Eugenia speciosa is a tree 5-12 m high from Atlantic Forest in southern and southeastern Brazil. It is common in rainforests and "restingas" . This species also occurs in montane Atlantic Forest in Minas Gerais State (Brazil) and also occurs in Paraguay, Argentina, Uruguay and Bolivia. This species has leaves with visible, salient dots on both faces, glabrous, obtuse apices with cartilaginous margins and a glabrous hypanthium. The lectotypes chosen for Phyllocalyx limbatus and Phyllocalyx macrosepalus are from BR; they were seen and we consider that the specimens that well represent the names. The lectotype that was chosen for Phyllocalyx limbatus is a specimen that is a duplicate (isotype) of the specimen that was in B which was destroyed in the Second World War. For thus, we consider it as the lectotype for this species.
