Draba heilii is restricted to Mora and Rio Arriba counties. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Although originally treated as a variety of Draba lemmonii, D. incrassata is quite distinct both morphologically (R. A. Price and R. C. Rollins 1991) and chromosomally (M. D. Windham, unpubl.). The species is known from the Sweetwater Mountains in Mono County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
