|discussion=<p><i>Castilleja occidentalis</i> has a wide distribution in the southern Rocky Mountains, a gap in its distribution in Wyoming, and reappears in Montana and the Canadian Rockies. Bract lobing and color vary considerably but without correlation to geography. Although <i>C. occidentalis</i> resembles an alpine form of <i>C. septentrionalis</i>, <i>C. occidentalis</i> is missing in several regions in the distribution of the latter, even when extensive areas of suitable habitat are available, and has a discrete range.</p>
