Description Of The Tree
Botanical Description
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.
Natural Habitat
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.
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels per mm2 5 to 20. Simple perforation plates. Axial parenchyma absent or extremely rare, non visible with magnifying glass (8x). Rays of two distinct sizes. All ray cells upright and/or square. Body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II).
