Rchb., and Silene L. (Caryophyllaceae). In conformity with ICBN, 12 new infra- specific taxa are described with locus classicus on the territory of Serbia. Also presented are 24 new nomenclatural combi- nations, including several for endemic taxa not present in Serbia. The nomenclature of certain taxa is supplemented by a short taxonomic-chorological review. Results of these studies will be incorporated in the next volume of “Flora of Serbia”.
