|discussion=<p>Variety peckii occurs from Steens Mountain and the Pueblo Mountains of Harney County, Oregon, south to the Black Rock Range and Jackson Mountains of Humboldt County, <i>Nevada</i>. On the lower portion of its distribution along Steens Mountain Loop Road at an elevation of about 1900 m, <i></i>var.<i> peckii</i> and <i>Cirsium inamoenum</i> grow together and freely hybridize, forming a complex hybrid swarm. Intermediates variably combine the features of the parent taxa, with the habit more openly branched than typical for <i>C. eatonii </i>var.<i> peckii</i>, variably arachnoid tomentose leaves, ± glandular phyllaries, and lavender to pale pink flowers. Variety peckii may range as far south as the West Humboldt Mountains. The type of <i>Cirsium</i> humboldtense Rydberg (<i>Carduus</i> nevadensis Greene) closely resembles some of the hybrids between <i>C. inamoenum</i> and <i>C. eatonii </i>var.<i> peckii</i>.</p>
