Molecular phylogeny of the Campanula pyramidalis species complex (Campanulaceae) inferred from chloroplast and nuclear non-coding sequences and its taxonomic implications
The Campanula pyramidalis complex is a group of closely related taxa with a distribution across the Balkans, from the Gulf of Trieste in the north to the Peloponnese Peninsula in the south, with small disjunct parts of the range in the south Apennines. Although 21 taxa were described within this complex, only three, C. pyramidalis, C. versicolor, and C. secundiflora, have been generally accepted in recent synoptical taxonomic treatments. Our molecular phylogenetic analyses based on sequences of three non-coding chloroplast regions (psbA-trnH, psbZ-trnfM, trnG-trnS) as well as of nuclear ribosomal internal transcribed spacers (nrITS), lend strong support to the recognition of several lineages which only partially correspond to generally accepted taxonomic concepts. Molecular data presented in this study showed that C. pyramidalis is a polyphyletic assemblage that segregates into three distinct lineages, one of which is described here as a new species, C. austroadriatica sp. nov. The lectotype of C. pyramidalis, redefined in a strict sense, is designated. Neither C. versicolor nor C. secundiflora were found to be strictly monophyletic, but their monophyly could not be rejected. Morphological and biogeographical implications are discussed.
