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.) |
In view of intermediate forms in the Alaska Range, we have broadened the concept of Papaver mcconnellii to include P. denalii. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
