Discussion
Of conservation concern.
Variety villosa is recognized mainly by its glabrous cypselae, lanceolate phyllaries, and geographic isolation. It is known primarily from the Big Horn Mountains in north-central Wyoming. The affinities of this poorly known taxon are obscure. It has been considered a distinct species or related to Pyrrocoma uniflora or P. integrifolia.
