Abstract

The herbarium collection of the Uzhhorod National University (Herbarium UU), both the main collection of the flora of Transcarpathia, and the doublet collections of A. Margittai and L. Wagner are very interesting in the regional sense and have both scientific and historical and cultural significance. The herbarium of the Department of Botany of the Uzhhorod National University (UU) was established in 1947. Today, it is stored in the Botanical Garden and has about 107,000 herbarium specimens [4]. The personal collections of L. Wagner and A. Margittai are stored separately. The herbarium collection of the Uzhgorod National University covers mainly the territory of the Ukrainian Carpathians and the Prytisyan lowland and is currently the most complete herbarium collection of the flora of Transcarpathia. In particular, specimens of many species of aboriginal flora are kept in the herbarium, and the collection of regional exotics is particularly interesting. As a result of the analysis of the herbarium materials of the Department of Botany of the Uzhhorod National University, it was established that 469 species were recorded from the territory of the city of Uzhhorod. By the number of species, the families Brassicaceae, Asteraceae, Rosaceae, Fabaceae and Lamiaceae are the most numerous, Caryophyllaceae, Poaceae and Boraginaceae are much smaller. During the audit of the major part of the scientific herbarium of the Botany Department of UzhNU (flora of Transcarpathia), from all the herbarium specimens, those that were collected in the territory of the city of Uzhhorod or its surroundings, which are now included in the administrative boundaries of the city (for example, the villages of Domanyntsi, Dravtsi, Horyany, Radvanka, Radvansky forest, etc.) were selected. Among the found herbarium specimens are species that are now considered highly invasive within Ukraine. It is likely that for some of them the data refer to the first or one of the early findings of wildness (Amorpha fruticosa L., Robinia pseudoacacia L., Acer negundo L., etc.)
