Nomenclatural note.

Tausch (1828) described C. glaberrima from Dalmatia without indicating any precise locality. The herbarium sheet, with three specimens, that we found in PRC has an original herbarium label with Tausch’s handwriting: " Centaurea -?, e Dalmat. Sber. capit: parvus ovoideus divaricatum ". Tausch usually shortened geographical names: "e Dalmat." refers to specimens collected in eastern Dalmatia, while “Sber.” refers to the collector (i.e. Sieber). In addition, he provided a short morphological description. Later, to the same herbarium label, the identification [= C. punctata Vis.] was added. This was probably done by V. Kosteletzky (pers. observ. by curator P. Mraz). The fourth specimen on the sheet belongs to C. spinosociliata and it is correctly identified on a separate herbarium label by A. Hayek. Here we select the central specimen, which fits Tausch’s description, as lectotype for the name C. glaberrima . One year later, Visiani (1829) described C. punctata from Duare [Zadvarje] in Dalmatia. We consulted the type specimen in PAD (PAD - HD02644), which fits Visiani’s description given in the protologue. In fact, the morphology of the specimen perfectly corresponds to Tausch’s description of C. glaberrima . Therefore, we here designate this specimen as a lectotype and include the name C. punctata as a synonym of C. glaberrima .

Distribution.

According to Greuter (2006), Barina et al. (2015) and Nikolić et al. (2015), C. glaberrima is distributed in Albania, Bosnia and Herzegovina, Croatia and Montenegro (Fig. 4 ).
