Discussion | Subspecies 2 (2 in the flora). Pedicularis racemosa occurs in the Rocky Mountains from southern Canada to New Mexico, in the Cascade Range from British Columbia to California, and in mountainous areas of Arizona. Herbarium sheets of Pedicularis racemosa are sometimes misidentified as P. contorta or P. groenlandica, but the calyx has two lobes, not five as in the latter species. The uncoiled beak also bends downward from an undomed galea, which the large lateral lobes of the abaxial lip often conceal, whereas the coiled beaks of P. contorta and P. groenlandica are very noticeable.

Pedicularis hirsuta can be difficult to distinguish from P. lanata. Unlike P. lanata, the galea subapex of P. hirsuta is toothed. Floral surfaces of P. lanata are sparsely to densely hirsute; those of P. hirsuta are glabrous. On fresh specimens, the roots of P. hirsuta are pale yellow; those of P. lanata are bright yellow.
