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 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.
