Dale W. McNeal, except as specified

Perennial to trees, from membranous bulb, fibrous corm, scaly rhizome, or erect caudex
Stem generally underground
Leaves generally basal, often withering early, alternate, generally ± linear
Inflorescence various, generally bracted
Flower generally bisexual, generally radial; perianth often showy, segments generally 6 in two petal-like whorls (outer sometimes sepal-like), free or fused at base; stamens 6 (or 3 + generally 3 ± petal-like staminodes), filaments sometimes attached to perianth or fused into a tube or crown; ovary superior or inferior, chambers 3, placentas generally axile, style generally 1, stigmas generally 3

Genera in family: ± 300 genera, 4600 species: especially ± dry temp and subtropical; many cultivated for ornamental or food; some TOXIC. Here includes genera sometimes treated in Agavaceae, Amaryllidaceae, and other families.

CALOCHORTUS

Peggy Fiedler and Bryan Ness

Bulb coat generally membranous
Leaves generally linear to lanceolate; basal leaf 1; cauline leaves 0–several, smaller upwards
Inflorescence often ± umbel-like; flowers 2–many
Flower spheric and closed to nearly rotate; sepals generally < petals, generally ± lanceolate (ovate), generally nearly glabrous; petals generally widely wedge-shaped, generally hairy inside, nectary near base; filaments ± flat, anthers generally attached at base; style 1, stigmas 3
