Pedicularis canadensis
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).
