In this paper six new Neotropical species in four genera are described, viz. Annona oxapampae, Duguetia vaupesana, Guatteria castilloi, G. pachyphylla, G. sanctae-crucis and Pseudoxandra xylopiifolia. Furthermore additional data on four poorly known species of Guatteria (G. denudata, G. glauca, G. modesta and G. terminalis) are added.
