Ariz., Calif., Colo., Nev., Utah.
Variety subaridum is widespread and often common throughout its extensive range from southeastern California, southern Nevada, and northern Arizona to Utah and southwestern Colorado.
Variety subaridum is more closely related to </i>var.<i> nevadense than it is to </i>var.<i> ellipticum. Some populations in southwestern Utah and southwestern Colorado are distinctly shrubby, and around Zion National Park some may even have leaves glabrous on both surfaces by late fruit (e.g., Neese & Neese 9633, BRY; Thorne & Welsh 15194, BRY; Welsh et al. 27166, BRY). Such plants never have leaf blades glabrous at anthesis, as is the case with </i>var.<i> chlorothamnus. A few populations in southeastern Utah (e.g., Welsh & Thorne 25091, BRY) have densely tomentose abaxial leaf blades and approach </i>var.<i> munzii. The taxonomic significance of those differences remains to be determined.
