Pedicularis densiflora
Pedicularis palustris
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 4 (1 in the flora).
Four subspecies of Pedicularis palustris have been designated in Europe; North American material appears to be subsp. palustris.
The overall form and habit of Pedicularis palustris are very similar to those of P. pennellii. Inflorescences of both species consist of paniculate racemes, and galea margins have two sets of paired teeth, one set medial and the other distal.
