Abstract

The new combination Toxicoscordion venenosum (S. Watson) Rydberg var. gramineum (Rydberg) Brasher (Melanthiaceae) is made to accommodate this taxon in this genus at the rank of variety for the Southern Rocky Mountain Interactive Flora (SRMIF) project. Recent chromosome and DNA sequence data support segregation of Toxicoscordion Rydberg from Zigadenus Michaux s.l.
