About Death Camas (Toxicoscordion venenosum) Toxicoscordion venenosum, with the common names death camas and meadow death camas, is a species of flowering plants in the genus Toxicoscordion, of the Melanthiaceae family. It is native to western North America. The plant is called alap ?a? in Sahaptin, and nupqasaqu? ("nup-ka-sa-qush") in Ktunaxa). The plant is widespread across much of Western Canada, the Western United States, and northern Baja California (M xico). They tend to grow in dry meadows and on dry hillsides as well as sagebrush slopes and montane forests. Toxicity. All parts of the plant are poisonous. It is dangerous for humans as well as livestock.
