|discussion=<p>The northern arctic plants have glabrous leaves and are compatible with Potentilla egedei. Some of the southern arctic and northern boreal plants in the Atlantic regions have leaves with white-hairy abaxial surfaces, more leaflets, often more pointed teeth, and slightly larger flowers. These are compatible with subsp. groenlandica as originally described. The variation between these extremes is continuous. Both names are based on plants from Greenland, far north of the native range of subsp. anserina, and are probably the same entity. Following the argument by J. Soják (1969) that trinomials by Trattinnick are subspecies, the epithet groenlandica has priority over egedei at this rank.</p>
