Pedicularis procera
Pedicularis attollens
Although Pedicularis grayi A. Nelson appears in older floras, the name is superfluous and illegitimate. Pedicularis procera Adams ex Steven 1822 is invalid.
Pedicularis procera is the tallest species of Pedicularis in North America. Because the leaves closely resemble those of P. bracteosa, smaller plants can be easily mistaken for this species.

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.
