--><p>Although sect. Biflorae deviates from the main body of <i>Potentilla</i> and superficially resembles the mainly Asian genus <i>Dasiphora</i> in shoot and leaf architecture and in some floral features, molecular analyses place the species unequivocally in the <i>Potentilla</i> clade, not in the <i>Fragaria</i> clade with <i>Dasiphora</i> (C. Dobeš and J. Paule 2010; M. H. Töpel et al. 2011).</p>
