Pedicularis rainierensis
Pedicularis canadensis
Pedicularis rainierensis is known from Mt. Rainier and the Crystal Mountain area. The species is easily confused with P. bracteosa var. latifolia, which often occurs in the same meadows. While the sizes and shapes of their flowers are nearly indistinguishable, P. rainierensis is a much smaller plant with leaves only about three fourths the size, proximal leaf lobes less than one fifth the size, inflorescences about one half the length, and the number of flowers greatly reduced in comparison to those of P. bracteosa var. latifolia.

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).
