|discussion=<p>Variety subaridum is widespread and often common throughout its extensive range from southeastern California, southern <i>Nevada</i>, and northern Arizona to Utah and southwestern Colorado.</p><!--
--><p>Variety subaridum is more closely related to <i></i>var.<i> nevadense</i> than it is to <i></i>var.<i> ellipticum</i>. 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></i>var.<i> chlorothamnus</i>. A few populations in southeastern Utah (e.g., Welsh & Thorne 25091, BRY) have densely tomentose abaxial leaf blades and approach <i></i>var.<i> munzii</i>. The taxonomic significance of those differences remains to be determined.</p>
