Campanula aureliana (Campanulaceae), a new species from Albania

Campanula is a species-rich genus with high variability of the morphological traits, controversial taxonomic treatments within the Mediterranean basin as a species diversity centre. One of the monophyletic groups in the genus is the Campanula series Garganicae Trinajstić distributed in the amphi-Adriatic and Ionian region. The group as currently delimited encompasses 11 taxa, mostly with highly restricted distributional ranges. In the present study Campanula garganica Ten. var. albanica Markgr. (=C. aureliana) is described and illustrated as an isophyllous species from central Albania. The results of phylogenetic analyses based on nuclear ITS and chloroplast trnL-trnF data support C. garganica var. albanica as a clearly distinct taxon within the Campanula ser. Garganicae. Its description is given, and diagnostic morphological and SEM seed micromorphological characters of closely related species are compared and discussed. Morphologically C. garganica var. albanica shows close affinity with C. fenestrellata Feer, mainly for the habit, shape and size of the corolla, but differs in a lot of significant features. Information on the ecology and conservation status of the newly described taxa is presented. A taxonomical treatment is provided as due to nomenclature rules, a new nomenclatural combination, Campanula aureliana, is proposed.
