Abstract
The analogues of Pleistocene tundra-steppe (mammoth steppe) vegetation are shown to dwell in Altai arid high mountains (plateau Ukok): contemporary tundra-steppes and cryophytic steppes prevail in low part of alpine belt. Within fl oristic classification framework tundra-steppe communities were ascribed to class Carici rupestris-Ko bresietea bellardii Ohba 1974, cryophytic steppes - to class Cleistogenetea squarrosae Mirkin et al. 1992. New alliance Stellario petraeae-Festucion tschujensis Makunina was outlined. It unites cryophytic steppes of South Siberia mountains.
