Pedicularis attollens
Pedicularis chamissonis
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.

Pedicularis chamissonis differs from P. verticillata by having leaves and flowers about 1.5 times larger with a galea that is extended into a conical beak, leaves lanceolate versus elliptic, and lateral lobes of the abaxial lip more than twice the size and more pendulous.
Pedicularis chamissonis is chiefly an Asian species, found on the Kamchatka Peninsula, Kuril Islands, Sakhalin Island, and Japan; the only North American populations occur in the Aleutian Islands of Alaska.
