The paper provides the systematic analysis on highland Alpine rocky-scree vegetation of the Central and Eastern Caucasus. In taxonomy the vegetation under consideration is characterized with domination of dicotyledonous, specific family-species spectrum (Caryophyllaceae-species and Fabaceae-subspecies), a great number of pseudomonotype genera in the main plant families and emuotypic genera, and a low plant genus index. Over half plant genus in the vegetation includes one species - 90 (57.0% of total genus species, whereas, genuinely monotypic there are 4 plant genera: Pseudovesicaria, Symphyoloma, Trigonocaryum and Pseudobetckea, referred to endemic Caucasus plant genera. The main index in the vegetation taxonomy is the ratio between monotypic plant genera in the spectrum of the main plant families that highlights the prominent role in formation of the highland Alpine rocky-scree vegetation of big plant families, namely Asteraceae, Poaceae and Brassicaceae. In the Central and Eastern Caucasus vegetation the big and medium plant families have the determined order: Asteraceae ?Poaceae?Brassicaceae?Ranunculaceae?Caryophyllaceae?Fabaceae?Apiaceae ?Gentianaceae ? Scrophulariaceae ?Cyperaceae ?Rosaceae ?Campanulaceae ?Saxifragaceae.
