Pedicularis oederi
Pedicularis dudleyi
Pedicularis oederi is known from the mountains of Europe, Asia, and western North America.
Two arctic species can be easily confused with Pedicularis oederi. Pedicularis flammea also has bicolored flowers that are yellow with galeas that are red- or purple-tipped, but the flowers of P. oederi are twice the size of those of P. flammea. The flowers of P. capitata are sometimes also yellow but may or may not be bicolored. If bicolored, the color is more diffuse and lighter than that of either P. flammea or P. oederi. The flowers of P. capitata are also larger than those of P. oederi. In addition, the inflorescences of P. capitata usually have no more than five flowers clustered at the tips, while those of P. oederi have at least 10 to 50 flowers along at least one third their lengths. H. J. Scoggan (1978–1979) listed P. oederi var. albertae based upon its densely woolly inflorescence.

Shapes of flowers and leaves of Pedicularis dudleyi are similar to those of P. semibarbata; P. dudleyi has larger vegetative features. Floral features that set P. dudleyi apart include a 10–14 mm calyx and pink to purple corolla versus a 7–9 mm calyx and pale yellow corolla in P. semibarbata.
Pedicularis dudleyi occurs in the coastal mountains of central California in Monterey, San Luis Obispo, San Mateo, and Santa Cruz counties.
