This paper contains a short report about new and unpublished chorological data for the following species: Hydrocharis morsus-ranae L., Bidens cernuus L., Najas marina L., Potamogeton lucens L., Schoenoplectus triqueter (L.) Palla, Cyperus rotundus L., Polypogon monspeliensis (L.) Desf. and Paspalum distichum L.. Despite the fact that this paper provides insight into the distribution of analyzed species, it could be used as a base for invasive species’ Paspalum distichum L. expanding patterns research, and as a base for reevaluation of the threatened status of Schoenoplectus triqueter (L.) Palla and Cyperus rotundus L. in Serbia.

Based on presence of area types and area groups, the phytogeographical analysis show that Rogozna Mt. is area with eurasian-submediterranean-centraleuropean-pontic characteristics. Eurasian area type is dominant in the flora of Rogozna Mt. Detailed analysis of the Eurasian area type showed a numerous presence of the species with Central European-Mediterranean (73) and Central European-Mediterranean-Pontic (73) types of distribution. The influence of the Mediterranean region is especially pronounced. There are 117 species with Mediterranean-Submediterranean type of distribution, many of which are endemics or subendemics. Typical Pontic elements of flora are present in very low percent (1.27%), but taxa with Mediterranean-Pontic (14.7%) and Central-European-Mediterranean-Pontic (9.38%) are numerous. The presence of an imposing number of endemic taxa (51) has a great significance from the aspect of biodiversity and conservation of the area.

As a result of the two-year investigation of the Rogozna Mt. flora, 795 plant taxa (species and subspecies) belonging to 337 genera and 77 families were recorded. Floristic analysis of investigated area was performed in comparison to the floristic data of Serbia, Balkan peninsula and neighboring region of Rogozna Mt. (Ibar river valley and high mountain region of Kopaonik Mt).

The flora of the karst plateau Tepoš, which is the part of Vidlič 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 Tepoš 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 Tepoš 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.

As a result of two-year investigation of the Miljkovacka gorge flora, carried out during the 2010. and 2011., 331 plant taxa belonging to 245 genera and 70 families were recorded and sorted into 112 floristic elements, 15 area groups and 9 area types. Phytogeographical analysis showed that the species of Eurasian area type are the most abundant ones.
