Campanula cremnophila (Campanulaceae), a new isophyllous species from Croatia

Within the isophyllous group of Campanula ser. Garganicae Trinajstić, represented by species of prevalent amphi-Adriatic and Ionian distribution, a rare new endemic species named Campanula cremnophila is described new to science and illustrated from Pelješac Peninsula and the nearby Elaphite islands of Olipa and Jakljan in southern Croatia. Campanula cremnophila is a chasmophyte growing on calcareous rocky crevices near the sea, showing close relationship with C. garganica from Mt Gargano in southern Italy. Phylogenetic analyses based on nuclear ITS and chloroplast trnL–trnF data emphasized that C. cremnophila is distinct from other species of Campanula ser. Garganicae, forming a subclade with C. garganica and C. poscharskyana. The morphology, SEM microstructure of seeds and pollen grains, taxonomical relationships, ecology, conservation status of C. cremnophila, as well as an identification key including all the species of the Campanula ser. Garganicae are provided.
