The authors present the most important floristic data of Tolna and Baranya coun­ties, col­lected together or separately in the last 15 years, or observed by other data providers. In total, occur­rence data of 140 taxa are reported. Most of them are protected species in Hungary, but the list also includes rarer weeds (Ado­nis flammea, Althaea cannabina, Aphanes arvensis, Bunias orientalis, Legousia speculum-veneris, Vicia lutea) and adventive species (Helminthia echioides, Oxybaphus nyctagineus, Rubia tinctorum). Several species of phytogeographical importance were also found in the forest-steppe vegetation of the loess areas studied. Occurrence of Linaria biebersteinii should be highlighted. L. biebersteinii is a very rare species in the Transda­nubian region, and is no longer found in Europe west of this region. The occurrence of Himantoglossum adriaticum is a new contribution to the flora of the southern Transdanubian region.
