A large family, widely distributed and found throughout our continent. Perennial herbs, with bracts; the leaves long, narrow, toothless, and sheathing; the flowers showy, perfect and regular, twisted in the bud, not falling off in withering, of three and six parts; the three stamens on the base of the sepals, their anthers turning outward; the single style with three branches; the ovary inferior, becoming a three-celled, usually three-angled, many-seeded capsule. This family is noticeably distinguished from the Lily family by the inferior ovary, and from the Amaryllis family by the three stamens.

There are many kinds of Iris. To the casual observer the flowers appear to have nine petals of different sizes, but in reality there are three sepals, three petals, and three petal-like branches of the style. The three outer divisions, or sepals, are large and spread or turn down; the three inner divisions, or petals, are usually narrower and are erect; the style branches arch over and under each is a stamen. The sepals and petals have claws, which are united below and form a tube; the capsule is large and contains many, flat, black seeds, in one or two rows in each cell; the large rootstock is usually fleshy. Iris is from the Greek for "rainbow," in allusion to the variegated tints, and Flower-de-luce from the French "fleur-de-lis," or "lily-flower." Many odd and beautiful kinds are cultivated from the Old World. Orris-root is made from the roots of a Florentine species.

Western Blue Flag

Ìris Missouriénsis

Violet, blue

Spring, summer

West, except Wash, and Oreg.

A very handsome and decorative plant, growing in large clumps, in damp situations, from stout, creeping rootstocks. The stiff, sword-shaped leaves, mostly shorter than the stems, are smooth and light bluish-green and the stout stems, from one to two feet high, bear usually two, pale-violet flowers, about three inches long, emerging from thin, papery bracts. The sepals are white, or pale blue, delicately veined with violet, with a yellow-veined rib down the middle, the petals are pale blue or pale violet, veined with purple, and the buds are yellowish, veined with brown. This grows in profusion in the Yosemite meadows, at the foot of El Capitan, and is delicately beautiful, but would be more effective if the coloring were a little stronger.

Douglas Iris

Ìris Douglasiàna

Purple, lilac, cream

Spring, summer

Cal., Oreg.

A beautiful kind, very common in the Coast Ranges. It grows in patches, or singly, and has rather dark green leaves, longer than the flower-stalks, and lovely flowers, which vary exceedingly in color. Near the coast they are usually bluish-purple, but in mountain woods they run from violet and mauve to pink, yellow, and white. They are often striped with white and yellow, delicately veined with purple, and measure three or four inches across. In the redwood forests, in northern California, they are peculiarly large and beautiful, their delicate tints of cream and straw-color, tinged with mauve and marked with reddish-purple, and wonderfully set off by their dark forest background. This kind often blooms throughout the rainy season, but chiefly in early spring.

Hartweg's Iris

Ìris Hartwégi

Yellow and violet

Summer

California

This odd and pretty little Iris grows in half-dry, open forests, in the Sierra Nevada Mountains. The many flower-stems, from six to twelve inches tall, are overtopped by some of the long, narrow leaves and the flowers are from one and a half to two inches long, either yellow, veined with violet, or pale-violet, veined with purple. The two color forms often grow together and attract much attention from tourists. They look very pretty, springing from a carpet of fallen pine-needles, in the forests along the Wawona road near Yosemite.

Ground Iris

Ìris macrosìphon

Blue, purple

Spring, winter

California

A beautiful kind, forming low clumps of many, very narrow leaves, from five to twenty inches long and much taller than the flower-stalks. The handsome flowers are over three inches across, bright purplish-blue, the sepals veined with darker color and marked with a white stripe. This is common on grassy hills near the coast and farther inland becomes taller and paler in color. The flowers are slightly sweet-scented and begin to bloom in January. The Hupa Indians used the leaves for making twine and rope for their nets and snares. There are many other beautiful western Irises.

Iris Douglasiana.

There are numerous kinds of Sisyrinchium, attractive little plants, all American, many from South America; with fibrous roots; grasslike leaves; slender, flat stems, sometimes branching; papery and green bracts and pretty flowers, that soon wither, on very slender pedicels, the six spreading divisions all alike; the filaments of the stamens united; the style branches slender, the capsule roundish, containing round seeds.

Blue-Eyed Grass

Sisyrínchium béllum

Blue

Summer

Cal., Oreg.

The deep blue stars of this pretty plant are a beautiful feature of the fields near Santa Barbara, and in other parts of California, in summer; in fact they are so plentiful in some places that they are a menace to the farmers. They grow in clumps, about a foot tall, among the grass. The stems are somewhat branching, the leaves are shorter than the stem, and the bracts are about an inch long, green and sheathing. There are about seven flowers on each stem, in a loose cluster, each about an inch across and handsomer than their relations in the East. They vary in tint from bright blue to purple, with a yellow "eye," and their divisions are prettily notched at the tips, with a little prong. The anthers are arrow-shaped, the style short, with three very small stigmas, and the small, oddly-shaped, little capsule is dark-brown when ripe, and perhaps suggested one of the common names, Nigger-babies. It is called Azulea and Villela by Spanish-Californians.

Golden-Eyed Grass

Sisyrínchium Califórnicum

Yellow

Spring, summer

Cal., Oreg.

This is very much like Blue-eyed Grass, but the flowers are bright yellow, the stems are about a foot tall, broadly winged and not branching, and the leaves are somewhat broader. The pretty flowers are nearly an inch across and there are from three to seven in a cluster. The filaments are united at the base only, the style is cleft to below the middle, and the small capsule is rather oblong. This grows in swampy places near the ocean. S. Arizònicum has yellow flowers and branching stems and grows in Arizona. S. Élmeri also has yellow flowers, with purple lines, and is found in wet places in the Sierras. When pressed and dried the yellow-flowered Sisyrinchiums stain the paper reddish-purple.
