coast mountain draba, coast mountain whitlow-grass
Publication: Proc. Biol. Soc. Wash. 43: 117. 1930.
Origin: Native
Herbarium search: CPNWH
Notes: FNA7: "C. L. Hitchcock (1941) treated Draba ruaxes as a variety of D. ventosa; as demonstrated by G. A. Mulligan (1971b), the two are quite distinct. Draba ruaxes is an outcrossing hexaploid with well-formed anthers and pollen, and abundant, simple trichomes on leaves, stems, sepals, and fruits. By contrast, D. ventosa is an apomictic triploid with abortive anthers and/or pollen, and no simple trichomes anywhere on the plant."
