Pedicularis procera
Pedicularis capitata
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.

Inflorescences of Pedicularis capitata display no more than five clustered flowers; the long, vertical corolla tube and curved galea that arches over the appressed, broad lobes of the abaxial lip are distinctive. The tip of the galea can be the same color as the corolla tube and abaxial lip but sometimes is a diffuse pink to purple and not distinctly bicolored as in the galeas of P. flammea or P. oederi, with which it is often confused.
