Draba petrophila is often broadly circumscribed to include the taxon herein called D. viridis. For a discussion of the differences between these species and the closely related D. helleriana, see I. A. Al-Shehbaz and M. D. Windham (2007). Draba petrophila, in the strict sense, is known only from Cochise, Pima, and Santa Cruz counties in southeastern Arizona.

Draba pterosperma is a distinctive species that is restricted to the Marble Mountains of northern California (Siskiyou County). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
