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.

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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
