Castilleja elegans
Castilleja hyperborea
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.

Castilleja hyperborea is widespread across boreal, alpine, and arctic habitats in western Canada and Alaska, extending into the Russian Far East. A rare form with light purple bracts was named as C. kuschei. Another form with particularly long hairs found in the Kluane Lake region of the southern Yukon was described as C. villosissima and is usually found on calcareous substrates.
