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 often present. Leaf: generally 1–6, linear, generally crescent-shaped in ×-section, glabrous, entire, often withered at flower. Inflorescence: open; scape 2–70 cm, generally slender, generally straight, cylindric; bracts scarious; pedicels generally > flowers, generally < 13 cm. Flower: perianth tube bell- to funnel-shaped, green-white, lobes erect to spreading, violet to lavender, occasionally pink, midribs purple or green; staminodes (0)3, generally ± erect, opposite outer lobes, white to violet or lavender, lateral margins flat, incurved, or inrolled; stamens 3, equal, fused to perianth, opposite inner lobes, filaments occasionally winged or appendaged, free or fused basally to staminodes, generally not forming crown-like tube, anthers attached at base, appressed to style, abaxially papillate; style 1, stigma lobes 3, spreading and recurved. Fruit: sessile, ovoid. Seed: oblong, black, lined, angles ridged.Key to Brodiaea
