The present work aims to describe and characterize the leaf architecture and venation patterns of the species Manilkara huberi (Ducke) A. Chev and Manilkara paraensis (Huber) Standl. The collection of botanical material for the two species was carried out in the Bosque Rodrigues Alves, located in the municipality of Belém-PA, from each individual were made exsicates and later confirmed the species, through specialized literature and comparison between the botanical material collected and gifts in virtual herbaria. After the identification, in the laboratory of Morfo-Anatomia Vegetal was carried out the diaphanization for analysis of foliar architecture. The species analyzed in this study had characteristics in common venation of 1st category pinnate, veins of 2nd category brochidodromous and uniform angulation, veins of 3rd category alternate alternating, veins of 4th category regular polygonal reticulated, presenting larger order of veins. The veins of 3rd category differ between species in the angulation, while M. huberi is acute, M. paraenses presents obtuse angle. Fifth category veins are absent in M. huberi, while the 5th category vein of M. paraenses is of the dichotomous type. The species presented veins of up to fifth order and alternate tertiary percorrents. The venules (F.E.V.s) were of the simple and branched type with a single branch, appearing to be a significant character for the separation of the species. The analysis of Sapotaceae species allowed the observation of taxonomic characters important for a possible differentiation among the studied species. The Sapotaceae family is characterized by the presence of veins of the second type of brochidodromous type
