Abstract
A new locality of the taxon from the genus Potentilla, endemic to the flora of Russia and Kazakhstan, was discovered in Eastern Europe. Previously, P. × angarensis was recorded for the European part of Russia based on collections from Moscow Region and the Republic of Udmurtia. The paper reports the first record of this hybrid for the Oka-Don Lowland, which was found in the northeast of the Voronezh Region. The main morphological characters of the hybridogenic taxon, which distinguish it from closely related species, are listed. The general distribution of P. × angarensis is specified. An image of the herbarium specimen of the new record is presented.
