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.) |
We recognize Papaver lapponicum in a much narrower sense than did G. Knaben (1959). Much further study is needed to assess the relationships of North American populations with several taxa from the Russian Far East. Plants with rose-colored petals have been distinguished as A. lapponicum var. salmonicolor (P. alboroseum of some authors, not Hultén). Such specimens from arctic Alaska appear to be the same as P. shamurinii Petrovsky from Russia. Knowledge of P. lapponicum from Greenland, where evidently it also occurs, is inadequate to permit an accurate account of its distribution there.
