The aim of the present paper is to get a deep insight into the taxonomy of the species belonging to Centaurea subgenus Acrolophus with special concern to the sect. Dissectae (Hayek) Dostál. Stress should be laid on the considerable ecological uniformity characterizing this subgenus. In fact, almost all of the taxa belonging to it very frequently occur in calcareous rocky habitats. An attempt to assess the status of taxa within the sect. Dissectae has been made in comparison with the treatments by Fiori and later Pignatti. In conclusion two intraspecific taxa of earlier authors raised to specific rank resulting in one new name being proposed.
