Characters. - An herbaceous perennial, with a large, somewhat bulbous, very hard, transversely wrinkled, premorse root, from which arises a simple, very smooth, somewhat angular stem or scape, 1 or 2 feet in height. The cauline leaves are lanceolate, acute, small, and at some distance from each other, without petioles; the radical leaves are broader, being from 4 to 8 inches in length by half an inch to an inch in width, narrow at the base, and formed into a sort of whorl at the base of the scape. The flowers are small, very numerous, greenish-white, and are disposed in long, terminal, spicate, nodding, dioecious racemes, resembling a plume, and which are more slender and weak on the barren plants.
Male flowers with white, linear-spatulate, obtuse, one-nerved petals; 6tamens rather longer than the petals. Female flowers, the raceme is generally few-flowered, becoming erect; petals linear; stamens very short, abortive; ovary ovate, sub-triangular, with the sides deeply furrowed; stigmas 3, spreading or reflexed. Capsule ovate-oblong, tapering to the base, three-furrowed, opening at the summit. Seeds many in each cell, acute compressed.
The plant is sometimes confounded with Aletris Farinosa.
