--><p>Variety murdockii grows in the central Rocky Mountains from central Idaho and southern Montana to western Wyoming and northern Colorado. It also grows in the Ruby Mountains of northern <i>Nevada</i> and the Uintah Mountains of northeastern Utah. Considerable variation occurs in quantity and quality of pubescence of the involucres of <i></i>var.<i> murdockii</i>. In some individuals the pubescence is so dense that it obscures the phyllary bodies whereas in others the individual phyllaries are clearly visible. Most commonly the pubescence consists primarily of septate trichomes, but sometimes finer non-septate trichomes predominate. Both types of trichomes may be present.</p><!--
--><p>Variety murdockii is known to hybridize with <i>Cirsium pulcherrimum </i>var.<i> pulcherrimum</i> and <i>C. scariosum </i>var.<i> scariosum</i> in Wyoming.</p>
