Pedicularis densiflora
Pedicularis labradorica
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 flowers of Pedicularis labradorica are usually yellow or dark yellow, and the galea is tinged distally with red or purple; sometimes, the yellow color of the tube abruptly transitions into red or purple. Hultén based var. sulphurea on the solid yellow color variant from the Yukon.
