On the basis of investigation of the features of pollen of 16 coenopopulations of Potentilla bifurca in five provinces of the Altay-Sayan mountain region, two groups of coenopopulations were revealed: western and eastern. Both groups are characterized by the high intrapopulation (44,7-63,9 %) and lower interpopulation (11,4-42,2 %) variability. The observed similarity between the groups of coenopopulations of P. bifurca from different geobotanical provinces is determined by their common origin in the steppe communities of Pliocene-Pleistocene.
