Deathcamas or death camas refers to several species of flowering plant in the tribe Melanthieae. The name alludes to the great similarity of appearance between these toxic plants, which were formerly classified together in the genus Zigadenus, and the edible camases (Camassia), with which they also often share habitat. Other common names for these plants include deadly zigadene, hog potato and mystery-grass.
