Dacryodes caparuensis, D. decidua, D. froesiana,D. oblongifolia, D. oblongipetala,D. obovata, D. ramosa,D. spatulata, D. sudyungasensis, and D. villosa are described and illustrated. While presenting diverse morphologies, all are lowland species of Amazonia and the Guianas, with the exception of D. sudyungasensis from montane forests on the eastern slopes of the Andes in Bolivia. The descriptions of most of these species are based on few collections. The decision to proceed with the publication of a long-accumulating backlog of novel taxa is based on two factors making it doubtful that additional material of these species will be seen in the near future. First, Dacryodes species are usually rare where they occur, moreover they are usually large trees whose flowers and fruits are difficult to see and access. Second, there has been an alarming decrease in botanical exploration, while the urgency of documenting flora – especially undescribed diversity – has only increased.

Dacryodes caparuensis, D. decidua, D. froesiana,D. oblongifolia, D. oblongipetala,D. obovata, D. ramosa,D. spatulata, D. sudyungasensis, y D. villosa son descritas e ilustradas. Aunque presentan diversas morfologías, todas son especies de tierras bajas en la Amazonía y las Guianas, excepto D. sudyungasensis, de bosques de montaña en los vertientes orientales de los Andes in Bolivia. Las descripciones de la mayoría de estas especies se basan en pocas colecciones. La decisión de proceder con la publicación de estos taxa que llevaban mucho tiempo acumulados se basa en dos factores, a partir de la presunción de que son pocas las posibilidades de que en un futuro cercano haya disponibilidad de material adicional. Primero, las especies de Dacryodes son usualmente raras, más aún considerando que son grandes árboles cuyas flores y frutos son difíciles de observar y acceder. Segundo, nos encontramos ante un decrecimiento alarmante de exploraciones botánicas, mientras que la documentación de la flora – especialmente la diversidad sin describir – se ha incrementado.
