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 ornithorhynchos is commonly misspelled in the literature as P. ornithorhyncha. As this is the orthography used in floras since C. L. Hitchcock et al. (1955–1969, vol. 4), it also appears on recent herbarium specimens. How this error arose is unclear because the same misspelling also appears on specimens older than 1959. Another occasional misspelling is ornithorhynchus.

The galeas of Pedicularis ornithorhynchos taper into long conical, uncoiled beaks that are very conspicuous above the horizontally expanded lateral lobes of the abaxial lips. No more than 15 flowers are borne on the capitate heads, with the internodes greatly expanding as the fruits develop. Compared to the basal leaves, the cauline leaves of the inflorescence are very few and much shorter, but otherwise similar in form. This alpine and tundra species occurs in the Alaskan panhandle and Coast Mountains as well as the coast ranges of mainland British Columbia south into the northern Cascade Range as far south as Mount Rainier; it is also recorded from alpine areas on Vancouver Island and the Haida Gwaii (Queen Charlotte Islands), British Columbia.

Pedicularis ornithorhynchos is pollinated by bumblebees that hang inverted from the galea and cause release of pollen by wing-muscle vibrations (L. W. Macior 1973).
