|discussion=<p>Varieties 2 (2 in the flora).</p><!--
--><p><i>Potentilla glaucophylla</i> replaces P. diversifolia; an examination of the lectotype of the latter confirms J. Soják’s (1996) conclusion that P. diversifolia applies to a hybrid involving <i>P. glaucophylla</i> and <i>P. hippiana</i>. Historically, this species was often termed <i>P. dissecta</i> Pursh, a misapplied name that has been rejected (B. Ertter et al. 2008).</p><!--
--><p>In addition to the nomenclatural change, the circumscription of <i>Potentilla glaucophylla</i> is here restricted to plants with usually glaucous, blue-green, distally toothed leaflets that are usually glabrate (at least in <i></i>var.<i> glaucophylla</i>). Plants from the Colorado Plateau and southern Rocky Mountains formerly included in this species and having dark green leaves, more leaflet teeth, and larger anthers are transferred either to <i>P. townsendii</i> or to a currently undescribed entity.</p><!--
--><p>The two-ranked leaves of <i>Potentilla glaucophylla</i> suggest a possible connection to <i>P. crantzii</i> in sect. Aureae.</p>
