BIRTHWORT FAMILY. Aristolochiaceae
ОглавлениеA rather small family, chiefly of warm countries, but widely distributed; herbs or shrubs; the leaves alternate or from the root, with leaf-stalks, more or less heart-shaped, without stipules; the flowers perfect, mostly large, symmetrical or irregular in form, with or without a corolla; the calyx with three or six lobes, or irregular; the stamens six to many, inserted on the pistil; the ovary wholly or partly inferior; the fruit a mostly six-celled capsule, containing many seeds.
There are several kinds of Asarum.

The handsome leaves of this perennial are its conspicuous feature. They have long, hairy leaf-stalks and are heart-shaped and toothless, from three to five inches broad, dark rich green, prettily veined and often also beautifully mottled with white, smooth on the upper surface and hairy on the under. We notice them immediately in the damp, dark woods they live in, but unless we look carefully we miss the single, large, strange, purplish-brown flower, the color of dead leaves, which nestles close to the ground as if trying to hide itself. This has twelve stamens, with stout filaments, and six styles, united at the base. There are no petals, but the hairy calyx has three lobes, which are sometimes an inch and a half long, and have long points like tails. The seed-vessel is roundish, crowned by the withered calyx and stamens. The rootstock cannot be used as a substitute for ginger, but smells and tastes very aromatic and pungent. This resembles the Wild Ginger of the East, but is handsomer.
