Zigadenus venenosus, commonly called death camas or meadow deathcamas, is a flowering plant in the genus Zigadenus belonging to the Melanthiaceae. It grows up to 70 cm tall with long, basal, grass-like leaves.[1][2] The bulbs are oval and look like onions but do not smell like onions.[3] The flowers are cream coloured or white and grow in pointed clusters[3], flowering between April and July.[4] Death camas occurs in some parts of western North America[1] and can be easily confused with edible onions of genus Allium[3]. They tend to grow in dry meadows and on dry hillsides as well as sagebrush slopes and montane forests. [3][4] Called alapíšaš in Sahaptin.

All parts of the plant are poisonous. It is dangerous for humans as well as livestock, though some poisoned by it have been treated.[4] Alkaloids are responsible for the plants being poisonous and it's said eating rich fish or beef broth, grease, or butter may counteract the poison.[3] The Meadow Deathcamas Toxicoscordion venenosum (called ałtsíniitsoh, literally "big mariposa lily") was used by the Navajo for treatment of coyote bites.
