We STENANTHIUM Kunth, Enum. 4: 189. 1842. 
Erect glabrous bulbous herbs, with leafy stems and small white or greenish, polygamous 
flowers in an ample terminal panicle. Leaves narrowly linear, keeled. Perianth-segments 
narrowly lanceolate, acuminate, glandless, spreading, persistent, adnate to the base of the 
ovary. Stamens shorter than the perianth-segments, inserted on their bases; anthers small, 
cordate or reniform. Ovary ovoid. Capsule ovyoid-oblong, 3-lobed, finally dehiscent to the 
base, the lobes with short slightly divergent beaks. Seeds about 4 in each cavity, oblong, 
angled, somewhat flattened. [Greek, in allusion to the narrow perianth-segments. ] 
The genus comprises only the two following species: 
Leaves 2''-3'' wide; capsule reflexed. 1. S. gvamineum.
