Centaurea crocata , described in 1984 from the Serra de Monchique in the Algarve (S Portugal), has a long history of confusion with C. prolongi from S Spain. From the study of herbarium specimens and of living plants, authors conclude that all previous Portuguese citations of C. prolongi belong actually to C. crocata . However, authors' studies confirm the real presence of C. prolongi in some relictic localities in the limestones of the extreme south of the Algarve. A morphologic comparison between the two species is performed and authors suggest for C. crocata a hypothetical hybrid origin between C. prolongi and a species of sect. Chamaecyanus .
