Pedicularis procera
Pedicularis semibarbata
Although Pedicularis grayi A. Nelson appears in older floras, the name is superfluous and illegitimate. Pedicularis procera Adams ex Steven 1822 is invalid.
Pedicularis procera is the tallest species of Pedicularis in North America. Because the leaves closely resemble those of P. bracteosa, smaller plants can be easily mistaken for this species.

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).
