Discussion | Castilleja disticha is limited to the central and southern Sierra Nevada. Although similar to C. applegatei and C. martini, C. disticha is distinctive and unique in its long, colorful, and highly exserted corollas with the beak exceeding the tube in length, calyces more brightly colored than the often unlobed bracts, and tall, strongly distichous growth form.

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.
