For the pas ten years there has been a discussion about the phylogenetic placement of the small genus Diclinanona amongst Annonaceae researchers. Recently, several parties involved in the discussion teamed up in order to investigate the issue and settle the discussion. The resulting paper of Erkens et al. in the December issue of Taxon not only fixes Diclinanona firmly in the Annoneae (as sister to a clade with Disepalum, Annona and Asimina) but also presents a complete online revision of the three species.

A new tropical tree species of Guatteria has been described in Phytotaxa 2014, 173(2): 149-156. Guatteria darienensis can be found in Panama and Colombia and is named after the Darién Gap (Tapón del Darién), the road-free and difficult to access area between Panama and the Colombian Chocó, where most collections were made.
