Flora Diversity of Physical-Geographical Regions and a Scheme of Floristic Zoning of Middle Povolzh’e

Abstract

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.
