Not to Be Confused With:
No close lookalikes in the study area; without flower could possibly be confused with Zygadenus elegans (Death Camas), but can be distinguished by onion-like smell.
Sulfenic acid gives onions their distinctive odour. Cutting or bruising the cells of Allium spp. releases this volatile acid into the air, causing burning of the eyes.
