Abstract
Data of floristic records of Acalyphа australis L. (Euphorbiaceae Juss.) in 2018 in Uzhhorod (Ukraine) were report-ed. This is a new alien East Asian species in the Transcarpathian flora. The plants were recorded on the territory of the Biological Department, in front of and on the territory of the Botanical Garden of the Uzhhorod National University. Micropopulations contains over 50 plants: as vegetative which prevail and so generative. These plants were growth in anthropogenic ecotopes in unformed plant communities. Probably, spontaneous invasion of A. australis was started in the region several years ago. The photo of plants and map of distribution in the region are given. Generalized data’s about primary and secondary (North America, northern part of Australia, eastern part of India, Middle and Central Asia, Caucasus, Turkish and Europe) area of the species, its ecological and coenotic characteristics was given. According to field studies and of investigation of Herbaria collection (KW, ODU, DSU, KHER) the information about modern distribution of the species in Ukraine was generalized: the species was collected in the first time in Ukraine in 1981 in Crimea (Sevastopol), it was found in Steppe zone later: Odesa (1999), Kherson and Luhansk (2000), Kamyanske (2006) and Kryvyi Rig (2012). Probably the species invasion and distribution in Ukraine were connected with decorative plants seeds sharing because escaped plants were noted mainly in the gardens and flowerbeds, on the territory of botanical gardens, or ruderal places, etc. Now we observed the tendency of active spread of the species. The plants are characterized by sufficiently seeds (about 100 seeds per one), indifferent to the type of soil, SR-strategy, morphological variability, small allelopathical activity, etc.
