Chorology of Campanula Waldsteiniana (Campanulaceae) Aggregate

Chorological data on the stenoendemic aggregate Waldsteiniana are presented. The Aggregate consists of only two closely related species, Campanula waldsteiniana Schult. and C. tommasiniana C. Koch, clearly separated by their corolla shape, which is quite distinct and unique among the taxa of the family Campanulaceae. The Waldsteinianas most probably evolved in the outer (Adriatic) Dinarids from yet unknown ancestor, considered to be close to both Campanula Isophylla and Heterophylla-groups of the amphi-Adriatic and western Balkan area. A Liburnian-mountainous endemic Campanula tommasiniana is centred in the Mt. Učka plateau (Istria peninsula, Croatia), where it most abundantly grows in the stands of endemic, rock crevice association Campanuletum tommasinianae-justinianae Trinajstić prov., but inhabits as well the rock crevices within the stands of the forest association Seslerio autumnalis-Fagetum s. lat. on the Mediterrarnean-montainous belt at the altitudes up to 1400 m. Campanula waldsteiniana is mainly connected to the diverse limestone-fissure plant communities (i.e. Asplenietum fissi, Potentilletum clusianae, both from the alliance Micromerion croaticae) at the altitudes between 700 and 1650 m in the Velebit, Velika Kapela and Gola Plješivica Mts (Croatia), with several localities in Bosnia and Herzegovina (Mts Ilica, Osječnica and Ljubična– Vjetrenica). Here we present the first report on the recent discovery of C. waldsteiniana in south-western Slovenia (Mt Snežnik, Liburnian karst), which is the northern-most known habitat of that species. According to some older literature data, C. waldsteniana was also observed in the continental part of the northern Croatia (Ivančica Mt). Unfortunately, recent investigation did not confirm those observations. The ecology, phytosociology and taxonomic position of the Waldsteiniana aggregate are briefly discussed, together with the statutory protection requirements.
