Discussion | Varieties 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Allium victorialis is found in North America only on Attu Island, where it is reported to be native, and on Unalaska Island, where it is reported to be introduced from Attu Island. Within this species, various subspecies and varieties have been described, but, as circumscribed, they are not clearly distinct. The North American plants have been known as subsp. platyphyllum, but until the variation within this widespread species can be worked out along natural lines, recognition of infraspecific taxa seems pointless.
