CARPET-WEED FAMILY. Aizoaceae
ОглавлениеNot a very large family, mostly natives of warm regions. Ours are branching herbs, lying mostly on the ground; leaves mostly opposite or in whorls; flowers perfect; sepals four or five; petals numerous, small or none; stamens few or many, usually on the calyx; ovary sometimes superior; fruit a capsule. In this country most of this family are dull little plants, with inconspicuous flowers.
There are many kinds of Mesembryanthemum, mostly African; ours are smooth, very succulent perennials; without stipules; leaves opposite; calyx-lobes unequal and leaf-like; petals long, narrow and very numerous, inserted with the innumerable stamens on the calyx-tube; ovary with ten or twelve styles, becoming a sort of berry, containing many minute seeds, and opening at the top in rainy weather. The terribly long name is from the Greek, meaning "noonday flower."

One of the queerest looking plants that it is possible to imagine, the stout stems and large flat leaves thickly encrusted with millions of small translucent beads, resembling glass or ice and giving a glistening effect to the whole plant. They cluster especially thickly along the wavy margins and under sides of the leaves, and on the calyxes, and feel quite hard to the touch, but when they are crushed underfoot they exude a watery juice, which is said to be alkaline and injurious to shoe-leather. The stems and leaves are light bright-green, the tips and margins tinged with bright pinkish-red, especially on dry mesas, where this plant sometimes covers the ground for long distances with flat rosettes, forming a thick, red carpet, beautiful in color. In shadier, damper places, such as the crevices in the sea-cliffs at La Jolla, it becomes quite a large, tall plant, scarcely tinged with red and very glistening. The flowers are about an inch across, with a greenish center, surrounded by numerous, small, yellowish anthers and a single row of many, white or flesh-colored petals, suggesting the tentacles of a sea-anemone. In fact the whole plant is curiously suggestive of some low form of animal life. It is very troublesome to farmers in the south near the sea, and also flourishes in the Mohave Desert, in France and the Canary Islands.

A very strange and conspicuous plant, often clothing sandy slopes with a curious mantel of trailing, fleshy stems and foliage thickly sprinkled with thousands of gaudy flowers. The stems are stout and flattish, several feet long; the leaves three-sided, with flat faces, tipped with a small reddish point; the calyx-lobes three-sided like the leaves. The stems, leaves, and the calyx-lobes are all pale bluish-green with a "bloom" and exceedingly succulent, the watery juice running out in large drops when the plant is broken. The twigs seem to be fitted into a sort of socket, from which they come out very easily, so that the plant comes apart almost at a touch. The fragrant flowers are two or three inches across, bright but crude in color, the numerous, purplish-pink petals resembling the rays of a composite and encircling a fuzzy ring of innumerable stamens, with white, threadlike filaments and small, straw-colored anthers, around a dark-green center, composed of the top of the calyx and the six to ten styles of the ovary. This accommodating plant is very useful and ornamental in hot, sandy places, where not much else will grow, and may be seen hanging its long stems over the sea-cliffs all along the coast, from Patagonia to Marin County in California. It also grows in Africa and is extensively cultivated. The fruit is edible, with pulp and tiny seeds something like a fig.
