Discussion

In its native range, Papaver argemone is a complex of five diploid, tetraploid, and hexaploid subspecies (J. W. Kadereit 1986, 1990). Apparently two or more of these have been represented among the crop weeds and ballast waifs introduced in North America, where plants are difficult to assign to particular subspecies. The species should be expected elsewhere in the flora. Collections attributed to Maryland, Ohio, and Virginia are known also, but they lack more specific citations of locality.
