Discussion

Varieties 2 (2 in the flora).

Different geographic elements of Veratrum californicum have been described as separate species or varieties. The variation seems to be clinal, with most variants not consistent in their appearance or distribution. We have recognized two varieties that appear to be fairly consistent in their distributions and characteristics.

Western Native Americans (Blackfeet, Paiute, Shoshone, Thompson, and Washoe) used this species as an antirheumatic, poison, contraceptive, and emetic, as well as a skin, respiratory, blood, cold, snake bite, throat, and toothache aid (D. E. Moerman 1986).
