BIOMORPHOLOGICAL ANALYSIS AND OCCURANCE OF ENDEMIC AND RELICT SPECIES OF THE CHECHEN REPUBLIC.

This article provides a biomorphological analysis and occurrence of endemic and relict species of the Chechen Republic. Endemic species (taxa unique to a particular geographical area) are characteristic elements of local biodiversity. Narrow endemics occupy isolated habitats, often associated with limited ranges of ecological conditions or small common geographic ranges. The analysis is based on the processing of herbarium materials and field observations of the authors. [ABSTRACT FROM AUTHOR]
