RESEARCH ON PLEUROCARPOUSMOSS SPECIES DISTRIBUTED IN THE TERRITORY OF LERIK DISTRICT

Abstract

The article provides information about the floristic composition of pleurocarpous (leafystemmed) mosses distributed in the territory of the Lerik district of the Republic of Azerbaijan. Information was provided on the morphology and distribution of taxa, and species were analyzed based on substrate and other bioecological characteristics. A total of 60 herbarium specimens of this group of mosses were collected during the expeditions conducted during 2022-2024. According to research conducted in the Lerik district, 20 species of pleurocarpous moss belonging to 7 families and 13 genera have been discovered in the district. In the territory of the Lerik district, species belonging to monotypic families that sometimes play a dominant and edificator role in various natural floristic complexes have also been found. They play an important role in the formation of vegetation cover by creating synusiae (Hypnum pallescens - Homomallium incurvatum, Hypnum imponens - Plagiomnium rostratum). Among the identified species, Calliergonella cuspidata (Hedw.) Loeske. and Stereodon plicatulus Lindb, belonging to 1 family and 2 genera, were evaluated as rare species.
