Resumo: 	The Monimiaceae is represented in the Neotropical region by six genera. Macropeplus Perkins is a Brazilian genus comprising four species restricted to high-montane Atlantic Forest areas, which have not been properly examined from the anatomical point of view. This study characterizes the anatomical structure and histochemical aspects of the leaves of Macropeplus dentatus and M. ligustrinus, and adds to our taxonomic knowledge ofthe genus. The individuals studied were collected in the Serra dos Órgãos National Park and in the Caraça Natural Park in southeastern Brazil. Among the characteristics common to the two species, hypostomatic leaves, dorsiventral structure, paracytic stomata, a subepidermal layer, collateral vascular system in the form of an arc in the petiole, semicraspedobrochidodromous venation, and the presence of prismatic crystals were registered. Intracellular metabolites, such as phenolic compounds, lipids and mucilage, were identified. The petiole shape, occurrence and distribution of secretory cells and brachysclereids, in association with other morphological features, were relevant to species identification.
