A new chasmophytic taxon of the Campanula ser. Garganicae Trinajstić (Campanulaceae) from the island of Vis (Croatia)

The amphi-Adriatic and Western Balkan region is floristically extremely rich, among other, comprising at least 85 species and subspecies of the genus Campanula L. Among them, morphologically and phylogenetically well separated is amphi-Adriatic group of nine taxa belonging to the Campanula sect. Campanula subsect. Elatines (Wohlfarth) Trinajstić ser. Garganicae Trinajstić. In the course of floristic researches on the island of Vis, a new taxon belonging to the Campanula ser. Garganicae was discovered. This new taxon grows as a member of the endemic chasmophytic vegetation of the Centaureo-Campanuletalia Trinajstić 1980. From the morphological point of view the new taxon, because of the campanulate corolla is similar to the species Campanula portenschlagiana Schult., whereas regarding the shape of leaves, type of hairs and indumentum it is similar to the Ionian species C. acarnanica Dambolt and C. cephallenica Feer. We used nuclear ITS and plastid trnL-trnF DNA sequence data to address the question of the phylogenetic position of this new taxon inside the ser. Garganicae. The previously unrecognized entity from the island of Vis was identified as a phylogenetically and morphologically separate taxon from all other taxa within the ser. Garganicae and showed closer relationships with C. debarensis Rech. f. and C. cephallenica Feer.
