Contribution to the "Atlas of the Russian Flora": Twelve local floras of European Russia.

Background: The purpose of this dataset is to deliver to a wider audience in the form of GBIF-mediated data vast floristic materials collected by the author across various localities of European Russia from 2001-2019 (Arkhangelsk, Tver, Vladimir, Tula, Lipetsk, Voronezh Oblasts, Krasnodar Krai, City of Moscow and Komi Republic). Taxonomic data on vascular plants for ten locations were mobilised from the papers and technical reports published in Russian and standardised. Floristic treatments for two locations (Yasnaya Polyana and Tsaritsyno) have never been published before.

New Information: The newly-prepared dataset includes 5,309 species records, i.e. one species record per each local flora. These are either native or alien (fully naturalised and casual) species. All records within one local flora have the same centroid coordinates and coordinate uncertainty in metres. Floristic inventories from the following locations were mobilised: 01. Ustya, Arkhangelsk Oblast (543 species, 1,500 km); 02. Zaseki, Tula Oblast (593 species, 60 km); 03. Polibino, Lipetsk Oblast (553 species, 70 km); 04. Khrenovoye, Voronezh Oblast (665 species, 200 km); 05. Troyeruchitsa, Tver Oblast (501 species, 10 km); 06. Man-Pupu-Ner, Komi Republic (182 species, ca. 300 km); 07. Middle Lyaga, Komi Republic (143 species, ca. 300 km); 08. Utrish, Krasnodar Krai (933 species, 195 km); 09. Yasnaya Polyana, Tula Oblast (236 species, 2.2 km); 10. Bogolyubovsky Lug, Vladimir Oblast (289 species, 1.7 km); 11. Tsaritsyno, City of Moscow (359 species, 5.3 km); 12. Patakino, Vladimir Oblast (312 species, 1.1 km). According to the GBIF taxonomic backbone, the dataset covers 1,806 species, 669 genera and 127 families of tracheophytes.
