The research aimed to characterize the anatomy according to the guidelines established by the International Association of Wood Anatomists - IAWA (1989) and the Brazilian Institute of Environment and Renewable Natural Resources - IBAMA (1991). The wood of 5 year old Eucalyptus grandis x Eucalyptus urophylla trees from Coronel Portillo was evaluated in three longitudinal positions and three radial positions. The anatomical elements, their behavior at the axial and radial levels, and their interaction were assessed. The wood exhibits interlocked grain and medium texture. It has solitary pores, oval-shaped and arranged diagonally; vasicentric paratracheal parenchyma and non-stratified rays. Microscopically, the wood shows unilateral vasicentric paratracheal parenchyma, homocellular rays consisting exclusively of procumbent, uniseriate cells, and non-stratified libriform fibers. There are no differences in the qualitative characteristics, but there are differences in the quantitative characteristics of the anatomical elements between the longitudinal and radial interactions. Axially, the fiber length does not show a defined growth; the tangential pore diameter maintains its growth until the intermediate level and then increases; the fiber length increases towards the intermediate level and then remains constant; the fiber diameter continues to grow until the intermediate level and then decreases towards the apex, while the wall thickness does not show differences in its behavior. Radially, the vessel length does not show a defined growth; the tangential pore diameter maintains its growth until the middle level and then increases towards the bark; the fiber length increases from pith to bark; the fiber diameter does not show significant differences, and the wall thickness increases from pith to bark. The most homogeneous coefficient of variation was found in fiber wall thickness, fiber length, and fiber diameter.
