Discussion | 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.

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.) |
