|discussion=<p><i>Chaenactis evermannii</i> is known from mountains of central Idaho. Reports of it from Washington and California/<i>Nevada</i> (P. Stockwell 1940, some as <i>C. nevadensis</i> var. mainsiana) were based on specimens of <i>C. thompsonii</i> and <i>C. alpigena</i>, respectively; all three species are closely related.</p>
