The city of Abakan is an urban district, the capital of a constituent entity of the Russian Federation of the Republic of Khakassiya, with a population of 171.2 thousand people. According to the botanical and geographical zoning of L. M. Cherepnin, the city of Abakan is located in the Pryabakan valley steppe (S1) in the central part of the Khakass-Minusinsk basin at an altitude of 250 m above sea level at the mouth of the river Abakan. Despite the fact that the territory of the Republic of Khakassia has been sufficiently studied botanically, information on the current state, structure and species composition of the flora of the city of Abakan remains far from complete, which served as the basis for in-depth studies of its vegetation cover. The aim of the work was to identify the flora of the city of Abakan and new and rare species of plants in it. Floristic fees in the city were held from 2016 to 2019 by the method of model areas (MA) of the urbanized landscape. For the Republic of Khakassia, as a result of field studies of 11 MA within the administrative borders of the city of Abakan, new and rare plant species were found and first identified: 1 new species for Siberia (Potentilla pimpinelloides L.), 2 new species for the Republic of Khakassia (Dianthus deltoides L., Potamogeton obtusifolius Mert. et WDI Koch.) And additional locations for 6 rare species in the city of Abakan (Lilium pumilum Delile, Oxytropis ammophila Turcz., Rosa spinosissima L., Stuckenia filiformis (Pers.) Boern., Taraxacum bessarabicum (Horn) Hand.-Mazz., Myricaria bracteata Royle.).
