The present study aims to improve the knowledge of Simaroubaceae in the Reserva Ducke, Manaus, Amazonas. It is based on morphological analysis of herbaria collections and field expeditions. The family is represented in that area by six species belonging to four genera: Homalolepis (1 sp.), Picrolemma (1 sp.), Simaba (3 spp., including a new one described herein), and Simarouba (1 sp.). Identification keys, morphological descriptions, illustrations, and taxonomic comments are provided for each species.
