The Lecythidaceae family is one of the most populous in tropical forests, having greater concentration in the Amazon Forest mainly due to the adaptive capability of its flowers. It has a high economic importance in the Amazon region, presenting 28 species with timber potential, however, despite its economic value there are few studies about Lecythidaceae. The present study aimed to carry out the macromorphological characterization of the stem, leaf architecture and using the diaphanization technique to characterize the leaf nerve pattern of four species belonging to Lecythidaceae, which are Couratari stellata (A.C.Sm.), Eschweilera collina (Eyma), Eschweilera coriacea ((DC.) S.A. Mori) and Eschweilera pedicellata ((Rich.) S.A.Mori), collected in the Tapajós National Forest. As for the characters evaluated for the shaft, the obtained results were: straight base (3) and buttresses base (1); aspect of dirty and rough rhytidome (4). As for leaf architecture apexes acuminated (3), acute (1); round base (1) coined (2) and obtuse (1); entire margin (3) and crenate (1) were observed. Regarding the leaf nerve pattern, all species presented pinnate primary vein and bachidodrome secondary vein. The macromorphological characteristics in conjunction with the nerve pattern help in the process of species recognition in floristic surveys.
