[Wikipedia] Habitat, Range, Toxicity: Toxicoscordion fontanum, common name small-flower death camas, is a rare plant species known only from serpentine marshes in California. It is found primarily in the Coast Ranges from Mendocino County to San Luis Obispo County, with an additional report of an isolated population in the Sierra Nevada foothills in Kern County east of Bakersfield.[3][4]
As with many other species formerly included in Zigadenus, this species is highly toxic and potentially lethal to humans and to livestock.[9] Some people have eaten it confusing it with wild onion, Allium spp. Zigadenus, despite Toxicoscordion not having the characteristic onion scent associated with Allium spp.[10][11] (link added by Mary Ann Machi)
