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.

Pedicularis cystopteridifolia occurs only in the Rocky Mountains of Montana and Wyoming. As the specific epithet implies, the leaves strongly resemble those of the fern Cystopteris fragilis. Although not sympatric, this species could easily be misidentified as P. sudetica subsp. scopulorum, which has flowers of a similar shape and color, and leaves that are also two-pinnatifid. The secondary leaf lobes of P. cystopteridifolia, however, are much larger, longer, more deeply incised, and more heavily toothed, making them appear more finely dissected than the linear to deltate secondary and smaller toothed lobes of P. sudetica. Many of the adjacent leaf lobes of P. cystopteridifolia also overlap, whereas the lobes of P. sudetica are more widely spaced and therefore not overlapping. The galea of P. cystopteridifolia is also more highly domed and broader, and the leaves are a paler shade of green in contrast to the dark green leaves of P. sudetica subsp. scopulorum.
