Pedicularis bracteosa
Pedicularis semibarbata
Varieties 8 (8 in the flora).
Pedicularis bracteosa is found in subalpine habitats across much of western North America, occurring throughout the Rocky Mountains from central British Columbia and Alberta to northern New Mexico, as well as the Coast Range south to northern California.

Subspecies 2 (2 in the flora).
The basal and cauline leaves of Pedicularis semibarbata are distinctly one- or two-pinnatifid into deep pinnae and narrow subpinnae with serrate margins. The leaves and bracts far exceed the length of the inflorescence, often concealing it. Obvious spatulate, tan-colored, undivided, and membranous leaves are proximal to the divided basal leaves, but they are not as conspicuous as those of P. centranthera, a species with a similar growth form. Proximal floral bracts of P. semibarbata are similar to basal and cauline leaves, whereas in some specimens the distal bracts are spatulate and either once-divided or merely serrate at the apex. Surfaces of the corolla tube and sometimes the galea as well are hispid.
Pedicularis semibarbata grows under ponderosa pine, incense cedar, sugar pine, and white fir, primarily in the southern Cascade Range and Sierra Nevada, in the San Bernardino and San Gabriel mountains of California, and the Mount Charleston region of Nevada.
The flowers of Pedicularis semibarbata in Yosemite National Park were pollinated only by Osmia tristella (L. W. Macior 1977).
