| 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.

Inflorescences of Pedicularis capitata display no more than five clustered flowers; the long, vertical corolla tube and curved galea that arches over the appressed, broad lobes of the abaxial lip are distinctive. The tip of the galea can be the same color as the corolla tube and abaxial lip but sometimes is a diffuse pink to purple and not distinctly bicolored as in the galeas of P. flammea or P. oederi, with which it is often confused.
