This study characterizes the anatomical structure and physical properties of 11-year-old Schizolobium amazonicum Ducke (pashaco) wood associated with cacao in an agroforestry system located in the province of Lamas, department of San Martin, Peru. The anatomical variation in three axial levels and three radial levels of the shaft, and the physical properties in the axial levels were described as a basis for the knowledge of its technological behavior of the species according to its age as an alternative for the forestry industry. The studied Wood presented white color, cross-grain, medium texture, medium gloss and satin veining. Diffuse porosity, solitary and multiple radial pores, with large tangential diameter (219m), 2 pores/mm2 and 225m length, classified as small. It has vasicentric and aliform parenchyma, homocellular rays, libriform fibers, non-stratified, short (1291m), diameter of 37m, wall thickness of 2.3m. Near the pith, lower values of pore diameter were found at the three levels of the stem, lower values of fiber length at the base and center of the stem, and lower values of wall thickness at the base and apex. Near the bark, a higher value of fiber length and a lower value of fiber diameter were obtained in the basal zone of the stem. No significant differences were found in the physical properties at the three axial levels studied. The species presented radial shrinkage (CR) of 2.55%, tangential shrinkage (CT) of 5.84%, volumetric shrinkage (CV) of 8.19%, T/R of 2.4 and basic density (DB) of 0.32.
