The trees are large, reaching heights of up to 25 or 30 m, with trunk diameters of 50 to 90 cm. The boles have commercial lengths of about 15 m. The tree has a strong cumarin scent. In Brazil, this species is reported to occur in Northeast region in the areas known as caatingas. In Peru, it is also found in well-drained soils of the dry tropical forests. In Bolivia it is found in lowland rain forests and semideciduous forests.
