|discussion=<p><i>Lithophragma tenellum</i> usually occurs on the eastern side of the Cascade Mountains and in the Rocky Mountains, <i>Nevada</i>, and Utah into western North America.</p><!--
--><p>Taxonomy of <i>Lithophragma tenellum</i> is poorly understood because there are few collections from widely divergent geographical areas. The northwestern population (Washington, British Columbia) has been separated as a distinct species (L. thompsonii) based on the extent of the basal leaf lobation, which often shows considerable variation in all species. However, other populations in the Rocky Mountains, <i>Nevada</i>, and Utah have been observed with this lobation, as has Washington-British Columbia material having the more typical leaf form.</p>
