Discussion | Scarlet corollas with an undomed, toothless galea and two- or three-pinnatifid leaves are diagnostic of Pedicularis densiflora. This species occurs in forested subalpine regions of southern Oregon, western slopes of the Sierra Nevada, and the Coast Ranges of California south to Baja California. Herbarium records indicate northern populations of P. densiflora occur at higher elevations than do more southern populations.

Subspecies 2 (2 in the flora). Pedicularis langsdorffii may be mistaken for P. hirsuta, P. lanata, and P. sudetica, which have similar growth forms and habitat requirements. Pedicularis langsdorffii generally has larger, pink to lavender corollas with toothed galeas that strongly arch over the abaxial lips in contrast to the smaller, toothless, pink corollas and slightly arching galeas of P. lanata. Pedicularis sudetica has up to five cauline leaves or lacks them. The straight, smaller galeas and pale pink or white corollas of P. hirsuta differentiate it from P. langsdorffii.
