Abstract

The results of the inventory of wild plants in the territory of O.V. Fomin Botanical Garden in 2021 are given. For the needs of the research, an online project "Biota of the O.V. Fomin Botanical Garden (Kyiv)" has been launched. Historic milestones and latest achievements in the study of spontaneous flora of the Botanical garden are characterized. The tendency towards the increase in number of vascular plant species is noted. Specifically, in the middle of the 20th century there were reported 220 species of vascular plants for the Botanical garden territory, in the early 21st century there were 245 species (2005) and 314 species from 215 genera and 65 families (2008). In 2015, 347 species from 223 genera, 67 families, 4 classes and 3 divisions were noted. According to the results of the study in 2021, 115 new plants were found by the authors of the article in spontaneous flora of the Botanical garden. The list of new taxa, their habitat and date of discovery, as well as the authorship of the findings are given. For the first time, 4 taxa of alien plants were found for the flora of Ukraine: Arabis procurrens, Lactuca sibirica, Polanisia dodecandra subsp. trachysperma and Talinum paniculatum. Their main morphological, taxonomic and geographical characteristics are briefly described, information on the naturalization of these taxa in other countries is given. For the first time for the flora of the Right-Bank Forest-Steppe and the urban flora of Kyiv the following are given: Cymbalaria muralis, Cyperus glomeratus, Phedimus stoloniferus, Ranunculus acris subsp. friesianus, Tradescantia × andersoniana. Additionally, during the research there were identified 29 introduced plants with high naturalization rates that need further monitoring. Their list and features of naturalization are given. According to the results of the study, a complete list of the spontaneous flora of the O.V. Fomin Botanical Garden includes 524 taxa from 291 genera and 71 families.
