Discussion | Castilleja oresbia is endemic to eastern Oregon and adjacent Idaho. It is easily confused with both varieties of C. pallescens, which also occur in sagebrush habitats. Castilleja oresbia has longer calyx lobes and softer pubescence than C. pallescens var. pallescens, although some transitional specimens are found. Castilleja oresbia has a combination of longer calyx lobes, longer pubescence, and obscurely nerved bracts, which usually serve to separate it from C. pallescens var. inverta. All three have different, though somewhat overlapping, ranges. Castilleja oresbia occasionally hybridizes with C. peckiana in Grant County, Oregon.

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.
