Pedicularis rainierensis
Pedicularis furbishiae
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.

Discovered in 1880, and at one time believed extinct, Pedicularis furbishiae was rediscovered in 1974 during an environmental impact survey for a proposed dam on the St. John's River and thereafter was placed on the Federal Register under the Endangered Species Act (L. W. Macior 1981). Metapopulation dynamics suggest that an ecologically intact watershed is required for long-term persistence (E. S. Menges 1990). A recovery strategy has been adopted for this species in New Brunswick (Furbish's Lousewort Recovery Team 2006; Environment Canada 2010). Pedicularis furbishiae is in the Center for Plant Conservation’s National Collection of Endangered Plants.
