Discussion

Variety adenophora is largely restricted to western Colorado, northeastern Arizona, and northwestern New Mexico. The apparent allopatric distributions of the two varieties provide support for the recognition of var. adenophora. This is further justified in that the glandular variety abuts the range of the Rocky Mountain Eremogone fendleri. It is assumed that the presence of glandular stems in each of these taxa is of independent origin.

Plants of var. adenophora may be more likely than those of var. eastwoodiae to exhibit pink petals, and they often look smaller, with fewer flowers in a less-open inflorescence. Occasional specimens that we have examined suggest that this taxon may be polyphyletic.
