundant on dry hills
-and mesas, 3,000 to 6,000 feet elevation, this perennial is found from
-1,000 to 7,000 feet, blossoming from June to October. Bees obtain nectar
-and pollen from the small but densely crowded, yellow flower clusters.
-The many stiff, upright branches cause some plants to appear almost
-globular in shape and a foot to 2 feet in diameter. Plants of this genus
-are reported as poisonous to sheep and goats if eaten in quantity, but
-are apparently unpalatable, as they are rarely grazed.

-
-Also known as "desert daisy" and "rock daisy," this dwarf winter annual
-grows on sandy or stony mesas at elevations below 3,500 feet, blossoming
-from February through April. The short stems spread to form a mat or
-rosette, 5 or 6 inches across, growing flat on the sand, and ornamented
-with many small flowers, each set off by a small cluster of leaves.
-Desertstar grows principally in southern Arizona and southern
-California, but has been recorded from southern Utah and Sonora, Mexico.

-
-
-Varying in color from violet and lavender to almost white, flower heads
-of the Mohave aster are numerous, sometimes as many as 20 simultaneously
-in bloom on one plant. This ornamental perennial prefers dry, rocky
-slopes below 6,000 feet in southern Utah, Nevada, western Arizona, and
-southeastern California. Characterized by silvery foliage and large
-flower heads, the Mohave aster is well worthy of cultivation and does
-well in hot, dry locations. Flowers appear from March to May, but with
-the coming of summer heat the stems and leaves become twisted, brown,
-and unattractive.

-
-
-By no means limited to the deserts, fleabane is common throughout the
-Southwest, including parts of Mexico. In some localities it is known as
-"wild-daisy." Six to 15 inches tall, with attractive circular flowers,
-fleabane often forms noticeable patches along road shoulders and on dry
-open slopes, blossoming from February to October. Flowers may be an inch
-in diameter in springtime, but those in summer are usually smaller. The
-name arises from an ancient belief that the odor of some species
-repelled fleas.

-Locally called "desert-broom," or "Mexican broom," this species of
-baccharis is an erect, coarse, evergreen shrub 3 to 6 feet high,
-frequently encountered on hillsides and bottomlands at elevations
-between 1,000 and 5,500 feet from southwestern New Mexico to southern
-and Baja California and northern Mexico. Greening up following summer
-rains, the shrubs blossom from September to February. Flowers are
-inconspicuous, but the fruits develop as masses of spectacular cottony
-threads, giving the shrubs a snow-covered appearance. Among some Indian
-tribes the twigs are chewed to relieve toothache. In Mexico the shrub is
-called _hierba del pasmo_.

-
-
-From 3 inches to a foot high, desert zinnia is a dwarf shrub with small,
-stiff, dull green leaves and attractive, four-petaled flowers that are
-present from April to October. Preferring clayey or rocky, arid soils at
-elevations 2,500 to 5,000 feet, this species is found from west Texas to
-southern Arizona and Mexico. Although related to the garden zinnia,
-which is a native of Mexico, only the large flowered desert species,
-_Zinnia grandiflora_, is considered worthy of cultivation.

-
-
-Sometimes blossoming as early as November and often lingering until May,
-brittle-bush is a dome-shaped, winter-flowering bush that brings delight
-to desert dwellers in Nevada, Arizona, southern California, and
-northwestern Mexico. Stems of the low-growing, silvery-leaved shrub
-exude a gum which was chewed by desert Indians and burned as incense by
-priests in mission churches, giving the plant the local name,
-_incienso_. Strictly a desert shrub, about 3 feet high, brittle-bush
-prefers rocky hillsides below 3,000 feet. Growing in masses it often
-covers entire slopes with a mass of golden bloom, contributing to the
-early spring flower display. Bighorn sheep are reported to rely on this
-species for browse.

-meet, the "giant sunray," as it is sometimes called, is spectacular
-rather than beautiful. Coarse and weedy, the large clusters of silvery
-leaves and long stemmed, sunflower-like blossoms that appear from April
-to June invariably attract attention and stimulate curiosity. An even

-
-
-Although it is reported from elevations up to 7,000 feet, golden
-crown-beard is usually found at much lower levels from Kansas south to
-Texas, California, and northern Mexico. Sometimes growing in clusters,
-single plants are also common as a weed of roadsides and waste ground.
-The all-yellow, sunflower-like blossoms are widespread in the desert
-from April to November. Desert Indians and early pioneers are said to
-have used the plant to treat boils and skin diseases. The Hopis soaked
-the plants in water in which they bathed, to relieve the pain of insect
-bites.

-
-
-Also called "tickseed," wild coreopsis is closely related to cultivated
-ornamentals of the same name. The desert species inhabits open locations
-at elevations between 1,500 and 2,500 feet in southern Arizona, southern
-California, and Baja California. Plants usually bloom between February
-and May. The closely related _Coreopsis bigelovii_ is a southern
-California annual having somewhat larger flowers, up to 2 inches in
-diameter, with orange centers. Flower stems are naked, with the leaves
-clustered at their bases.

-                            91. Paperflower
-
-
-At its best in sandy desert soil, paperflower is a compact, shrubby
-plant about 1 foot high, with tangled branches. When fully developed it
-is symmetrically globular in outline. It prefers mesas and desert plains
-at elevations between 2,000 and 5,000 feet from western New Mexico to
-southern California and northern Mexico, flowering throughout the year
-but most abundantly in springtime. Sometimes called "paper-daisy," the
-flowers are persistent, fading to straw color and turning papery with
-age. They may remain on the stems for weeks.

-                           92. Desert baileya
-
-
-Commonly called "desert marigold," baileya blossoms in all seasons, most
-heavily from March to November, and is one of the better known flowers
-of the Southwest. Each circular blossom occupies the tip of a foot-high
-stem. Plants usually have a thrifty, garden-variety appearance. They are
-common along roadsides and on well-drained, gravelly slopes up to 5,000
-feet from west Texas to southeastern California and Chihuahua. The large
-flower heads are showy and the species is cultivated in California.
-Cases are on record of sheep and goats on overgrazed ranges being
-poisoned by eating this plant.

-
-
-Covering vast stretches of open desert with a carpet of yellow bloom
-following wet winters, goldfields is an appropriately named spring
-flower found at elevations below 4,500 feet. The low-growing plant
-produces small but attractive blossoms on mesas and plains, March to
-May, from central and southern Arizona to California, and Baja
-California. Horses graze _Baeria_ avidly, but are annoyed by a small fly
-that frequents the fragrant blossoms, giving the plant the name "fly
-flower" in some localities.

-                             94. Chaenactis
-
-
-Probably because it is one of the attractive white desert flowers,
-chaenactis is popularly called "morning bride." A larger,
-yellow-flowered species, _Chaenactis lanosa_, found on the California
-deserts, is called "golden girls." Both are spring flowering annuals
-and, in common with other members of the genus, sometimes called
-"pincushion plants." "Morning bride" is often found growing about the
-bases of creosotebushes, thriving at elevations between 1,000 and 3,500
-feet in southern Nevada, western Arizona, and southeastern California.

-
-
-Rarely considered beautiful, the groundsels are common and widespread,
-and are readily recognized by the untidy appearance of the large flowers
-which are sometimes almost 2 inches in diameter. The rather delicate,
-stringy foliage is sometimes covered with cottony threads. One species
-is called "ragwort." Douglas groundsel is a shrubby plant sometimes as
-much as 3 feet high, common in sandy washes and on dry foothill slopes.
-It occurs from southern Utah and Arizona to California and Mexico,
-between 1,000 and 6,000 feet. At lower elevations these plants bloom at
-almost any time of year.

-
-
-Everyone recognizes the thistles with their prickly leaves and stems,
-and large flowers ranging in color from white to lavender, pink and
-purple. Several species grow in the deserts, the New Mexico species
-being widespread at elevations from 1,000 to 6,000 feet in Colorado and
-Nevada south through New Mexico and Arizona to California, blossoming
-from March to September. Navajo and Hopi Indians are reported to use
-thistles medicinally. The nectar of some species is eagerly sought by
-hummingbirds.

-
-
-A very attractive plant, desert dandelion has several flower stalks from
-a few inches to a foot tall. Some of the blossoms may be nearly 2 inches
-in diameter. This annual is common in open, sandy basins, where it is a
-conspicuous contributor to the spring flower spread, blooming from March
-through May in the creosotebush belt of Arizona and southern California.
-It has been reported from as far north as Idaho and Oregon. Sometimes a
-single plant has 10 or 12 flower heads in blossom at the same time.

-
-
-There are many species of malacothryx native to the western and
-southwestern United States. Some are locally called "desert dandelion,"
-"snake's head," "yellow saucers," and "cliff aster." _Fendleri_ is one
-of the smaller species, with stems only 4 or 5 inches long, rising from
-a rosette of bluish-green leaves. Blooming from March to June, this
-delicate relative of the common dandelion covers with its pale yellow
-flowers rocky slopes and sandy plains and mesas, at elevations between
-2,000 and 5,000 feet from West Texas to western Arizona.

-
-
-Also called "tackstem" because of the numerous dark-colored, tack-shaped
-glands protruding from the stem, this white-flowered, branching annual
-blossoms from March to May at elevations of 500 to 4,000 feet. It is a
-conspicuous item of the spring flower display from west Texas to
-southern California and northern Mexico. A similar species with yellow
-flowers, _Calycoseris parryi_, common at elevations around 3,000 feet,
-blooms in March and April. It is found in southwestern Utah, Arizona,
-and southern California.

-
-
-Naturalized from Europe and generally considered a weed, sowthistle is
-found in waste grounds and along roadsides from near sea level to 8,000
-feet. It blossoms from February to August, the flowers becoming cottony
-seed heads as conspicuous as the blooms. A close relative, _Sonchus
-oleraceus_, which blossoms from March to September, produces a gum from
-the drying of the sap, reportedly a powerful cathartic. It has also been
-used as a treatment for persons suffering from the habitual use of opium
-derivatives.

-
-1.F.1. Project Gutenberg volunteers and employees expend considerable
-effort to identify, do copyright research on, transcribe and proofread
-works not protected by U.S. copyright law in creating the Project
-Gutenberg-tm collection. Despite these efforts, Project Gutenberg-tm
-electronic works, and the medium on which they may be stored, may
-contain "Defects," such as, but not limited to, incomplete, inaccurate
-or corrupt data, transcription errors, a copyright or other
-intellectual property infringement, a defective or damaged disk or
-other medium, a computer virus, or computer codes that damage or
-cannot be read by your equipment.
-
-1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
-of Replacement or Refund" described in paragraph 1.F.3, the Project
-Gutenberg Literary Archive Foundation, the owner of the Project

-

-Defect you cause.
-
-Section 2. Information about the Mission of Project Gutenberg-tm
-
-Project Gutenberg-tm is synonymous with the free distribution of
-electronic works in formats readable by the widest variety of
-computers including obsolete, old, middle-aged and new computers. It
-exists because of the efforts of hundreds of volunteers and donations
-from people in all walks of life.
-
-Volunteers and financial support to provide volunteers with the
-assistance they need are critical to reaching Project Gutenberg-tm's
-goals and ensuring that the Project Gutenberg-tm collection will
-remain freely available for generations to come. In 2001, the Project
-Gutenberg Literary Archive Foundation was created to provide a secure
-and permanent future for Project Gutenberg-tm and future
-generations. To learn more about the Project Gutenberg Literary
-Archive Foundation and how your efforts and donations can help, see
-Sections 3 and 4 and the Foundation information page at
-www.gutenberg.org
-
-
-
-Section 3. Information about the Project Gutenberg Literary Archive Foundation
-
-The Project Gutenberg Literary Archive Foundation is a non profit
-501(c)(3) educational corporation organized under the laws of the
-state of Mississippi and granted tax exempt status by the Internal
-Revenue Service. The Foundation's EIN or federal tax identification
-number is 64-6221541. Contributions to the Project Gutenberg Literary
-Archive Foundation are tax deductible to the full extent permitted by
-U.S. federal laws and your state's laws.

-
-Section 4. Information about Donations to the Project Gutenberg
-Literary Archive Foundation
-
-Project Gutenberg-tm depends upon and cannot survive without wide
-spread public support and donations to carry out its mission of
-increasing the number of public domain and licensed works that can be
-freely distributed in machine readable form accessible by the widest
-array of equipment including outdated equipment. Many small donations
-($1 to $5,000) are particularly important to maintaining tax exempt
-status with the IRS.
-
-The Foundation is committed to complying with the laws regulating
-charities and charitable donations in all 50 states of the United
-States. Compliance requirements are not uniform and it takes a
-considerable effort, much paperwork and many fees to meet and keep up
-with these requirements. We do not solicit donations in locations
-where we have not received written confirmation of compliance. To SEND
-DONATIONS or determine the status of compliance for any particular
-state visit www.gutenberg.org/donate
-
-While we cannot and do not solicit contributions from states where we
-have not met the solicitation requirements, we know of no prohibition
-against accepting unsolicited donations from donors in such states who
-approach us with offers to donate.
-
-International donations are gratefully accepted, but we cannot make
-any statements concerning tax treatment of donations received from
-outside the United States. U.S. laws alone swamp our small staff.
-
-Please check the Project Gutenberg Web pages for current donation
-methods and addresses. Donations are accepted in a number of other
-ways including checks, online payments and credit card donations. To
-donate, please visit: www.gutenberg.org/donate
-
-Section 5. General Information About Project Gutenberg-tm electronic works.
-
-Professor Michael S. Hart was the originator of the Project
-Gutenberg-tm concept of a library of electronic works that could be
-freely shared with anyone. For forty years, he produced and
-distributed Project Gutenberg-tm eBooks with only a loose network of
-volunteer support.
-
-Project Gutenberg-tm eBooks are often created from several printed
-editions, all of which are confirmed as not protected by copyright in
-the U.S. unless a copyright notice is included. Thus, we do not
-necessarily keep eBooks in compliance with any particular paper
-edition.
-
-Most people start at our Web site which has the main PG search
-facility: www.gutenberg.org
-
-This Web site includes information about Project Gutenberg-tm,
-including how to make donations to the Project Gutenberg Literary
-Archive Foundation, how to help produce our new eBooks, and how to
-subscribe to our email newsletter to hear about new eBooks.

-<p>If your interest in desert flowers includes a desire to obtain beautiful photographs
-of them, the following &ldquo;tips&rdquo; may be helpful.</p>
-<p class="tb">MOTION is a major hazard in still photography, and flowers, especially those on
-long, slender stems, seem to be constantly in motion stimulated by the ever-present
-desert breeze. The practical solution to this problem is to take your photographing
-jaunts, if possible, in the early morning when the air is most likely to be motionless.
-A flower picture blurred by motion is a complete flop!</p>
-<p>Except for motion, nothing will irritate you more often than the abrupt, frequent,
-and marked CHANGES IN LIGHTING due to small clouds passing over
-the sun. Again, early morning has an advantage in normally cloudless desert skies.
-Clouds may be expected after 10 o&rsquo;clock on many days.</p>
-<p class="tb">DEPTH OF FIELD is highly important in flower photography, and you will be
-gratified with the results if you take pains to have all parts of the picture, except
-the background, in sharp focus. This desirable objective has become less difficult
-to attain with the advent of &ldquo;faster&rdquo; films which enable you to use the required
-small diaphragm &ldquo;stop&rdquo; without too greatly reducing the shutter speed, and still
-obtain adequate exposures.</p>
-<p class="tb">Too many flower photographers fail to get really CLOSE UP PICTURES. A
-single blossom or a small cluster of blossoms provides a much more attractive and
-significant picture than an entire plant. One blossom with, perhaps, a bud, one
-fruit, and a trace of foliage, if well composed, is tops among flower pictures. This
-objective requires camera equipment with the ability to focus on objects close to
-the lens. Also it complicates the goal of getting all parts of the picture into sharp
-focus.</p>
-<p class="tb">UNCLUTTERED BACKGROUNDS are a &ldquo;must&rdquo; in flower pictures. You might
-consider joining the flower photographers who carry with them plain gray or variously
-tinted background cards or light-weight boards. Such a card or board of
-contrasting color, when placed behind the blossom, will accomplish wonders in
-giving prominence to the flower. One method of obtaining a dark background is
-to ask someone (if you are a contortionist you can do it yourself) to stand in such
-a position as to cast a shadow on the ground or foliage behind the subject. The
-sky makes an excellent background, and you will find it useful whenever you can
-set your camera below the level of the subject.</p>
-<p class="tb">With the foregoing points in mind, study the pictures in this booklet with the
-aim of trying to surpass them in quality. By exercising care and patience, you should
-be able to do so.</p>
-<h2 class="center" id="c2"><span class="h2line1"><i>Introduction</i></span></h2>
-<h3 id="c3"><i>The Desert</i></h3>
-<p>When Webster defined a desert as a &ldquo;dry, barren region, largely treeless and
-sandy&rdquo; he was not thinking of the 50,000 square mile Great American Desert of
-the southwestern United States and northern Mexico. Most of it is usually dry and
-parts may be sandy, but as a whole, it is far from barren and treeless. Heavily vegetated
-with gray-green shrubs, small but robust trees, pygmy forests of grotesque
-cactuses and stiff-leaved yuccas, and myriads of herbaceous plants, the desert, following
-rainy periods, covers itself with a blanket of delicate, fragrant wildflowers.
-Edmund C. Jaegar, author of several books on deserts, reports that the California
-deserts alone support more than 700 species of flowering plants.</p>
-<p>The late Dr. Forrest Shreve, for many years Director of the Desert Laboratory
-of the Carnegie Institution near Tucson, Arizona, defined a desert as &ldquo;a region of
-deficient and uncertain rainfall.&rdquo; He divided the Great American Desert into four
-major sections: (1) <i>Chihuahuan</i> (chee-WAH-wahn), including the Mexican States
-of Chihuahua and Coahuila (coa-WHEE-lah), southwestern Texas, and south-central
-New Mexico; (2) <i>Sonoran</i>, including Baja California, southwestern Arizona, and
-northwestern Sonora; (3) <i>Mojave</i> (moh-HAH-vee), Colorado, including south-eastern
-California and extreme southern Nevada; (4) <i>Great Basin</i>, including Nevada,
-Utah, southwestern Idaho and southeastern Oregon.</p>
-<p>Since the steppes and mesas of the Great Basin Desert have generally lower
-temperatures, higher elevations, and greater precipitation than the other three sections,
-we are not including its flowers in this work.</p>
-<h3 id="c4"><i>Why and When Do Deserts Bloom?</i></h3>
-<p>The Great American Desert produces, when conditions are favorable, a gorgeous
-exhibition of wildflowers. Trees, shrubs, and herbs all contribute to the splendor of
-the display. Soil composition, slope and exposure, suitable temperatures, and adequate
-moisture are essential to plant growth and flower production.</p>
-<p>Moisture is the uncertain factor, and years may pass without enough rainfall to
-stimulate plant growth. Rain of less than 0.15 inch is wasted as far as desert plants
-are concerned, for the moisture evaporates before penetrating the soil. Some annuals
-produce seeds having water-soluble germination inhibitors in their coverings, hence
-fail to sprout, even after rain, unless the moisture totals at least half an inch.</p>
-<p>When soil moisture from December and January rainfall is enough to support
-potential plants it dissolves the seed coats, and the desert floor is soon carpeted with
-eager green seedlings. When winter rains are scant, as is so often the case, the
-dormant seed population fails to germinate and the spring flower display doesn&rsquo;t
-appear. There is no sure way to forecast a spectacular blossom year, for a sudden
-cold wave or period of drying winds may literally nip in the bud a potential season
-of brilliant bloom. A great flower year may occur only once in a decade.</p>
-<div class="pb" id="Page_3">3</div>
-<p>Perennials are more dependable than annuals, since some of them, particularly
-cactuses and other succulents, have water storage tissues in their stems or roots.
-These perennials may be counted on to blossom each year, but with much less
-abandon than after winters of above normal precipitation. Many perennials have
-surprisingly extensive root systems.
-Fascinating are the ways by which plants manage to thrive under severe conditions
-of desert heat and drought. As we have seen, most annuals lie dormant as seeds
-until suitable moisture and temperature occur. Then they grow very rapidly, to bloom
-and mature seeds while the soil still has moisture. Winter rains produce spring-blooming
-ephemerals, and summer showers produce summer &ldquo;quickies.&rdquo;</p>
-<p>Another group of plants, including the ocotillo (oh-koh-TEE-yoh), slows down
-life processes to become dormant during dry periods, even to dropping all leaves.
-When rains come they put on new leaves, several times a year if necessary.</p>
-<p>Cactuses and other succulents gorge themselves with water when the soil is wet,
-releasing moisture very sparingly from storage tissues during the &ldquo;long dry.&rdquo; Some
-have discarded or reduced foliage, or have covered leaf surfaces with varnish or wax,
-to decrease to a minimum the loss of vital moisture through transpiration.</p>
-<h3 id="c5"><i>Identifying Desert Wildflowers</i></h3>
-<p>Unless you are a botanist, identification of flowers by measuring and counting
-their various parts, as described in technical keys, is generally too complicated to be
-practical. Several years ago, recognizing this problem, I authored a book, <i>Flowers of
-the Southwest Deserts</i>, illustrated by Jeanne R. Janish and published by the Southwestern
-Monuments Association, designed to aid the wildflower fancier in plant
-identification by color-grouping the flowers. With Mrs. Janish&rsquo;s superb illustrations
-pointing out each plant&rsquo;s most obvious characteristics, it has proved an excellent field
-guide. However, the demand for natural color flower portraits could not go unheeded,
-and this book is the result. The two books complement each other, although each
-fills a need in its own right. Used together, they make you more positive of some
-identifications.</p>
-<p>Probably the best way to become acquainted with a flower is to be introduced
-to it by someone. But there is one catch to this method&mdash;one plant may be known
-by many aliases.</p>
-<p>When the Spaniards came into the Southwest over 400 years ago they found
-Indians had names for some flowers in their own languages. The Spaniards added their
-names, and later the Americans added English names. Some of these names were of
-similar-appearing but quite different flowers they had known &ldquo;back East.&rdquo; Later,
-scientists studied the desert plants, and gave them all Latin names.</p>
-<p>To assist in standardizing names of desert flowers, this booklet gives preference
-in its headings to scientific and common names found in <i>Arizona Flora</i>, by Kearney
-and Peebles, Second Edition, 1960. Common names found in <i>Texas Plants, A Checklist
-and Ecological Summary</i>, 1962, by F. W. Gould, also have been used. In addition,
-placed within the text, are some of the more widely used common names that we have
-encountered. Tree names, both common and scientific, follow the <i>Checklist of Native
-and Naturalized Trees of the United States</i>, by Elbert L. Little, Jr., 1953.</p>
-<p>There are many desert flowers, some quite common, for which there was not
-space in this booklet. If you wish to broaden your acquaintance to include more, we
-recommend, for added reading publications listed in the back.</p>
-<p>The author wishes to express here sincere thanks to Mrs. Pauline M. Patraw,
-Santa Fe botanist, for assistance in identifying many of the flowers pictured here. For
-assistance in checking identifications, the author is indebted to Miss Barbara Lund,
-Park Naturalist, National Park Service; to Dr. Charles T. Mason, Jr., Curator of the
-Herbarium, University of Arizona Tucson; and to Dr. W. B. McDougall, Curator of
-Botany, Museum of Northern Arizona, Flagstaff.</p>

-throughout the Southwest. This yellow-green,
-stringy-stemmed shrub with tiny,
-scale-like leaves, is usually 3 to 4 feet tall, but
-sometimes reaches a height of 12 feet. Its
-small, fragrant, springtime flowers grow in
-dense clusters that attract insects. Some species
-provide winter forage for cattle and are
-said to be browsed by bighorn sheep. Pioneers
-brewed a palatable drink from the dried
-stems. Certain Indian tribes considered the

-heads appear from July to October and create
-a spectacular mass display. The horizontal
-rootstalks interlock, crowding out other
-plants. A single rootstalk may extend 30 feet.
-The straight, hollow stems served Indians as

-to 2 feet tall, with a bud cluster at its tip.
-The delicately fragrant flowers may appear
-in late February, with some tardy bloomers

-The slender stem is not erect, like other mariposas, of which there are many species,
-but wanders over the ground or makes its twisting way among the branches of low
-shrubs. It grows at elevations up to 4,000 feet on slopes and benches of mountains
-of the Mojave-Colorado Desert, in the Death Valley area, and in the desert mountains
-of southern Arizona, blossoming during April and May. Indians and pioneers

-<p>Common throughout the Southwest, the many species of yuccas (YUH-kuhs)

-of its height (maximum 30 feet) and the fact that its roots contain saponin,
-soaptree yucca or <i>palmilla</i> (pahm-EE-yah&mdash;&ldquo;little palm&rdquo;) belongs in the narrow-leaf
-group. From southwestern Arizona across southern New Mexico, and from west
-Texas southward into the Mexican states of Chihuahua and Sonora, this spectacular
-plant blossoms in May and June on desert grasslands from 2,000 to 6,000 foot elevations.
-Cattle eat the young flower stalks, and Indians used the leaf fibers for making

-indicator. Blossoms, which do not open as wide as those of other species, grow in
-tight clusters at the tips of the branches, appearing in March and April. Joshuas do
-not blossom every year, the interval between flowerings depending upon rainfall

-Some of the larger species may require 10 to
-20 years to store enough plant food to produce
-the sturdy, fast-growing flower stalk.
-After blossoming, the exhausted plant dies.
-<i>Agave scabra</i>, one of the spectacular forms, is

-throughout much of the year, but most profusely
-in April and May. Fuzzy white, globular
-fruits are almost as spectacular as the
-flowers. The plant can endure long periods of
-drought. Following rains its foliage gives off
-a musty, resinous odor, suggestive of creosote,
-stimulating the Mexican name <i>hediondilla</i>
-(little stinker). In Mexico the plant is considered
-to have medicinal values and many
-uses. The Pima Indians boiled the leaves,

-1.F.
-
-1.F.1. Project Gutenberg volunteers and employees expend considerable
-effort to identify, do copyright research on, transcribe and proofread
-works not protected by U.S. copyright law in creating the Project
-Gutenberg-tm collection. Despite these efforts, Project Gutenberg-tm
-electronic works, and the medium on which they may be stored, may
-contain "Defects," such as, but not limited to, incomplete, inaccurate
-or corrupt data, transcription errors, a copyright or other
-intellectual property infringement, a defective or damaged disk or
-other medium, a computer virus, or computer codes that damage or
-cannot be read by your equipment.
-
-1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
-of Replacement or Refund" described in paragraph 1.F.3, the Project
-Gutenberg Literary Archive Foundation, the owner of the Project
-Gutenberg-tm trademark, and any other party distributing a Project
-Gutenberg-tm electronic work under this agreement, disclaim all
-liability to you for damages, costs and expenses, including legal

-receive a refund of the money (if any) you paid for it by sending a
-written explanation to the person you received the work from. If you
-received the work on a physical medium, you must return the medium
-with your written explanation. The person or entity that provided you
-with the defective work may elect to provide a replacement copy in
-lieu of a refund. If you received the work electronically, the person

-without further opportunities to fix the problem.
-
-1.F.4. Except for the limited right of replacement or refund set forth

-remaining provisions.
-

-Defect you cause.

-Section 2. Information about the Mission of Project Gutenberg-tm
-
-Project Gutenberg-tm is synonymous with the free distribution of

-Gutenberg Literary Archive Foundation was created to provide a secure
-and permanent future for Project Gutenberg-tm and future

-The Foundation is committed to complying with the laws regulating
-charities and charitable donations in all 50 states of the United
-States. Compliance requirements are not uniform and it takes a
-considerable effort, much paperwork and many fees to meet and keep up
-with these requirements. We do not solicit donations in locations
-where we have not received written confirmation of compliance. To SEND
-DONATIONS or determine the status of compliance for any particular
-state visit www.gutenberg.org/donate
-
-While we cannot and do not solicit contributions from states where we
-have not met the solicitation requirements, we know of no prohibition
-against accepting unsolicited donations from donors in such states who
-approach us with offers to donate.
-
-International donations are gratefully accepted, but we cannot make
-any statements concerning tax treatment of donations received from
-outside the United States. U.S. laws alone swamp our small staff.
-
-Please check the Project Gutenberg Web pages for current donation
-methods and addresses. Donations are accepted in a number of other
-ways including checks, online payments and credit card donations. To
-donate, please visit: www.gutenberg.org/donate

-Section 5. General Information About Project Gutenberg-tm electronic works.
-
-Professor Michael S. Hart was the originator of the Project
-Gutenberg-tm concept of a library of electronic works that could be
-freely shared with anyone. For forty years, he produced and
-distributed Project Gutenberg-tm eBooks with only a loose network of
-volunteer support.
-
-Project Gutenberg-tm eBooks are often created from several printed
-editions, all of which are confirmed as not protected by copyright in
-the U.S. unless a copyright notice is included. Thus, we do not
-necessarily keep eBooks in compliance with any particular paper
-edition.
-
-Most people start at our Web site which has the main PG search
-facility: www.gutenberg.org
-
-This Web site includes information about Project Gutenberg-tm,
-including how to make donations to the Project Gutenberg Literary
-Archive Foundation, how to help produce our new eBooks, and how to
-subscribe to our email newsletter to hear about new eBooks.
