Pedicularis lanata
Pedicularis hirsuta
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.

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.
