DESCRIPTION DE L'ARBRE
Description botanique
It is a small to medium-sized, occasionally fairly large tree up to 40 m tall. The bole is straight, cylindrical, branchless for 18 m, with diameters of 80 cm. Sometimes steep buttresses up to 3 to 5 m or, rarely, stilt roots are present.
Habitat naturel
It is often found in secondary rain forests, at low to medium altitudes. It grows in a wide range of habitats, including coastal forests and swamp forests, in ultrabasic soils.
IDENTIFICATION DU BOIS
