Discussion | 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.

The long corolla tubes of Pedicularis lanceolata are uncharacteristically nectarless, and only late season pollen-foraging worker bumblebees pollinate this species (L. W. Macior 1969). The uniquely hinged abaxial lip covering the opening of the galea is an adaptation to allow only worker bumblebees access to the anthers, as they must learn to push it aside during foraging.
