Sažetak
European amphi-Adriatic and Western Balkan region is floristically exceptionally rich, among other, comprising at least 85 species and subspecies of Campanula genus, without many poorly known lower (incipient) taxa and hybrids. Among the most interesting in the region are endemic indigenous lineages, such as "isophylloid" aggregates Campanula Waldsteiniana (C. waldsteinana - C. tommasiniana) and Pyramidalis (C. pyramidalis - C. versicolor - C. secundiflora). Being neither isophyllous nor heterophyllous, but a little bit of both, the Waldsteiniana and Pyramidalis relationships to other campanuloids in the region puzzle botanists for a long time. Comparative morphological and ecological data, isoenzymes, restriction-site variation of PCR-amplified cpDNA fragments and ITS1-5.8S-ITS2- sequences of the nuclear ribosomal DNA were used to provide better insights into these fine relationships. The data were analysed using multivariate statistical and cladistical methods: here are presented the preliminary results, showing that two morphologically distant lineages might be truly relatives after all.
