Glabrous throughout, rootstock a short crown 

 with numerous fibrous roots. Scape 2-6 tall, 

 rather slender, sometimes nearly i' in diameter at 

 the base, ^its bracts distant, long-acuminate, the 

 lower 3'-6' long; leaves narrowly oblong, i-2 

 long, i'-2i' wide, acuminate, their margins entire 

 or denticulate; spike i-2 long, loose; flowers 

 greenish yellow, odorous, solitary in the axils of 

 short bracts, sessile or the lowest distinctly pedi- 

 celled; perianth nearly tubular, slightly expanded 

 above, o'-ia" long, the tube about twice as long as 

 the erect lobes; filaments at length about as long as 

 the perianth; Capsule 5 "-8" in diameter, slightly 

 longer than thick, abruptly contracted into a short 

 stalk.

Low, mostly villous herbs with a corm or short rootstock, grass-like leaves and slender 

 few-flowered scapes, the flowers rather small. Perianth 6-parted, its segments equal or 

 nearly so, separate to the summit of the ovary, spreading, withering-persistent, the 3 outer 

 ones greenish on the lower side in our species. Stamens inserted on the bases of the peri- 

 anth-segments ; filaments short ; anthers erect, sagittate or entire. Ovary 3-celled ; style 

 short ; stigmas 3, erect ; ovules numerous, in 2 rows in each cavity. Capsule subglobose or 

 oblong, thin-walled, not dehiscent by valves. Seeds globular, black, laterally short-beaked 

 by their stalks. [Greek, originally given to some plant with sour leaves.]
