The integrated analysis of components of flora as method of detection of flora specifics of natural complexes of different level

The integrated analysis of vascular plants, mosses, liverworts and lichens of the Tver region and the natural complexes of different level presented within its territory is carried out. It allowed to open more completely botanico-geographical specifics of florae of fragments of physiographic provinces and areas in which natural boundaries with exposures of carbonate breeds are presented. High level of specificity of florae of natural complexes of different level is caused by their special role in processes florogenesis.
