Abstract

The reorganisation and new circumscription of the gigantic genus Psychotria started with the classic article of Nepokroeff and co-authors in 1999, based on molecular phylogenetic studies. Its statements and suggestions were followed by the separations and modifications of different genera, as the extension of Margaritopsis by Andersson in 2001 and C. M. Taylor in 2005, revalidation and extension of Notopleura by C. M. Taylor in 2001, the new circumscription of the genus Psychotria by Andersson, in 2002, and revalidation of Carapichea by C. M. Taylor in 2012. The major modification of the neotropical Psychotria was the union of the Palicourea and the Heteropsychotria subgenus of Psychotria (Steyermark 1972) suggested by Nepokroeff and co-authors mentioning that this change would provoke the transfer of about 250 neotropical Psychotria species. This process started with the article of C. M. Taylor and co-authors in 2010, followed by Borhidi in 2011 and further changes are forecast by C. M. Taylor in the Flora Mesoamericana (2012). The mentioned modification concerning mainly the species of the Mexican and Mesoamerican flora and some species of wider neotropical distribution. In the Antillean floras Palicourea and Psychotria are treated according the traditional concept of Alain (Cuba in 1962, Hispaniola in 1995) and the monographs of C. M. Taylor in 1988, and 1989. In the recent paper the authors publish the first results of the taxonomic revision of the Psychotria s. l. species of the Cuban and Hispaniolan flora proposing 4 new combinations and a short actualised review of the taxa concerned the former corrections listed above.
