|discussion=<p><i>Potentilla bimundorum</i> is the correct name for what has been treated as <i>P. multifida</i> Linnaeus in North America. It is the only American representative of the mainly Eurasian <i>P. multifida</i> group, which is sometimes treated as a distinct section. J. Soják (2005) presented a useful survey and key to this group, showing that its species, in spite of being merged within <i>P. multifida</i> in the broad sense by many authors, are each distinct and with their own range. <i>Potentilla</i> multifida in the narrow sense is restricted to eastern Europe and western Siberia.</p>
