Discussion | Scarlet corollas with an undomed, toothless galea and two- or three-pinnatifid leaves are diagnostic of Pedicularis densiflora. This species occurs in forested subalpine regions of southern Oregon, western slopes of the Sierra Nevada, and the Coast Ranges of California south to Baja California. Herbarium records indicate northern populations of P. densiflora occur at higher elevations than do more southern populations.

Pedicularis canadensis is chiefly of the Midwestern prairies; in eastern states and provinces, it grows in forest openings and along forest edges. It also inhabits alpine wet meadows at higher elevations along the Front Range of the Rocky Mountains. Corollas may be yellow, yellow with red veins, red (forma praeclara A. H. Moore), or bicolored with a yellow corolla tube, yellow abaxial lip, and red galea (forma bicolor Farwell). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
