Distribution

Potentilla subgorodkovii is probably the most frequent entity of the group in northwestern North America: in Alaska and Yukon Territory, western Northwest Territories and Nunavut. It is the only species of the group in southern British Columbia, Alberta, and disjunct in Montana, Wyoming, and Colorado. The major part of the Alaskan and Yukon records of "P. uniflora" probably belong to P. subgorodkovii, and perhaps all records from farther south also.
