Abstract
The paper presents the results of botanical-geographical analysis of Thymus L. species in the flora of western regions of Ukraine. The study of current thyme distribution on this territory shows that a significant part of the identified species is confined to the Transcarpathian lowland, Ukrainian Carpathians, Pre-Carpathians and the southwestern part of Podillya height. Here is located one of the centers of Thymus diversity in Ukraine. Distribution of the range-bordered species within the studied area has been clarified: Th. serpyllum L. emend. Mill., Th. pannonicus All., Th. glabrescens Willd., and Th. alternans Klokov. It was revealed that Thymus species in the flora of western regions of Ukraine are featured in relatively high variety of geographic range types. Based on the zonal characteristics, altitudinal breakdown, and regional distribution patterns, the species with temperate-submeridional, plain, and European types of range, respectively, are predominant. According to the climate affinity, the ranges of most Thymus species in this area are inclined towards regions with oceanic climate. Thus, thyme species composition in western regions of Ukraine shows closer affinity to thyme diversity in the flora of Central Europe than of the eastern and south-eastern regions of Ukraine. The analysis of geographical elements shows the dominance of species belonging to the mountain type of geoelements.
