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.

Blue-eyed Grass—Sisyrinchium bellum.

ORCHID FAMILY. Orchidaceae.

A very large family, most abundant in the tropics; curious plants, with oddly beautiful flowers. Perhaps because they are also rather rare they seem to have a peculiar fascination for the public; in fact almost any strangely-shaped flower is apt to be dubbed an orchid by the passer-by. They are perennial herbs, with various kinds of roots, some of them parasitic, usually with alternate, toothless leaves, the lower ones sheathing the stem. In some kinds the leaves have dwindled to scales. The flowers are perfect, irregular, with six divisions; the three sepals are alike and colored like petals; two of the three petals are alike, but the central one differs in size and shape and is called the lip. This is conspicuously colored, often spurred, and contains nectar for the attraction of "long-tongued" insects, on which these plants depend mostly for cross-pollination. The mechanism for this purpose is curious and interesting. The stigma is usually a broad sticky surface and its style is united with the filaments and forms, in front of the lip, a column which is usually capped by a single two-celled anther, containing two clusters of pollen, one in each cell. Each cluster consists of a few waxy grains, held together by cobweb-like threads, which run together and terminate in a sticky disk. These disks adhere to the insects, which push in to get the nectar, and are transported to the gummy stigma of another flower. The inferior ovary develops into a three-valved capsule, containing numerous minute seeds. Orchis is the ancient Greek name.
