J. Chris Pires & Glenn Keator


Corm spheric, tan; daughter corms sessile. Leaf: 1–3, generally narrow-lanceolate, keeled, glabrous, entire, often withered at flower. Inflorescence: umbel-like, open; bracts ± lanceolate, ± scarious; pedicels ± erect, generally > perianth; flowers generally many. Flower: perianth tube generally funnel-shaped, lobes generally ascending to spreading; stamens 6, attached to perianth tube at 1 level or alternately at 2 levels, equal or short alternating with long, filaments free, appendages forming crown or generally 0, anthers attached at middle, generally angled away from stigma; ovary stalked, style 1, stigma ± 3-lobed. Fruit: generally stalked, ovoid. Seed: ± spheric, black-crusted.
15 species: western North America, especially northern and central California. (Greek: 3 complete, for flower parts in 3s)
