For description see Field Mus. Publ. Bot. 13 (4) [Fl. Peru]: 680.1958. this species is known to me from the original specimens only. It is included in this papaer because of the possibility of confusion with Eugenia patrisii, E. roseiflora and E. cribrata. Although E. aerosa is known only from the upper Amazon, in Peru and adjacent Brazil, it may eventually be found in the Orinoco drainage.
