|discussion=<p>Variety decurrens at its most distinctive has elongate cuneate-oblanceolate, glabrate, apically toothed leaflets that are well spaced on the leaf axis. This extreme is most commonly found in the Uinta Mountains of Utah and the Medicine Bow Mountains of Wyoming. Collections from Colorado, Idaho, Montana, and <i>Nevada</i> are more equivocal and might represent hybrids or extreme forms of other (or undescribed) taxa.</p><!--
--><p>Although B. C. Johnston (1980) is provisionally followed in associating <i></i>var.<i> decurrens</i> with <i>Potentilla ovina</i>, comparisons can also be made with <i>P. drummondii</i> and <i>P. glaucophylla</i>, both placed here in sect. Graciles. Apparent intergradation exists in all directions.</p>
