| 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.

Pedicularis sylvatica is considered by L. Brouillet et al. (http://data.canadensys.net/vascan/) to be introduced in the flora area. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
