Viola chelmea and Viola jooi (Violaceae), new species for the flora of Serbia and their distribution in the Balkan Peninsula and the Carpathians

During several botanical expeditions in the Republic of Serbia (Mts Sar- Planina and Mts Homoljske Planine), two species of the genus Viola (V. sect. Viola) were found as new for the flora of Serbia: Viola chelmea Boiss. & Heldr. in Mt. Osljak and V. jooi Janka in Mt. Vukan. The last taxon represents a new species also for the flora of the Balkan Peninsula. The taxonomic positions, phytogeographic importance and conservation statuses of the two new plants is discussed within the scope of their newly established distribution patterns both in the Carpathians and the Balkan Peninsula.
