a genus of scapose herbs of North and South America having large edible bulbs.

Camassia is a genus of six species, native to western North America, from southern British Columbia to northern California, and east to Utah, Wyoming and Montana. Historically, the genus was thought to belong to the lily family (Liliaceae), the Scilloideae family, or the Hyacinthinaceae family, but from DNA and biochemical studies, the APG II-group has reassigned Camassia to the family Agavaceae. Common names include Camas, Quamash, Indian hyacinth, and Wild hyacinth.
