|discussion=<p><i>Chaenactis nevadensis</i> is known mainly from the northern Sierra <i>Nevada</i> and southern Cascade Range (Shasta to Placer counties, California; Washoe County, <i>Nevada</i>). It was recently discovered disjunct on ultramafic rocks of Bully Choop Mountain west of Redding, California, where it approaches small forms of <i>C. suffrutescens</i> in habit (see discussion there). It is sometimes cultivated in rock-gardens and may be found beyond its native range. <i>Chaenactis nevadensis</i> and <i>C. suffrutescens</i> appear to be sister or ancestor-derivative species. I have seen no evidence to support reports that <i>C. nevadensis</i> intergrades with <i>C. alpigena</i> (P. Stockwell 1940, as <i>C. nevadensis</i> var. mainsiana), with <i>C. douglasii </i>var.<i> alpina</i> (M. Graf 1999), or with any other taxon.</p>
