LOASA FAMILY. Loasaceae

Not a very large family, all but one natives of America; herbs, armed with hooked, stinging or sticky hairs; without stipules; the flowers perfect, with five sepals and five to ten petals; the stamens numerous, with threadlike filaments, the outer ones sometimes petal-like, inserted with the petals on the throat of the calyx and usually arranged in clusters opposite the petals; the ovary inferior, with a threadlike style; the capsule crowned with the calyx-lobes.

There are many kinds of Mentzelia, all western, often with white shining stems and alternate leaves; the calyx cylindrical or top-shaped, with five lobes; the petals five or ten; the styles three, somewhat united. The barbed hairs which clothe the stems and leaves make the plant stick to whatever it touches, probably helping to distribute the seeds, hence the common name Stick-leaf.

Blazing Star

Mentzèlia laevicàulis

Yellow

Summer, autumn

West, except Wash. and Ariz.

A stout, branching biennial, two to over three feet tall, with shining white stems, almost smooth, long, rather narrow, wavy-toothed leaves and enormous flowers, in clusters of two or three at the ends of the branches and opening only in bright sunlight. They are from three to five inches across, with five, broad, light yellow petals and quantities of very long stamens, making a beautiful center. Five of the stamens have broadened filaments, resembling narrow petals, the style is three-cleft, and the capsule is oblong, containing many flat, winged seeds. These plants usually grow in dry stream-beds and are not rare, but through various accidents I have never been able to secure a drawing of either this or the next.

Blue Violet – V. adunca var. longipes.

Johnny Jump-up – Viola pedunculata.

Evening Star

Mentzèlia Líndleyi

Yellow

Summer

California

A more slender plant than the last, with magnificent flowers, two and a half inches across, which open in the evening and remain open during the following morning. They have five, broad petals, with pointed tips, bright golden-yellow, colored with vermilion at the base, and handsome yellow centers. The filaments are very slender, some of the outer ones slightly broadened at base, and the style is not cleft. This grows in the mountains. There is a drawing of it in Miss Parsons's Wild Flowers of California. It is called Buena Mujer, or Good Woman, by the Spanish Californians, because the leaves stick so tightly to one.

Mentzèlia multiflòra

Yellow

Spring

Southwest, Utah, etc.

An odd-looking plant, with very pale, straggling stems and thickish leaves, a pretty shade of pale green, all exceedingly disagreeable to touch. The buds are tipped with salmon-color and the flowers are an inch and a half to two inches across, with a long green calyx-tube with buff lobes, ten petals, bright yellow inside and pale buff outside, and pretty, fuzzy, yellow centers. They open in the evening, about five o'clock, and the plant would be pretty, in spite of its harsh foliage, if more of the flowers were out at one time. This is common along roadsides in the Southwest and in New Mexico and Colorado.

Mentzèlia gracilénta

Yellow

Spring

Southwest

This has several pale greenish or pinkish stems, from a few inches to a foot and a half tall, which look smooth but are very harsh to the touch, springing from a cluster of stiff, harsh, dull-green leaves, variously lobed or toothed. The flowers are nearly an inch across, with glossy, bright yellow petals and beautiful, fuzzy, yellow centers, and are very delicate and pretty.

Mentzelia multiflora.

M. gracilenta.

ROCK-ROSE FAMILY. Cistaceae

A rather large family, mostly of the Mediterranean region; herbs or low shrubs; flowers regular, perfect, all the parts borne on the receptacle; sepals five, the two outer ones smaller and bract-like, or lacking; petals three to five; stamens many; ovary superior, one-celled, with a single style, or none; fruit a capsule, with several or many seeds.

There are many kinds of Helianthemum, widely distributed, perennials; leaves alternate, undivided, toothless; flowers yellow and, in most North American species, of two sorts; the earlier ones with large, yellow petals, very numerous stamens and a many-seeded pod; the later ones, small, clustered, with small petals or none, three to ten stamens, and small, few-seeded pods.

Rock-rose

Heliánthemum scopàrium

Yellow

Spring

California

A pretty plant, with many, slender stems and narrow, yellowish-green leaves, forming clumps from one to two feet high. The flowers are half an inch to three-quarters of an inch across, the buds and calyxes reddish and the petals clear yellow, the pistil greenish, with a three-lobed stigma. In favorable situations, such as Point Loma, this makes attractive little bushes, neat yet feathery, suggesting large clumps of grass, sprinkled thickly with flowers.

CACTUS FAMILY. Cactaceae

A large family, nearly all natives of America and of dry or desert places, with strange characteristics, which make them easily recognized as a whole, but many of the individuals have not yet been studied or described; fleshy plants, with thick stems, often flattened, ridged or covered with knobs, mostly without leaves, usually with spines, which generally protrude from cushions of small bristles; the flowers perfect, regular, showy, and mostly single; sepals, petals, and stamens all numerous; ovary inferior, with a long style and several stigmas; fruit usually a pulpy berry, containing many seeds.

There are many kinds of Echinocactus, round or oval plants, mostly ribbed, with bunches of spines of several kinds, arranged in straight or spiral rows; the fruits scaly, though spineless.

Rock-rose – Helianthemum scoparium.

Barrel Cactus, Bisnaga

Echinocáctus Wislizèni

Yellow, reddish

Summer

Southwest

A common and useful kind, the shape and often the size of a barrel, covered with spines. The Indians cut off the top of the plant and pound the pulp with a stick into a soft mass, which they squeeze with their hands, extracting a large amount of watery juice, which is wholesome and not unpalatable and has often saved lives in the desert. Indians use the spines for fish-hooks, hence a common name, Fishhook Cactus, and the celebrated cactus candy is made from it. The flowers are large.

There are many kinds of Echinocereus, oblong or cylindrical, spiny plants, generally a few inches tall, usually growing in clumps; stems ridged, or with spiny ribs; fruits spiny.

Hedgehog Cactus

Echinocèreus Polyacánthus

Red

Spring

Ariz., New Mex. Tex.

This forms a clump of several stems, each about the shape and size of a cucumber, and armed with bunches of long, stiff spines. The flowers are two or three inches long, with deep red petals, dull pink anthers, and a bright green pistil. This grows in the Grand Canyon.

There are many kinds of Opuntia, with jointed stems, cylindrical or flattened, armed with bristles, usually with spines. The fruits and fleshy joints are good for fodder, if the spines are removed, and hence there has been much inquiry into the economic value of these plants. It has been found that the spiny species are the most valuable for fodder, under extremely arid conditions, as the spines can be burned off, while the unarmed forms are subject to the attacks of so many animals that a crop cannot be secured without the protection of fences. The spines are removed either by singeing the growing plant with a torch, or the upper parts are cut off and thrown into a fire, or sometimes the plants are made into fodder by being chopped up, spines and all, in a machine. The Prickly Pears in Sicily and the Orient came from America.

Opúntia acanthocàrpa

Yellow

Spring

Southwest

From three to six feet tall, resembling Cholla, with long, cylindrical joints and whitish spines. The pretty flowers are about two inches long, with orange-yellow petals and an ivory-white pistil. The fruits are spiny and become dry when ripe. This grows in the desert around Needles.

Hedgehog Cactus – Echinocereus polyacanthus.

Opuntia acanthocarpa.

Cholla

Opúntia fúlgida

Red

Spring, summer

Arizona

A horrible shrub, or dwarf tree, four to six feet high, with a thick trunk and several, spreading, contorted branches, with cylindrical joints, twisting in awkward ways. The trunk and larger limbs are brownish-gray, starred with dead, dry spines, but the twigs are pale bluish-green, covered thickly with stars of pale-yellowish spines, each an inch or so long, with a barbed tip. From the numerous magenta flowers strange, yellowish, cup-shaped fruits develop, seeming to spring one out of the other in a haphazard way, hanging in long chains, awkward but rather ornamental, and remaining on the plants for several years without change, except that they grow slightly larger. The distant effect of this plant is a pale, fuzzy mass, attractive in color, giving no hint of its treacherous character – more like a wild beast than a plant! The joints suggest a very ferocious chestnut-burr and break off at a touch, thrusting their spines deeply into the flesh of the unwary passer-by, so that the Indian story, that this plant flings its darts at wayfarers from a distance, might almost as well be true, and the barbs making the extraction difficult and painful. The ground under the plants is strewn with fallen joints, which take root and propagate themselves. Small animals pile these around their holes for defense, several kinds of birds build in the thorny branches and are safe from enemies, and the fruits, being spineless and succulent, are valuable for fodder, so the Cholla is not entirely malevolent. The name is pronounced Choya. There are many similar kinds, some with very handsome rose-like flowers, others with bright scarlet fruits. They are curious and interesting inhabitants of the desert.

Prickly Pear

Opúntia basilàris

Pink

Spring

Arizona

Low plants, with no main stem, with spreading, flattened branches, the joints of which are flat disks, resembling fleshy, bluish-green leaves. These disks are half an inch to an inch thick and six inches long, more or less heart-shaped, sprouting one out of the other, at unexpected angles. The beautiful flower is about three inches across, like a tissue-paper rose, pale or very deep pink, with a whitish pistil, yellow anthers, and crimson filaments. The joints have a strong fishy smell, when cut, and are dotted with tufts of small, brown bristles, exceedingly unpleasant to get in one's fingers. This is rare and grows at the Grand Canyon. Prickly pears usually have yellow flowers and long spines.

Spring, summer

Southwest

There are fifty or more common kinds of Prickly Pear, many of them as yet undescribed and little known. They have flattened joints and yellow flowers, like the one illustrated, which is typical, often measuring three or four inches across, the petals variously tinted outside with salmon, rose, and brown.

There are many kinds of Cactus, round, cylindrical, or oval plants, covered with knobs, bearing clusters of spines, those of some species having hooked tips. They may be known by their smooth fruits, without scales or spines.

Pincushion Cactus

Cáctus Gràhami (Mamillaria)

Pink

Spring

Arizona

A quaint little plant, often no bigger than a billiard ball, with long, blackish, hooklike spines, projecting from stars of smaller spines. The flowers are pink and the berries are smooth, fleshy fingers of brightest scarlet, edible, pretty and odd. Sometimes we see one of these prickly little balls peeping from under a rock and again we find them growing in a colony, looking much like a pile of sea-urchins. This grows in the Grand Canyon, and there are similar kinds in southern California.

There are many kinds of Cereus, with cylindrical or oval stems, from a few inches to forty feet tall, not jointed, with ribs or rows of knobs, running lengthwise, and clusters of spines.

Column Cactus, Sahuaro

Cèreus gigantèus

White

Spring, summer

Arizona

These tree-like plants are wonderfully dignified and solemn in aspect, with none of the grotesque or ferocious effect so common among their relations. They grow in numbers on the mountain slopes around Tucson and are easily recognized by their size and very upright form, rearing their thick, cylindrical branches straight up in the air, to a height of thirty or forty feet. They are smooth and light green, armed with rows of spines in stars along the ridges, and ornamented during May and June with handsome, large, whitish, wax-like flowers, very perfect in form, opening in the daytime, blooming most abundantly on the sunny side of the plant and remaining open but a short time. Woodpeckers often make holes for nests in the branches, which are used afterwards by a little native owl, the smallest kind in the world, and by honey-bees, and these holes often lead to decay and to the ultimate death of the tree. The fruits, with crimson flesh and black seeds, are valued by the Papago Indians for food, and mature in enormous quantities in midsummer, but birds eat up many of the seeds and of the millions reaching the ground only a very few germinate and develop into odd, little round plants, a few inches high, often eaten by some animal before they become sufficiently prickly for protection.

Pincushion Cactus – Cactus Grahami.

Common Prickly Pear – Opuntia.

EVENING PRIMROSE FAMILY. Onagraceae

A large family, widely distributed, most abundant in America; herbs, with no stipules; flowers usually perfect, their parts usually in fours; calyx-tube attached to the usually four-celled, inferior ovary and usually prolonged beyond it; stamens four or eight, inserted with the petals, on the throat of the calyx-tube, or on a disk; style single with a four-lobed or round-headed stigma; fruit usually a four-celled capsule, containing small seeds or a nut. The flowers are generally showy and many are cultivated.

Eulòbus Califórnicus

Yellow

Spring

Southwest

This is the only kind of Eulobus. It would be a pretty plant, if more flowers were out at one time and if they did not close so soon. The smooth, hollow, loosely-branching stem is from one to three feet tall, with a "bloom," the leaves are smooth, rather light dull-green, and the buds are erect. The flowers are about three-quarters of an inch across, with a very short calyx-tube, light-yellow petals, fading to reddish-pink, eight stamens, four of them smaller and shorter, and the light-green stigma with a round top. The slender pods are three inches long, smooth, cylindrical, and turning stiffly down, with many seeds. This grows in mountain canyons.

Eulobus Californicus.

There are a few kinds of Chamaenerion; perennials, often woody at base; leaves alternate; flowers in clusters, perfect, slightly irregular, white or purplish; petals four; stamens eight; style threadlike, with a four-cleft stigma; capsule long, four-sided, containing numerous seeds, tipped with a tuft of hairs. The calyx-tube is not prolonged beyond the ovary, which chiefly distinguishes this genus from Epilobium.

Fire-weed, Great Willow-herb

Chamaenèrion angustifòlium (Epilobium)

Purple, pink

Summer

Across the continent

A striking and decorative perennial, from two to six feet tall, with alternate leaves, pale on the under side, the veins making a scalloped border near the margin, the upper leaves and stems sometimes slightly downy, and the drooping buds deep reddish-pink or purple. The flowers form a fine cluster, with small bracts, each flower an inch or more across, the sepals often pink or purple and the petals bright purplish-pink; the stamens drooping, with purplish anthers; the style hairy at base, the capsule two or three inches long. This is very common, both East and West, reaching an altitude of ten thousand feet, and often growing in such quantities in the mountains as to cover large tracts with bright color. The seeds are furnished with tufts of white, silky hairs, making the plant very conspicuous when gone to seed, covering it with untidy bunches of pale down and giving a strange shaggy effect. It often flourishes in places that have been burned over, hence the name Fire-weed, and Willow-herb is from the leaves and the silky down on the seeds, suggestive of willows.

Water Willow-herb

Chamaenèrion latifòlium (Epilobium)

Magenta

Summer

Northwest

This grows in wet places; the flowers are larger and handsomer than the last, but it is not so tall. The stems are stout, reddish, and branching, from six to eighteen inches high, both stem and leaves with a "bloom," and the leaves are thickish, bluish-green on the upper side and paler yellowish-green on the under, sometimes toothed, with no veined border. The buds are deep-red and the flowers form a handsomer cluster, shorter than the last, with leafy bracts, each flower from one to over two inches across, with reddish-pink sepals, deep-red outside, and magenta petals veined with deeper color, sometimes notched, one petal longer than the others; the anthers purplish; the pistil drooping and purplish, with a smooth style. This plant is also covered with tufts of white down when gone to seed. The contrasting purples and reds of the flowers give a very vivid effect, set off by the bluish-green foliage, especially when growing among the gray rocks of moraines, watered by icy glacier streams. It reaches an altitude of ten thousand feet, growing in the East and in Europe and Asia.

Water Willow-herb – Chamaenerion latifolium.

Fire-weed – C. angustifolium.

There are many kinds of Epilobium, differing from Chamaenerion chiefly in the calyx-tube, which is prolonged beyond the ovary.

Willow Herb

Epilòbium Franciscànum

Pink

Spring

Northwest

A perennial, not especially pretty, with a stout, reddish stem, from one to three feet tall, slightly downy above, and dull green leaves, mostly smooth and the lower ones opposite. The flowers are less than half an inch across, with bright or pale, purplish-pink petals, deeply notched and not spreading. This grows in wet spots around San Francisco.

There are several kinds of Gayophytum; differing from Epilobium in the capsule and seeds, and easily distinguished from them by the hairy buds; leaves alternate, long, narrow, and toothless; flowers small; petals four, white or pink, with very short claws; stamens, with swinging anthers, eight, four shorter and usually sterile; capsule club-shaped. The species are difficult to distinguish, because of the smallness of the flowers.

Gayophýtum eriospérmum

White

Summer

Cal., Oreg.

A delicate little plant, with smooth, purplish stems, exceedingly slender branches, dull green leaves, and pretty little flowers, an eighth of an inch to half an inch across, white, with a little yellow in the center, fading to pink. This grows in sandy soil, at rather high altitudes, in Yosemite.

Willow-herb – Epilobium Franciscanum.

Gayophytum eriospermum.

There are numerous kinds of Godetia, variable and difficult to distinguish, not yet fully understood by botanists, all western and mostly Californian, with narrow, alternate leaves and handsome flowers, which close at night. They have four petals and resemble Onagra, but the flowers are never yellow and the anthers are not swinging, but fixed to the tips of the filaments by their bases; also resembling Clarkia, but the petals are without claws. The calyx is often colored, tube more or less funnel-form, lobes turned back, or more or less united and turned to one side; stamens eight, unequal, the shorter ones opposite the petals; style threadlike; stigma with four, short lobes; capsule four-sided, or cylindrical, mostly ribbed, rather leathery, splitting open, with four valves, containing many seeds. These plants bloom in late spring, hence the pretty name, Farewell-to-Spring.

Farewell-to-Spring

Godètia defléxa

Pink

Summer

California

A branching plant, woody at base, two feet high, with smooth stems; smooth, toothed leaves; nodding buds and large handsome flowers. The petals are pale-pink, about an inch long, the pistil pink, and at a distance the effect of the flower is much like a Mallow. As is usual with Godetias, the sepals are stuck together and stand out at one side, giving the flower a quaint effect of having thrown back a little hood in order to look about. This grows in light shade.

Farewell-to-Spring

Godètia quadrivúlnera

Pink, lilac

Spring, summer

Northwest

This is common in the foothills of the Sierras and Coast Ranges and has a slender stem, about a foot tall, with more or less downy leaves, sometimes slightly toothed, and a few very pretty flowers, about an inch and a half across, with bright lilac-pink petals, usually splashed with carmine. This red spot gives a vivid effect and the delicate flowers look exceedingly gay and charming, as they sway in the wind among tall grasses on open hillsides.

Godètia Góddardii var. capitàta

Pink

Spring, summer

California

From one to two feet tall, with a rather stout, more or less branching stem and soft, rather downy, dull green leaves. The flowers are about an inch across, with purplish-pink petals, often stained with crimson at the tips. This is found on dry hills in the Coast Ranges.

Farewell-to-Spring – G. deflexa.

G. Goddardii var. capitata.

Godetia quadrivulnera.

Godètia vimínea

Purplish-pink

Summer

Northwest

A handsome plant, with nearly smooth, slender, reddish stems, a few inches to two feet tall, and smooth, pale-green, toothless, narrow leaves, mostly without leaf-stalks. The buds are erect and the flowers form a long, loose cluster, with bright purplish-pink petals, half an inch to over an inch long, with a large, magenta blotch near the center, or at the tip, and yellowish at base; the stamens and pistil all purple; the calyx-lobes not caught together, but turned primly back. This forms fine patches of bright color in rather meadowy places in Yosemite and elsewhere in the Sierra Nevada foothills. G. Dudleyàna is pretty and slender, with drooping buds and light lilac-pink flowers, the petals paler at base, with darker dots, the calyx-lobes caught together and turned to one side, and also makes beautiful patches of color on sunny slopes around Yosemite.

There are several kinds of Clarkia, resembling Godetia, but the petals have claws. The stems are brittle; the leaves mostly alternate, with short, slender leaf-stalks; the buds nodding; the flowers in terminal clusters, with four petals, never yellow, and four sepals, turned back; the stamens eight, those opposite the petals often rudimentary; the stigma four-lobed; the capsule long, leathery, erect, more or less four-angled, with many seeds. Named in honor of Captain Clarke, of the Lewis and Clarke expedition, the first to cross the Rocky Mountains to the Pacific, in 1806.

Clarkia

Clàrkia élegans

Pink

Spring, summer

California

A conspicuous plant, on account of the oddly contrasting colors of the flowers, and very variable both in size and smoothness. It grows from six inches to six feet high; the stems more or less branching; the leaves sometimes toothed and often reddish; the buds and calyxes often woolly. The flowers are very gay; the sepals being dark red or purple, the petals, with long, slender claws, bright pink and the anthers scarlet! The stamens, four long and four short, have a hairy, reddish scale at the base of each filament, the anthers of the shorter stamens often white, and the capsule is usually curved, with no stalk, nearly an inch long, often hairy. When the foliage is red, as it often is, the various combinations of red in the flowers and leaves are quite startling. This is common in the foothills of the Sierra Nevada and Coast Ranges and is often rather shabby looking, but in favorable situations is very handsome.

Godetia viminea.

Clarkia elegans.

Clarkia

Clàrkia rhomboídea

Purple

Spring, summer

Northwest, Nev., Utah

Pretty and delicate and not nearly so conspicuous as the last, with a slender, smooth, branching stem, one to three feet tall, with smooth leaves, mostly alternate, nodding buds, and a few pretty flowers, about three-quarters of an inch across. The sepals are reddish-yellow; the petals pinkish-purple, often dotted with purple at base, with a short, broad, toothed claw; the stigma magenta; the filaments purple, with a whitish, hairy scale at the base of each; the anthers grayish, all perfect; the capsule four-angled, slightly curved, about an inch long. This grows in the foothills of the Sierra Nevada and Coast Ranges and is widely distributed in Yosemite, but nowhere very abundant.

Pink Fairies

Clàrkia pulchélla

Pink

Summer

Northwest

Odd and exceedingly charming flowers, with very slender, very slightly downy, purplish, branching stems, from six inches to a foot tall, and smooth leaves. The flowers are fantastic in form, the airiest and most fairy-like blossoms that can well be imagined, over two inches across, their delicate petals with long, toothed claws and three lobes, bright rose-pink, shading to a deeper tint at the base, the calyx slightly downy and reddish. Four of the stamens are perfect and four are rudimentary; the anthers are reddish; the pistil white; the capsule an inch long, eight-angled, with a spreading stalk. It is a pretty sight to see these gay flowers dancing in the wind on open mountain slopes. C. concínna (Eucharidium), of the Coast Ranges, is similar, equally beautiful and even more brilliant in coloring; the flowers sometimes in such quantities as to make patches of bright pink color, very effective when growing among yellow Sedums, Scarlet Larkspurs, and scarlet Indian Pinks, in shady mountain canyons.

Clarkia rhomboidea.

Pink Fairies – C. pulchella.

There are several kinds of Sphaerostigma; leaves alternate; flowers yellow, white or pink, turning green or reddish; stamens eight, with oblong, swinging anthers; style threadlike, with a round-top stigma; capsule four-celled, usually long and narrow, four-angled, often twisted, with no stalk.

Evening Primrose

Sphaerostígma bistórta (Oenothera)

Yellow

Spring

California

A common kind, very variable in its manner of growth, being tall and erect in moist, shady places and spreading flat on the ground in dry, sunny spots. The leaves are dull green, more or less downy and more or less toothed, and the flowers are three-quarters of an inch across, clear yellow, usually with a speck, or blotch, of reddish-brown at the base of each petal; the stamens and pistil also yellow; the pods reddish and very much twisted. Gravelly washes are often thickly sprinkled with these gay and charming flowers.

Sphaerostígma Veitchiànum (Oenothera)

Yellow

Spring

California

Much like the last, but the flowers are only a little over a quarter of an inch across. The pods are dark red and shiny, with a few hairs.

Beach Primrose

Sphaerostígma viridéscens (Oenothera cheiranthifolia var. suffruticosa)

Yellow

All seasons

California

A beautiful seashore plant, forming large, low clumps of reclining stems and pale gray, downy foliage, the twigs and younger leaves silvery-white. The flowers are about an inch and a quarter across, clear yellow, often with two, dark red dots at the base of each petal; the stamens and pistil also yellow of the same shade; the pods pinkish, downy, and much twisted. The flat masses of pale foliage, strewn with golden disks, are exceedingly effective, growing in drifting sand hills along the coast, from San Francisco south.

S. Veitchianum.

Beach Primrose – Sphaerostigma viridescens.

White

Spring

Nevada

A queer little, stunted-looking, desert plant, with almost no stem, but with several branches, spreading flat on the ground, stiff, smooth and purplish, with crowded clusters of flowers, leaves, and pods, mostly at the ends, the whole forming flat clumps, from six to ten inches across. The leaves are smooth, slightly thickish, pale bluish-green and toothless; the buds are erect, and the flowers are over a quarter of an inch across, white, with yellow anthers and a green stigma. The pods are very much twisted and form odd little snarly bunches.

There are only a few kinds of Chylisma; the flowers in terminal clusters; the calyx with a more or less funnel-form tube and four lobes; the petals four, not notched; the stamens eight, unequal; the stigma with a round top, the capsule long, membranous, with a stalk.

Chylisma

Chylísma scapoìdea var. clavaefórmis (Oenothera)

White

Spring

Ariz., Utah

A charming desert plant, from a few inches to a foot tall, with one or more, pinkish, smooth, rather leafy stems, springing from a pretty clump of smooth, bluish-green leaves. The delicate flowers are about three-quarters of an inch across and form a graceful cluster of several or many blossoms. The petals are white or yellow, often tinted with pink, with some specks of maroon at the base, and the sepals are pinkish-yellow; the stamens pale yellow; the stigma green; the pods erect.

There are several kinds of Pachylophus; perennials, stemless or nearly so; leaves from the root; calyx downy, with a long tube; petals white or pink; stamens eight, with threadlike filaments, the alternate ones longer; style threadlike; stigma four-cleft; capsule woody.

White Evening Primrose

Pachýlophus marginàtus (Oenothera)

White

Summer

Ariz., Utah, Nev., Col.

This has a few large flowers, three inches or more across, with pure-white diaphanous petals, fading to pink, and pink calyx-lobes. The buds are erect, hairy and pink, and the flowers spring from a cluster of long, downy root-leaves, narrowing to slender leaf-stalks, with hairs on the veins and on the toothed and jagged margins, and have almost no flower-stalk, but the hairy calyx-tube is so long, sometimes as much as seven inches, that it looks like a stalk. The root is thick and woody and the capsule is egg-shaped and ribbed, with no stem. There is a patch of these wonderful flowers in the Grand Canyon on Bright Angel trail, halfway between the rim and the plateau, where in a shaded spot beside a great rock the pure blossoms seem to shed a moonlight radiance. They are equally beautiful on the dry plains of Utah, where they grow in quantities.
