• Popis: In August 2005, Potentilla turkestanica was collected in the south-eastern Altai Mts. in an alpine meadow in the Taldura River valley above the north-western margin of the Chuya steppe. Until recently, the species has been known only from north-western China and Mongolia; this is the first record from Russia. Potentilla turkestanica is a hybridogenous species of P. sect. Niveae. It is similar to P. evestita, but differs from it by 5-foliolate leaves. The morphological differences from two similar species, P. alluvialis and P. anjuica, are briefly described in the paper.
