The discovery on the Island Procida (Gulf of Naples, off the Italian west coast) of a Centaurea population similar to C. corensis, a narrow-range Sardinian endemic hitherto known only from one single locality in Sardinia, is presented here. The identification of the two populations as C. corensis is confirmed by morphological comparison and morphometric analysis, chromosome counts and nuclear ribosomal DNA sequence data. A recent origin of the species through polyploidization is hypothesized. Finally, the possibility that recent anthropogenic dispersal may account for the disjunction is discussed.

Abstract
The discovery on the Island Procida (Gulf of Naples, off the Italian west coast) of a Centaurea population similar to C. corensis, a narrow-range Sardinian endemic hitherto known only from one single locality in Sardinia, is presented here. The identification of the two populations as C. corensis is confirmed by morphological comparison and morphometric analysis, chromosome counts and nuclear ribosomal DNA sequence data. A recent origin of the species through polyploidization is hypothesized. Finally, the possibility that recent anthropogenic dispersal may account for the disjunction is discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
