Castilleja thompsonii
Castilleja raupii
Castilleja thompsonii is a characteristic species of the sagebrush communities on the eastern slope of the Cascade Range in Washington, and in the high deserts of the Columbia Basin. Historically, its range approached but apparently never entered Idaho in the Spokane River valley, but much of its habitat in that area is now converted to agriculture or suburban development or overwhelmed by non-native, invasive plants. Castilleja thompsonii occurs in a few sites in the Okanogan Valley region of southern British Columbia and at one site on the eastern slopes of the Cascade Range in Wasco County, Oregon. A distinctive form from the subalpine and alpine zones of Mt. Adams, in the southern Cascade Range of Washington, was named C. villicaulis. This form may merit varietal status under C. thompsonii. While both names were described in the same paper, C. thompsonii is the name used in all regional floras since their publication, after C. villicaulis was reduced to synonymy by M. Ownbey (1959).

Castilleja raupii is a member of the difficult C. pallida species complex. Castilleja raupii is widespread from southern Alaska to northern Alberta, northwards to the shore of the Arctic Sea, and east to the eastern shore of Hudson Bay. Reports from northeastern Russia are mostly referable to the similar Asian species, C. rubra (Drobow) Rebristaya. Castilleja raupii is sometimes confused with the partially sympatric C. elegans, but C. raupii is a taller plant with often somewhat branched, ascending-erect stems and is often found on more mesic substrates than C. elegans. The inflorescences of C. raupii are usually pink to pink-purple, but more variably colored populations are reported from the delta region of the Mackenzie River in the Northwest Territories of Canada.
