Camassia
Habit: Perennial herb; bulb 1 [or clustered (each bulb has 1 leaf-cluster, 1 scape, or both, so no need to dig up bulbs to make this determination)], coat black or brown. Leaf: basal, linear, keeled, glabrous. Inflorescence: scapose raceme; flowers 3--many; bracts 1--6 cm, narrow-lanceolate, scarious in age; pedicels 1--5 cm, spreading or incurved in fruit. Flower: +- radial (or bilateral); perianth parts 6, in 2 petal-like whorls, fused < 5% of length, 12--40 mm, lanceolate, blue to +- purple (white), 3--9 veined, twisted together above ovary in fruit [or not]; stamens 6, anthers generally 4--7 mm, attached at middle; ovary chambers 3. Fruit: loculicidal. Seed: 6--36, black. Chromosomes: n=15.
Species In Genus: +- 6 species, 4 in northwestern North America. Etymology: (chamass, qám'es, or quamash, Native American word) Note: California species highly variable, may hybridize, in need of study; bulbs traded among, eaten by Native Americans, perhaps creating local forms.
