South Eastern European high mountains represent the southern distributional limits of several arctic-alpine plant species. In this work, syntaxonomical notes about the composition of Dryas octopetala L. dominated plant communities in the Kosovarian part of Sharri Mts. are provided. Additionally, a comparison with other related plant communities from the region is offered. In order to determine the syntaxonomic position of the plant community which develops in the subalpine belt of the Sharri Mts, 22 relevès made on calcareous bedrock were compared with communities similar in the floral composition. Due to the dominant presence of the species Dryas octopetala and Carex sempervirens, the research community from the massif of Luboten, was compared with the associations Carici-Dryadetum octopetalae Jovanović-Dunjić 1955 and Carex laevis-Carex sempervirens Rajevski 1990. After the made extensive comparative analysis, researched community, showed the greatest syntaxonomic affinity with ass. Carici-Dryadetum octopetalae because of the presence of its characteristic species: Dryas octopetala, Carex sempervirens, Arctostaphylos uva-ursi and Saxifraga paniculata. In the floristic composition of the vegetation relevés made in our research, except that were registered all characteristic species of the association, the dominant presence of the Juniperus communis subsp. nana which define its physiognomy, and presence of species as. Carex laevis and Sesleria nitida should be considered as new subassociation juniperetum nanae subass nova. Obtained phytocoenological relevès belong to the alliance Seslerion rigidae Zoly, of which were registered following characteristic species: Dryas octopetala, Eadrianthus graminifolius, Festuca pancicana, Arctostapyhlos uva-ursi, Helianthemum oelandicum subsp. incanum, and Sesleria tenuifolia. Characteristic feature of communities of alliance is high coverage and constancy of dwarf shrubs (Dryas octopetala & Salix reticulata) and mesophytic low herbs and sedges (Carex laevis, Oxytropis halleri subsp. korabensis, Pedicularis brachyodonta, Myosotis sylvestris). Plant communities of alliance Seslerion rigidae are from small to medium sized assemblages and they occupy xeropphylous high mountain grasslands on calcareous substrates. These plant communities are found at N, NE and E steep slopes (average 20º) of high elevation (1793 up to 2350 m. a.s.l.). Based on the plant species composition, the most abundand life forms are Hemicryptophytes (69%) followed by Chamaephytes (18%); while the most predominant floristic elements are divided between SE-European (18%), Balkan (17%) and Euroasiatic (16%) accordingly. They are characterized with high level of diversity, from 22 relevès were recorded 98 plant species, therefore they shall be regarded as highly valuable natural habitats.
