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.

Pedicularis flammea is often confused with P. oederi, which also has red- or purple-tipped galeas. Compared to other Pedicularis species, including P. oederi, flowers of P. flammea are much smaller.

Pedicularis flammea is a boreal-arctic species found only in northern parts of many Canadian provinces.
