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.

The flowers of Pedicularis labradorica are usually yellow or dark yellow, and the galea is tinged distally with red or purple; sometimes, the yellow color of the tube abruptly transitions into red or purple. Hultén based var. sulphurea on the solid yellow color variant from the Yukon. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
