| Discussion | 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.

Subspecies 2 (2 in the flora). Pedicularis racemosa occurs in the Rocky Mountains from southern Canada to New Mexico, in the Cascade Range from British Columbia to California, and in mountainous areas of Arizona. Herbarium sheets of Pedicularis racemosa are sometimes misidentified as P. contorta or P. groenlandica, but the calyx has two lobes, not five as in the latter species. The uncoiled beak also bends downward from an undomed galea, which the large lateral lobes of the abaxial lip often conceal, whereas the coiled beaks of P. contorta and P. groenlandica are very noticeable.
