Nomenclatural notes and typifications in campanula versicolor (Campanulaceae) and related names

Campanula versicolor is a member of the Campanula pyramidalis complex. It is distributed in the southern Balkan Peninsula, with a small disjunct range in SE Italy (Puglia and Basilicata administrative regions). Due to its high morphological variability, 17 taxa have been described (at specific and infraspecific level). However, the taxonomic status of these taxa is not clear. In modern floristic literature and checklists they are considered as synonyms within broadly defined C. versicolor. Considering the fact that misinterpretations of their taxonomy in floras and checklists might be caused by unresolved nomenclatural issues, after studying the original material from relevant herbarium collections, we designated lectotypes or epitypes for the following names: C. corymbosa, C. planiflora, C. plasonii, C. rosanii, C. tenorei, C. versicolor, C. versicolor f. mrkvickana, C. versicolor subsp. thessala subvar. lancifolia, C. versicolor var. rosanii, C. versicolor var. thessala, C. versicolor var. thessala f. tomentella, C. versicolor var. tomentella and C. willdenowiana. Note on the already typified C. mrkvickana is also provided.
