英文摘要	Stitchwort polster (Stellaria pulvinata Grub.) is an endemic species with local distribution in the arid regions of Central Asia-the Mongolian Altai highlands (2500-3800 m above sea level). This species forms an endemic alpine cryophyte -herb-polster formation that is divided into three classes and ten groups of associations. Stitchwort is dominant and codominant in cryophyte -herb polster communities. In cryophyte -herb-sedge-kobre-sia polster communities, this species changes its presence from significant to minor, with moderate abundance. Cryophyte -herb-gramineous polster communities are widespread and have the highest coenotic diversity. Cryo -petrophyte polster communities with Stellaria pulvinata play an important role in the vegetation cover of the central part of Mongolian Altai. They do not form a separate high-rise belt but are found in the composition of the vegetation cover of two high-rise belts, the cryophype bunchgrass steppe belt (2800-3200 m) and the cryophyte kobresia and sedge tundra belt (3200-3500 m). They are also sporadically found in the subnival belt (3500-3800 m). At the level of microcombinations, the vegetation cover structure contains serial ranks of polster communities on the mountainsides and polster complexes with herb-gramineous communities on the peneplanation surfaces and alpine moraines. Exposition combinations of phytocatenae with cryophyte-herb polster communities and cryo-phyte-bunchgrass steppes with stitchwort occur at the level of meso-combinations.
