The variability structure of 18 morphological floral characters of Potentilla bifurca in 28 coenopopulations of
Altai-Sayan Mountain region has been studied. Classification of the characters studied into groups on the basis of relative variability and determinacy has been performed. Distinctions between flower indices individuals of coenopopulations (40.0–92.5 %), coenopopulations in a province (9.5–50.6 %) and coenopopulations in different provinces (2.9–27.1 %) contribute significantly to total variation. Evidence of sexual dimorphism in P. bifurca flowers is independent of conditions of growth.
