Zygadenus (Greek, yoke and gland, some of the species having two glands in the base of the perianth). Liliaceae. Smooth and somewhat glaucous perennials with non-bulbous rhizomes or with tunicate bulbs; some of the species are grown in pots, others in the open; interesting plants of secondary importance horticulturally. Leaves radical or gathered at the base of the st., long-linear, those of the st. small and few: raceme terminal, simple or paniculately branched: fls. perfect or polygamous, white, yellowish or greenish; perianth withering-persistent, spreading, the petal-like oblong or ovate sepals 1-2 glandular near the more or less narrowed but not clawed base; stamens 6, free: caps. 3-celled in fr., the cells separate at the top or for their entire length.— About 25 species have been described, one of which is Siberian, one Japanese, and the remainder from N. Amer. including Mex. The species of Zygadenus are little known in cult. They are sometimes recommended for the wild-garden, where they thrive in wet or boggy places. Increased by division; also rarely by seeds. Some or all of the species have poisonous seeds, bulbs, rhizomes, and foliage, being known as "death camas" (see Bull. No. 125, Professional Paper, U. S. Dept. Agric., May 13, 1915). Monographed by Watson. Proc. Amer. Acad. Arts & Sci. 14:278 (1879), so far as American species were then concerned.
