Habit: Daughter corms generally sessile. Leaf: 2--5, generally keeled, entire, glabrous, occasionally withered by flowering. Inflorescence: raceme- or umbel-like, generally dense; scape generally curved, twisted, or twining, cylindric; bracts +- papery; pedicels generally < flowers. Flower: perianth tube cylindric to bell-shaped, appendages at junction of tube, lobes forming crown; staminodes 0 (3, stamen-like); stamens 3, equal, or 6, unequal, 3 smaller, filaments fused to perianth tube, forming crown-like tube outside anthers, anthers attached at base; style 1, stigma weakly 3-lobed.
