In the present study the anatomical characteristics, radial and longitudinal variation of the anatomical constituents of Calycophyllum spruceanun (Benth) Hook., Of a plantation from the Peruvian Amazon were evaluated. Six trees were used, 3 discs of each tree (base, DAP, apex) were collected; from each one, three positions in the medulla-cortex direction and three positions in the base-apex direction were considered. The anatomical characteristics of the fiber and vessel elements and spokes were described. It was found that fiber length, wall thickness, tangential pore diameter and vessel length increased significantly towards the cortex; while the frequency of pores decreased. In the longitudinal direction, the fiber length and vessel length decreased significantly towards the apex; the frequency of pores increased towards him; The fiber wall and tangential pore diameter showed no significant changes from the base to the apex.
