Draba helleriana is highly variable and was divided by C. L. Hitchcock (1941) into four varieties. For a discussion of those and the circumscription of the species, see I. A. Al-Shehbaz and M. D. Windham (2007). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Although originally treated as a variety of Draba cuneifolia, D. californica is but distantly related to that species. Instead, ongoing studies (L. Allphin and M. D. Windham, unpubl.) suggest that it may be an allopolyploid resulting from hybridization between D. albertina and D. breweri. The species is restricted to the White Mountains in Mono County, California, and adjacent Esmeralda County, Nevada. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
