Rocky Mountain draba, thick-leaved draba, snowbed whitlow-grass
Publication: Edinburgh New Philos. J. 7: 182. 1829.
Origin: Native
Herbarium search: CPNWH
Notes: FNA7: "M. D. Windham (2004) presented morphological and chromosomal data suggesting that Draba crassifolia is an allopolyploid produced by hybridization between D. albertina and D. fladnizensis. Although the species is distinctive in large part, some individuals can be difficult to place and there is evidence of rare backcrossing (Windham, unpubl.)."
