On the identity of a Centaurea population on Procida island, Italy: Centaurea corensis rediscovered / Hilpold, A; López Alvarado, J; Garcia Jacas, N; Farris, Emmanuele. - In: PLANT BIOSYSTEMS. - ISSN 1126-3504. - 149:6(2015), pp. 1025-1035. [10.1080/11263504.2014.983578]
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.
