The genus Alchemilla L. In the flora of Sverdlovsk Region

Abstract

Based on own authors' collections and revised collections in herbaria (SVER, UFU, LE, MW, NNSU), checklist of the genus Alchemilla for Sverdlovsk Region (Middle Urals) was compiled. Each species in the checklist was followed by a nomenclature reference, information on type, habitats, distribution in the region by its botanical-geographical areas. 62 species of Alchemilla were registered in the region. Seven species (A. cheirochlora, A. decalvans, A. filicaulis, A. glabricaulis, A. iremelica, A. pseudocalycina, A. tichomirovii) were revealed in the region flora for the first time. For three species (A. argutiserrata, A. sarmatica, A. submamillata) erroneously noted for this flora, the presence in the region was confirmed. A. filicaulis and A. exsculpta are new for Asian part of Russia. The presence of a true A. glabricaulis (as adventive species) was confirmed in the Asian part of Russia. Noted for trans-Urals endemic species A. gorodkovii had been placed to synonyms of east-european A. semilunaris and was listed under corresponding name. Among them, 57 species are found in the mountainous part of the region, 27 species of Alchemilla grow in the cis-Urals area, and 12 species in the eastern plain part of the region. Most of the Alchemilla-species complex of Sverdlovsk Region are plain-mountainous and plain species - 27 and 16 species respectively. Alchemillaspecies complex of the region includes 14 East European species, and 7 species associated with West European mountain systems, 27 species associated with Central Asian mountain systems (22 species of continuous and 5 of disjunctive ranges). As for soil moisture factor, mesophytes (17 species) prevail. Most of the species are the components of meadow (29 species), marginal-meadow (10 species) and meadow-steppe (5) communities. 18 species, distributed in the highlands of the Northern Urals, were attributed to the group of alpine-meadow species. An original key has been made to identify 62 Alchemilla-species, occurring in Sverdlovsk Region. © 2019 Altai State University. All rights reserved.
