|discussion=<p>In North America, <i>Potentilla biflora</i> is mostly Beringian, barely reaching northern British Columbia and western Northwest Territories, with one locality in Nunavut (southern Victoria Island). The amphi-Beringian range is strongly isolated from other Asian populations, the closest being in the Altai Mountains of south-central Siberia. Two varieties are accepted in China (Li C. L. et al. 2003c), with North American plants falling in <i></i>var.<i> biflora</i>.</p>
