Discussion | Subspecies numerous (4 in the flora). Many infraspecific taxa have been named from throughout the extensive range of this extremely variable species. Within North America, the following broadly circumscribed subspecies are generally, but not always, distinguishable. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
This well-marked species has its closest relatives within the Papaver alpinum complex in the mountains of central and southern Europe, e.g., P. pyrenaicum (Linnaeus) Willdenow. The report of 2n = 42, attributed by D. Löve and N. J. Freedman (1956) to A. C. Fabergé (1944), is an error; it is based on material from Pikes Peak, Colorado, where P. pygmaeum has not been found (D. F. Murray 1995).
