Studies on variations in cell sizes of tree species in tropical climate are scarce. Thus, the aim was characterize the radial variation of basic density and wood anatomy of Astronium graveolens Jacq. Five specimens were collected at the Luiz Antônio Experimental Station, (SP). Standard methods for studying the density and wood anatomy were employed. According to the results we observed high correlation among basic density, fiber length, fiber wall thickness, vessel diameter and vessel frequency with distance from the pith. The wood density is highly dependent on fiber length, fiber wall thickness and vessel diameter, there was an increase towards the pith to bark.
