Classification of relic steppe communities in the Omolon valley (Western Chukotka) has been performed according to the Braun-Blanquet approach. All communities represent 3 associations, 3 subassociations, 3 variants and 15 communities of class Сleistogenetea squarrosae Mirk. et al. 1986, order Helictotrichetalia schelliani Hilbig 2000 and alliance Elytrigio jacutori—Dracocephalion palmati Sinelnikova 2009. The new association — Lychnido sibiricae—Festucetum kolymensis ass. nov. and two new subassociations — Thymo diversifolii—Elytrigietum jacutori festucetosum kolymensis subass. nov. and Dracocephalo palmati—Saxifragetum omolojensis eremogonetosum tschuktschori subass. nov. are described. Peculiarities of distribution of class Сleistogenetea squarrosae in the North-East of Russia are discussed.
