The flora of the karst plateau Tepo?, which is the part of Vidli? mountain (eastern Serbia) was studied. Based on the analysis of the collected material and data from the literature, it was noted that the flora of Tepo? plateau is represented by 486 species, distributed in 284 genera and 68 families of vascular plants. The biological spectra was shown. The hemicriptophytic-terophytic character was established by analyzing the presence of plant life forms. By phytogeographical analysis the presence of 25 area types was established. The euroasian florystic chorion with 258 species of eurasian area type is the most abundant, followed by mediterranean-submediterranean (58 species), central-european (47 species), cosmopolitan (27 species) and pontian area type (24 species). In the flora of Tepo? plateau the 9 balkan endemic taxa were recorded, which is 3,14% of total balkan endemic taxa in flora of Serbia. A small number of endemic taxa is expected, considering the low diversity of habitats. Balkan endemic taxa recorded in this area are: Acer hyrcanum subsp . intermedium, Bupleurum flavicans, Crucianella graeca, Eryngium palmatum, Pastinaca hirsuta, Hypericum rumeliacum subsp . rumeliacum, Thymus praecox subsp . jankae, Linaria rubioides subsp . nissana and Viola tricolor subsp . macedonica .
