Discussion | Although Pedicularis grayi A. Nelson appears in older floras, the name is superfluous and illegitimate. Pedicularis procera Adams ex Steven 1822 is invalid. Pedicularis procera is the tallest species of Pedicularis in North America. Because the leaves closely resemble those of P. bracteosa, smaller plants can be easily mistaken for this species.

Pedicularis pulchella occurs in the Absaroka and Beartooth ranges of southwestern Montana and northwestern Wyoming, the Anaconda and Madison ranges of Montana, and one site in the Cascade Range of Washington. The overlapping adjacent lobes of its two-, or sometimes three-, pinnatifid leaves are a characteristic feature of P. pulchella.
