Abstract
The paper presents the analysis of the genusThymusof the flora of the South-East of the North Caucasus. Revealed the total species, compiled an aspect of the genusThymus, and conducted the analysis's bioecological, geographical composition. In the investigated territory, we have registered eightthymusspecies, distributed mainly in xerophilic types of vegetation: steppe, friganoid, alpine, meadow-steppe, and meadow societies.
Highlights
The flora of the Caucasus is rich and original in the presence of endemic, relict elements, which is due to the islet effect and the presence of refugia in high mountain conditions, which always arouses great interest in terms of floristic research
The genus Thymus served as the object of floristic research
Species of the genus Thymus are combined into groups with similar ecology, coenotic relationships and are confined to specific plant communities
Summary
The flora of the Caucasus is rich and original in the presence of endemic, relict elements, which is due to the islet effect and the presence of refugia in high mountain conditions, which always arouses great interest in terms of floristic research. The study area is characterized by high altitudes, a significant length of mountain ranges, orography, various soils, and complex dissected relief. A significant variety of species formed the conditions for uneven distribution of heat and moisture on its territory. One of the exciting groups for floristic research is the genus Thymus L. - the most significant and taxonomically complex genus in the Lamiaceae family. The family includes 236 genera and about 7200 species, distributed almost all over the world [1]
