Discussion
Of conservation concern.
Variety nigerrimus can be distinguished from the typical variety by its essentially glabrous foliage. This variety is endemic to southeastern Washington near the Snake River in Garfield and Whitman counties. M. E. Peck (1941) reported it (as R. hesperius) from Oregon; no collections from there have been seen as part of this review. The taxonomic status of this variant remains questionable as characters such as pubescence are not discrete and may reflect the effect of environment.
