An update to the species list of vascular plants of the spontaneous flora of the Left Bank Forest-Steppe of Ukraine

Data on findings of seven species of vascular plants that are new records for the spontaneous flora of the Left Bank Forest-Steppe zone of Ukraine are presented. Four species (Artemisia umbrosa, Sedum album, Ribes aureum, and Prunus tomentosa) are alien plants completely naturalized in the studied area; other three species are treated by author as representatives of the indigenous fraction (Cerastium kioviense, Rhododendron tomentosum, and Vicia lathyroides). Cerastium kioviense and V. lathyroides are considered not rare species in the studied region but rather overlooked by botanists due to their early flowering period. Four species (A. umbrosa, C. kioviense, R. aureum, and P. tomentosa) were for the first time found in Poltava Region, two species (R. aureum, P. tomentosa) – in Kharkiv Region, and one (V. lathyroides) – in Kyiv Region. For all reported species, lists of their localities, places of original descriptions and nomenclatural types are indicated. The species name Prunus tomentosa is lectotypified.
