|discussion=<p>Plants of <i></i>subsp.<i> arenosa</i> from Alaska and Yukon tend to be larger, with more open inflorescences and more distinctly petiolulate central leaflets, than plants in north-central Canada. Some collections from the range of <i>Potentilla furcata</i> (sect. Rubricaules) have red glands in the inflorescence, suggesting introgression between <i>P. arenosa</i> and <i>P. furcata</i>. Reported occurrences in Alberta and Saskatchewan (and the upper altitudinal limit given here) might actually be <i>P. hookeriana</i> as now circumscribed.</p>
