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.

Shapes of flowers and leaves of Pedicularis dudleyi are similar to those of P. semibarbata; P. dudleyi has larger vegetative features. Floral features that set P. dudleyi apart include a 10–14 mm calyx and pink to purple corolla versus a 7–9 mm calyx and pale yellow corolla in P. semibarbata.

Pedicularis dudleyi occurs in the coastal mountains of central California in Monterey, San Luis Obispo, San Mateo, and Santa Cruz counties.
