Salsola paulsenii (Chenopodiaceae) is reported for Kyiv: several plants were found (September 2017) in a sandy ruderal area of the northwestern part of Obolon, along railway tracks leading to the grain elevator and brewery facilities of the Obolon Joint-Stock Co. Some co-occurring plants may represent hybrids of S. paulsenii and S. tragus. Data on morphology and distribution of S. paulsenii and related species are provided. If established, this species may become an invasive weed in Ukraine. Recent changes in taxonomy and nomenclature of Salsola sensu lato are discussed. Nomenclatural information is provided for species of the Ukrainian flora formerly reported in Salsola sensu lato and now placed in Salsola sensu stricto (incl. Kali), Soda, Caroxylon, Climacoptera, and Pyankovia.

Keywords: Salsola, Kali, Chenopodiaceae, Salsoloideae, nomenclature, taxonomy, floristic record, alien species
