Discussion

Pedicularis cystopteridifolia occurs only in the Rocky Mountains of Montana and Wyoming. As the specific epithet implies, the leaves strongly resemble those of the fern Cystopteris fragilis. Although not sympatric, this species could easily be misidentified as P. sudetica subsp. scopulorum, which has flowers of a similar shape and color, and leaves that are also two-pinnatifid. The secondary leaf lobes of P. cystopteridifolia, however, are much larger, longer, more deeply incised, and more heavily toothed, making them appear more finely dissected than the linear to deltate secondary and smaller toothed lobes of P. sudetica. Many of the adjacent leaf lobes of P. cystopteridifolia also overlap, whereas the lobes of P. sudetica are more widely spaced and therefore not overlapping. The galea of P. cystopteridifolia is also more highly domed and broader, and the leaves are a paler shade of green in contrast to the dark green leaves of P. sudetica subsp. scopulorum.

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).
