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.

Subspecies 4 (1 in the flora). E. Hultén (1967) listed three subspecies of Pedicularis lanata, subspp. adamsii (Hultén) Hultén, dasyantha (Hadač) Hultén, and pallasii (Vvedensky) Hultén, as occurring in Eurasia; only subsp. lanata is found in North America.
