Abstract

Morphological and molecular studies show that many species classified in Psychotria L. subgen. Heteropsychotria Steyerm. belong to other genera, as Margaritopsis C. Wright, Carapichea Aubl., Notopleura (Oerst.) Bremekamp, and to Palicourea Aubl. (Andersson 2001, 2002a, b, Nepokroeff 1997, Nepokroeff et al. 1999, Razafimandimbison et al. 2014, Taylor 2001, 2005, Taylor and Gereau 2013). In the Flora Mesoamericana a large amount of the species classified originally as members of the subgen. Heteropsychotria are treated in the frame of the first mentioned genera but 70 species and 2 subspecies remained in the Psychotria L. (Taylor 2012). They were distinguished as members of the subgenus Heteropsychotria, although 23 of them were transferred earlier to Palicourea Aubl. (Borhidi 2011). Recently Borhidi and his coauthors revised the fruit and seed morphology of the Mexican and Meso american Psychotria and Palicourea species and described two new genera having different pyrene types and flowers (Borhidi et al. 2015). To complete the list of the Mesoamerican species belonging to Palicourea Aubl. subgenus Heteropsychotria Steyerm. 35 new combinations are made.
