Centaurea lovricii, a new tetraploid (2n = 4x = 36) species is described and illustrated from the island of Vis in central Dalmatia (Croatia). It occurs on calcareous cliffs near the sea with NW exposition, together with several other rare endemic species. Its morphological features, distribution, ecology, conservation status and taxonomical relationships are here examined. As concerns its morphology, it is closely related with endemic C. glaberrima Tausch and C. divergens Vis. of Centaurea sect. Centaurea, from which it differs in having more succulent leaves with larger and less incised leaflets, larger capitula, larger phyllaries, with appendages more developed, provided with denser and undulate fimbriae, larger florets, and larger achenes, with longer pappus.
