Discussion

Varieties 2 (2 in the flora).

Veratrum viride consists of two clearly related, disjunct populations, one in eastern and one in western North America. These were clearly separated by continental glaciation and have subsequently evolved in isolation. Nonetheless they show many critical features in common, and individual plants from either region occasionally show one or more features common to plants in the other. The two populations have been variously classified as separate species, varieties, or subspecies, or as a single taxon. We have chosen to recognize two distinctive, if subtle, varieties.

(If the plant you're looking for doesn't show up in the auto-complete list, that means it either isn't described in Flora of North America yet, or it's listed under a synonym. And please note that Flora of North America is still missing several plant families, including Fabaceae, Apiaceae, Boraginaceae, and Polemoniaceae.)
