DESCRIPCIÓN DEL ÁRBOL
Descripción botánica
The trees are reported to reach heights of 30 to 37 m, with trunk diameters ranging from 60 to 90 cm. They develop well-formed and cylindrical boles that are up to 18 m long, with well developed buttresses, sometimes 4.5 m tall.
Hábitat natural
This gregarious species is reported to be dominant, developing on the lowlands. It is usually found in homogeneous stands called "morales" on swampy areas and gallery forests. It has an abundant natural regeneration.
IDENTIFICACIÓN DE LA MADERA

TRABAJABILIDAD
Aserrado
The timber is reported to saw with moderate difficulty but it yields smooth surfaces. There may be considerable pick-up and chipped grain if the material contains interlocked grain.
Corte de chapa rotativa
It is not suitable for plywood because of its high density.
Chapa tranchada
It is not suitable for plywood because of its high density.
Pérdida de filo_romado
It exerts a moderate blunting effect on the cutting elements.
Cepillado
The timber is reported to plane with moderate difficulty because of interlocked grain. A reduced cutting angle of 20 degrees is recommended.
Torneado
30
Clavado
Good nail-holding, pre-boring is necessary.
Encolado
The behavior in gluing is fair.
Lijado
The material is reported to sand with moderate difficulty.
Acabado
This wood yields a smooth surface in finishing.
Doblar al vapor
Bending properties are reportedly moderate.
