Seven species previously placed in Neisosperma Raf. are now included in Ochrosia. The names Ochrosia section Echinocaryon F. Muell. and Ochrosia section Ochrosia are applied for the fibrous-fruited species and cavity-fruited species of Ochrosia, respectively. Neisosperma Raf. is reduced to Ochrosia section Echinocaryon F. Muell. Separate keys are given for the species of both sections.
