Discussion

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.
