Abstract
Campanula leblebicii Yıldırım (Campanulaceae) is described here as a new species. Diagnostic morphological characters, a full description, and detailed illustrations are given herein. C. leblebicii is restricted to the Çaldede Mountain in Kemalpaşa district of İzmir Province in western Anatolia, Turkey. According to its morphological features, it belongs to Campanula L. subgenus Campanula section Rupestres (Boiss.) Charadze. It shows morphological and ecological similarities with C. mugeana Yıldırım, belonging to C. section Quinqueloculares (Boiss.) Phitos., and to C. koyuncui Duman and C. teucrioides Boiss. belonging to C. section Rupestres. However, C. leblebicii is easily distinguished from these taxa, especially by its glabrous habit; stigma, 3-lobed, and capsule, open by 3 basal valves, shiny, and never concealing by enlarged appendages (from C. mugeana); smaller calyx appendages; capsule never hidden by enlarged calyx appendages, and habitat phyllite-schistose rocks (from C. koyuncui); entire leaves, calyx appendages minute, never enlarged after anthesis (from C. teucrioides).
