Discussion

Castilleja attenuata is a common and widespread species, ranging from southwestern Canada to northern Baja California, with several disjunct populations in central Chile. It is sensitive to competition from weeds. Disjunct populations in the Rincon Mountains in Pima County, Arizona, often have pink bracts but are otherwise typical.

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.
