|discussion=<p>The entire to tridentate leaflets of <i>Potentilla bicrenata</i> generally serve to distinguish this species from <i>P. concinna</i>. Unequivocal <i>P. bicrenata</i> is most common in Utah and the southern Rocky Mountains from New Mexico to central Colorado; in Arizona, it is documented only from the Kaibab Plateau. Wyoming populations tend to be transitional to <i>P. concinna </i>var.<i> concinna</i> in leaflet toothing and/or petal size. Some collections from as far north as Waterton Lakes National Park, Alberta, vary in the direction of <i>P. bicrenata</i> but are retained here in <i>P. concinna</i>.</p>
