Part 16

There are many kinds of Streptanthus, difficult to distinguish, smooth plants, often with a "bloom"; stems branching; leaves often clasping at base, the lower ones usually more toothed or lobed than the upper. The flowers are very peculiar in shape, not like most Mustards, but suggesting the shape of a Bleeding Heart flower; the sepals usually colored like the petals, two or all of them bulging at base, so that the calyx is broad below and contracted above; the corolla regular or irregular, the petals purple or white, with claws and narrow, wavy or crisp borders; the stamens four long and two short, or in three unequal pairs, the longest pair often united below; the pods long, narrow, flattish or cylindrical, on a broad receptacle; the seeds flat and more or less winged. These plants are called Jewel-flower, but the name does not seem particularly appropriate.

Wild Candytuft--Thlaspi glaucum.]

Nothing about this odd-looking plant is pretty and it almost seems as if it were trying to make up by eccentricity for its lack of beauty. It is common in dry, sandy places in the mountains and our attention is first attracted to the tall, branching stalks, because they are strung with such queer-looking leaves. In summer the upper ones are bright-yellow or dull-purple and they clasp the stem and curve over, so that they look like small brass shields, pierced by the stem. There are three or four of these curving leaves, very smooth and shiny, and several more below, which are flatter and dark-green, and the stem, from six inches to three feet high, is oddly twisted and leans to one side. The small flowers are yellowish or mauve, veined with purple, less than half an inch long and peculiar in shape. The contrast in color between the flowers and leaves is very odd and very ugly, but as if this were not enough, later in the season the curious thing hangs itself with ridiculously long, slender pods, like great hooks, and looks queerer and more disheveled than ever.

Prettier and not so queer-looking as the last. The leaves are arrow-shaped, clasping at base, rather leathery, bluish-green, with a "bloom" and tinged with purple on the backs, the lower ones toothed, and the pods are about two inches long, flat and tinged with purple. The flowers are half an inch long, pearly-white, the petals yellowish, veined with purple, and are quite pretty. This grows in dry places.

Shield-leaf--S. tortuosus.]

There are only a few kinds of Stanleya, all western; tall, stout, smooth perennials, or biennials, with a "bloom"; flowers large, mostly yellow, without bracts, in long, terminal, clusters; sepals long, narrow; petals long, narrow, with long claws; stamens six, very nearly equal; ovary on a short stalk, with a short style or none; pods long, narrow and flattish, with long stalks; seeds numerous. Named for Lord Edward Stanley, President of the Linnaean Society.

The pretty common name of this tall, handsome plant was given by Helen Hunt Jackson and the long, feathery wand of numerous blossoms is beautiful and suggests a plume. On the other hand, the straggling flowers have such long, narrow, curling petals, the threadlike filaments look so much like curling antennae and the long, thin pods stick out so awkwardly, like insects' legs, from among the flowers on the lower part of the stalk, that we find the general effect is rather weird and spidery. In fact the plant I drew had a large yellow spider, precisely the color of the flowers, half-concealed among them. The stem is from two to five feet high; the leaves are smooth, pale bluish-green, the lower ones with leaflets and a leaf-stalk, and the flowers are bright-yellow, or cream-color, about an inch across. This grows usually in dampish spots, in arid regions. The picture is of one I found in Indian Garden Canyon, a branch of the Grand Canyon.

The only kind, a fine plant, well worth cultivation; smooth and branching, about two feet tall, with handsome, bluish-green leaves, with a "bloom," the root-leaves with long, purplish leaf-stalks and sometimes nine inches long; the flowers half an inch across, with a lilac-tinged calyx and white petals, prettily toothed, forming a pretty, rather flat-topped cluster. The pods are very slender, nearly straight, one or two inches long. This grows among rocks, in protected situations, and is not common. Only a few, separate flowers are given in the picture, as the plant I found, near the Desert Laboratory at Tucson, was almost out of bloom.

Golden Prince's Plume--Stanleya pinnatifida.]

There are a good many kinds of Lesquerella, all American; low plants, more or less hairy or scurfy; flowers mostly yellow, in clusters; petals without claws; pods roundish, more or less inflated, and giving the common name, Bladder-pod, also used for Isomeris arborea.

Pretty little plants, often growing in quantities among rocks in mountain canyons. The slender stems are from a few inches to over a foot tall, springing from a cluster of root-leaves, varying a good deal in shape, dull-green and harsh to the touch. The flowers are half an inch or more across, with white petals, often tinged with pink, with a little yellow in the throat, and form a pretty, rather flat-topped cluster.

In desert places, such as the terrible sandy wastes of the Petrified Forest, where it seems a miracle that anything should grow, we find the close, pale, gray-green tufts of this little plant, crowned with racemes of small bright-yellow flowers. The small, thickish leaves are long, narrow and white with close down, the stems, about three inches high, branch at the root and the little pods are tipped with a style of about their own length. L. Gordóni, of Arizona, also has clusters of little yellow flowers, often covering sandy hillsides with bright color; the leaves slightly stiff and rough, the pods much inflated. It resembles L. purpurea in general form and size.

There are many kinds of Brassica, coarse "weeds" in this country. This is the ancient Latin name for Cabbage, which belongs to this genus, as well as Cauliflower, Turnip, and Brussels Sprouts.

A European "weed," common everywhere. In California it grows to an enormous height, sometimes twelve feet, and when in bloom is a beautiful feature of the landscape, covering the fields with a shimmering sheet of pale gold. The leaves are dark-green, smooth or with a few hairs, all with leaf-stalks, the lower leaves large and jagged, cut into leaflets, the upper leaves mostly toothless. The fragrant flowers form long clusters, each flower about three-quarters of an inch across; the small, cylindrical pods stand erect, close to the branching stem. A valuable, antiseptic oil is made from the black, pungent seeds, exported from California by the ton.

CAPER FAMILY. Capparidaceae.

The flowers of this family are much like the Mustards, but the stamens are all of equal length and are often more than six; the leaves are alternate and consist of three or several leaflets, with stalks, and the plant usually tastes bitter and disagreeable instead of pungent. There is no partition in the pods, which are on long, threadlike stalks; the ovary is superior and the seeds are kidney-shaped. Many flowers have only a rudimentary pistil and never produce fruit. The Caper, of which we eat the pickled flower-buds for a relish, is a shrub which grows in the Levant. The family is quite large and flourishes in warm regions.

There are several kinds of Cleomella, resembling Cleome, except that the pods are different.

This is a handsome, rather odd-looking plant, with a stout, smooth, yellowish or purplish stem, sometimes branching and over a foot tall. The leaves are bright light-green, smooth, toothless and slightly thickish, and the three leaflets are sometimes each tipped with a hair, and have a tuft of small hairs at the base of the leaf-stalk, in place of a stipule. The flowers are about half an inch across, and are a beautiful warm shade of golden-yellow, the long stamens being of the same color and giving a very pretty feathery appearance to the large cluster. The pods are queer-looking little things and stick straight out from the stem. This has a slightly unpleasant smell, but looks very gay and pretty in the fields and along the edges of the mesas around Reno.

There are many kinds of Cleome; ours are branching herbs, with palmately-divided leaves; the flowers with four sepals, four petals, and six stamens. The ovary has a stalk with a gland at its base and becomes a long pod, with a long stalk and many seeds.

In Arizona this exceedingly handsome plant often covers the dry beds of rivers with acres of beautiful color. The smooth, branching stem is sometimes as much as eight feet high. The upper leaves are long and narrow and the lower are larger and usually have three leaflets, but all are bluish-green and peculiarly soft and smooth to the touch. The buds are purple and the delicate flowers, with threadlike flower-stalks, grow in a handsome, feathery cluster, sometimes a foot long, with numerous bracts. They have four, pinkish-lilac or white petals and six exceedingly long, threadlike stamens with minute, curling, green anthers. The lilac pistil is also very long and before the flower drops off begins to develop into a small, flat, green pod. These gradually lengthen, until the stem is ornamented with many hooklike pods, with slender stalks, hanging all along it. Many of the flowers do not produce fruit. The foliage when it is crushed gives off a rank, unpleasant smell, which is responsible for the local name of Skunk-weed. This is widely distributed and is found in the central and northern part of the United States, as well as in the Southwest.

An odd-looking plant, with very pretty, feathery flower-clusters. The hairy stem is over a foot tall and the leaves are bright yellowish-green and mostly smooth on the upper side, with hairy margins and hairy on the under side. The flowers are a warm shade of bright golden-yellow and form a handsome, rather flat-topped cluster, with long stamens, and the oblong pods are an inch long or less, flat and much broader than those of the last. The flowers are slightly sweet-scented and the whole plant exudes a faint unpleasant odor. This is conspicuous on the dreary mesas around Reno, often growing with Cleomella longipes, which it very much resembles in general appearance, except for the pods, which are quite different.

There is only one kind of Isomeris.

This is a shrub about three feet high, which is attractive except for its unpleasant smell. The leaves are smooth, toothless, stiffish and thickish, and bluish-green, with a small bristle at the tip, and mostly with three leaflets. The pretty flowers are nearly an inch across and warm yellow in color, not very bright but pretty in tone, with six very long, yellow stamens, and form a short, oblong cluster. The ovary has such a long stalk, even in the flower, that it gives an odd appearance and it develops into a very curious and conspicuous, drooping pod, an inch and a half long, much inflated and resembling a very fat pea-pod, on a long stalk, with two rows of seeds like little peas inside it, which taste very bitter. This is quite common on southern mesas. The name Bladderpod is also used for Lesquerella, which belongs to the Mustard Family.

ORPINE FAMILY. Crassulaceae.

A rather large family, widely distributed; odd-looking, mostly very succulent herbs, with smooth, fleshy leaves and stems, without stipules; flowers in clusters; sepals, petals, pistils, and stamens, all of the same number, usually four or five, sometimes the stamens twice as many; ovary superior; receptacle with honey-bearing scales, one behind each pistil; pistils separate, developing into small dry pods, containing few or many, minute seeds. Some of these plants look like tiny cabbages and we are all familiar with their tight little rosettes in the formal garden-beds of hotels and railway stations, where they are so stiff and unattractive that we hardly recognize them when we find them looking exceedingly pretty in their natural homes. The Latin name means "thick."

There are many kinds of Sedum, no one kind very widely distributed; fleshy herbs; leaves usually alternate; flowers star-like, often in one-sided clusters; stamens and pistils sometimes in different flowers on different plants; sepals and petals four or five; stamens eight or ten, on the calyx, the alternate ones usually attached to the petals; styles usually short. The Latin name means "to sit," because these plants squat on the ground, and Stonecrop is from their fondness for rocks.

This makes beautiful golden patches, on dry slopes or more or less open hilltops, usually among limestone rocks. The reddish stems are from six to ten inches tall, the leaves are rather long and narrow, thick but flat, forming pretty pale-green rosettes, more or less tinged with pink and yellow, and the pretty starry flowers are three-quarters of an inch across, bright-yellow, with greenish centers, the stamens giving a feathery appearance.

On moss-covered rocks, moistened by the glistening spray blowing from the Yosemite waterfalls, we find these beautiful plants, covering the stones with a brilliant, many-colored carpet. The flowers are stars of brightest gold, about half an inch across and delicately scented, and form flat-topped clusters, three or four inches across. The upper part of the stalk, which is about six inches tall, and the upper leaves are delicate bluish-green, but both stem and leaves shade to vivid scarlet at the base. Spreading out on the ground from the base of the stem in all directions are numerous little runners, each bearing at the end a small rosette of thick, blue-green leaves, forming a beautiful contrast to the vivid color of flowers and stems. The leaves and runners are very brittle and break off at a touch.
