Discussion | Castilleja chlorotica is an uncommon to rare endemic on dry slopes in Deschutes, Klamath, Lake, and possibly Crook counties in central Oregon. The hooked corolla beak and greenish bracts, often aging purplish distally, help distinguish it from similar species such as C. glandulifera and yellow forms of C. applegatei var. pinetorum.

Castilleja elegans is a characteristic species of the arctic and arctic-alpine regions. Its eastern and western limits are poorly understood, due to confusion with the similar species C. raupii to the east and south, and with C. rubra (Drobow) Rebristaya in eastern Asia. All three are part of a morphologically variable complex of recently evolved and poorly differentiated entities informally known as the C. pallida complex, after the first-described member of the group. Some reports of C. elegans in eastern Canada are here referred to C. septentrionalis. A recent collection of C. elegans from the northern Canadian Rocky Mountains is apparently disjunct, though it may also suggest its wider presence in Alberta.
