Abstract

Some associations of dryas tundras including асс. Dryadetum octopetalae (Du Rietz 1925) Nordh. 1955 in zonal tundra of the Murmansk Region, асс. Stereocaulono paschalis-Dryadetum octopetalae ass. nov., асс. Salici reticulatae-Dryadetum octopetalae ass. nov., асс. Pediculari oederi-Dryadetum octopetalae (Andreev 1932) nom. nov. and асс. Dryado octopetalae-Caricetum arctisibiricae Koroleva et Kulyugina in ChytrD et al. 2015 in the Pechora Lowland and foothills of the Pai-Khoi are described. A new alliance, Dryado octopetalae-Caricion arctisibiricae (Koroleva et Kulyugina 2010) Koroleva in Chytrý et al. 2015, with diagnostic taxa Dryas octopetala (dominant), Carex arctisibirica (dominant), Salix reticulata, Pedicularis oederi, Saxifraga hieracifolia, S. hirculus, Eritrichium villosum, Hedysarum arcticum, Ranunculus monophyllus, and аss. Dryado octopetalae-Caricetum arctisibiricae Koroleva et Kulyugina in Chytrý et al. 2015 as a type, is proposed in the East European tundra.
