--><p><i>Potentilla holmgrenii</i> is known only from the Schell Creek and Snake ranges, <i>Nevada</i>, and Deep Creek Range, Utah. In addition to characteristics given in the key, lateral leaflets and leaflet teeth of <i>P. holmgrenii</i> are directed more forward than in <i>P. nivea</i>, leaflets are thicker and more densely hairy, and the terminal tooth is often orbiculate and frequently overlapped by the adjacent pair of lateral teeth.</p>
