The Amazon has the largest diversity in fauna and flora in the world. So much wealth attracts the attention of many who want to preserve and sustainably exploit. To preserve we need knowledge of the species, especially those that produce commercial timber. The wood anatomy is the study of secondary xylem of plants, their structure, organization, functions and characteristics of each cell element, thereby forming a heterogeneous and anisotropic structure. The anatomical study also allows, species lacking reproductive organs (flowers and fruits) can be identified to taxon family or even identifying and distinguishing apparently similar species. Due to the large sale of Amazonian woods, the identification of these species by macro and microscopic characterization of wood are of extreme importance, because the specimens are no longer endowed with vegetative organs (flowers and fruits). The specimens were collected in the Brazilian Amazon, near the capital of Amazonas state, Manaus/AM. The macroscopic and microscopic descriptions followed the traditional methods used in studies of wood anatomy. Based on the anatomy of the species studied has characters that are fundamental to the identity and characteristics of the genre, such as growth indistinct layers, pores visible to the naked eye large, diffuse porosity, vessels with tangential arrangement. Axial parenchyma visible to the naked eye, paratracheal diamond aliform, aliform confluent may occur, rays visible only under 10x lens on cross and tangential planes, with vascular straight lines, in the radial spokes are somewhat mixed. Presence of crystals in radial cells. These macroscopic characteristics when observed may provide identification oreven the distinction of species apparently identical.
