Pedicularis oederi
Pedicularis attollens
Pedicularis oederi is known from the mountains of Europe, Asia, and western North America.
Two arctic species can be easily confused with Pedicularis oederi. Pedicularis flammea also has bicolored flowers that are yellow with galeas that are red- or purple-tipped, but the flowers of P. oederi are twice the size of those of P. flammea. The flowers of P. capitata are sometimes also yellow but may or may not be bicolored. If bicolored, the color is more diffuse and lighter than that of either P. flammea or P. oederi. The flowers of P. capitata are also larger than those of P. oederi. In addition, the inflorescences of P. capitata usually have no more than five flowers clustered at the tips, while those of P. oederi have at least 10 to 50 flowers along at least one third their lengths. H. J. Scoggan (1978–1979) listed P. oederi var. albertae based upon its densely woolly inflorescence.

Subspecies 2 (2 in the flora).
The flowers of Pedicularis attollens, like those of P. groenlandica, resemble an elephant’s head, and A. Heller placed them both in Elephantella. The short, upturned beak, in contrast to the long, more horizontal downturned beak of P. groenlandica, is a distinguishing feature of P. attollens. Whereas P. groenlandica occurs across much of western and arctic North America, P. attollens is found primarily in the Cascade Range of central and southern Oregon and the Sierra Nevada of California and Nevada. It is also reported from the Klamath Range to the west and the White and Sweetwater mountains and the Warner Range to the east of the Sierra Nevada.
