Perennial herb from corm, outer coat fibrous [membranous]. Leaf: basal, 1–10, linear to narrow-lanceolate. Inflorescence: scapose, generally umbel-like; scape erect, generally 1(2), cylindric, generally rigid, occasionally wavy to twining; flower bracts 2–4, not enclosing flower buds. Flower: perianth parts 6 in 2 petal-like whorls, free or ± fused below into tube; staminodes 0 or 3; stamens 3 or 6, free or fused to perianth, occasionally appendaged; ovary superior, chambers 3, ovules 2–several per chamber. Fruit: capsule, loculicidal.

Key to Themidaceae
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. Fruit: generally sessile, generally ovoid, 3-angled. Seed: sharp-angled, black-crusted.Key to Dichelostemma
