 raceme, the lower ones first expanding. Perianth of 6 distinct glandless persistent obtuse 

 segments. Stamens inserted on the bases of the sepals; anthers small, reniform. Ovary

8. STENANTHIUM Kunth, Enttm. 4: 189. 1842. 



Erect glabrous bulbous herbs, with leafy stems and small white or greenish, polygamous 

 flowers in an ample terminal penicle. 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 ovoid-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.]
