Аннотация

This work presents the first schematic map of floristic zoning of Middle Povolzh’e based on analysis of the available data, distribution pattern of plants with respect to physical-geographical regions, and floristic similarity of the regions. The floristic regions are described briefly, and the species of vascular plants, which determine their specificity, are given.
