|discussion=<p><i>Perityle</i> stansburii with its large habit, relatively broad leaves, radiate heads, bristle pappus, chromosome number, and wide distribution, fills most expectations as the ancestral taxon of the group of related species called the “southwestern alliance.” This natural assemblage of taxa, which is thought to have evolved through geographic displacement and subsequent genetic differentiation, includes <i>P. congesta</i>, <i>P. gracilis</i>, <i>P. intricata</i>, <i>P. inyoensis</i>, <i>P. megalocephala</i>, <i>P. specuicola</i>, <i>P. tenella</i>, and <i>P. villosa</i>. These taxa, which are found mostly to the south and west of P. stansburii, all have rayless heads and may or may not have pappus bristles. In western and northwestern Utah and adjacent <i>Nevada</i>, P. stansburii occurs in crevices of rock exposures.</p>
