Abstract. The North Caucasus steppe vegetation is one of the “blank spots” in vegetation classification survey of Russia. Its syntaxonomy is in the early stages of elaboration and represents a new area of research in modern vegetation science. Geobotanical data on the steppes of the North Caucasus are important for analyzing the differences between the steppe vegetation of Europe and Asia and they are necessary for development any comprehensive syntaxonomic and phytogeographical generalizations on the grasslands of Eurasia. This article continues publication of the results of the North Caucasus steppe vegetation research. Geobotanical studies were conducted in June 2022 and May-June 2023 on the Borgustan, Dzhinal and Skalisty Ranges. Geobotanical relevès were based on standard methods. The relevès were placed to the database elaborated using the TURBOVEG program and processed by the Juice program. Syntaxonomical analysis was carried out using the J. Braun-Blanquet approach; the names of the new syntaxa were given in accordance with the “International Code of Phytosociological Nomenclature.” The system of higher syntaxa was given according to the synthesis “Vegetation of Europe…” with additions. Geobotanical studies of the North Caucasus steppe vegetation carried out on the Borgustan, Dzhinal, and Skalisty ranges, and the subsequent syntaxonomic analysis based on the J. Braun-Blanquet approach allowed to reveal a new association Helianthemo nummularii–Caricetum humilis ass. nov. and two new subassociations Helianthemo nummularii–Caricetum humilis typicum subass. nov. and Helianthemo nummularii-Caricetum humilis centauretosum holophyllae subass. nov. Conclusion. The new syntaxa were attributed to the alliance Helianthemo buschii-Elytrigion stipifoliae Lysenko, Shchukina, Neshataeva, Shilnikov et Dutova 2021, the Order Galio biebersteinii-Bilacunarietalia microcarpae Lysenko, Shchukina, Neshataeva, Shilnikov et Dutova 2021, the Class Festuco-Brometea Br.-Bl. et Tx. ex Soó 1947.
