Pedicularis densiflora
Pedicularis centranthera
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.

The leaves of Pedicularis centranthera exceed the inflorescence, giving the impression that the cauline leaves are basal. Proximalmost basal leaves are distinct: brown, membranous, and spatulate with undivided and entire margins. Pedicularis semibarbata has similar basal leaves.
Pedicularis centranthera occurs in evergreen forests, often under pinyon pine, juniper, ponderosa pine, and yellow pine.
