Description Of The Tree
Botanical Description
It is a dominant tree, it can reach a height of 30 to 45 m, with a diameter of up to 150 cm, but more commonly about 40 to 100 cm. The bole is free of branches to about 25 m or more. It develops large buttresses up to 3 m tall.
Natural Habitat
Terminalia amazonia is found in primary tropical rain forests. In the Amazon basin it is reported on terra firme forests, on well drained soils.
Natural Distribution
This species is reported to extend from southern Mexico into northern South America to Bolivia and Peru.
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels solitary and in short radial multiples. Tangential diameter of vessel lumina 150 to 200 micras (medium). Occasionally white deposits in heartwood vessels. Occasionally tyloses common. Vessels per mm2 10 to 20 (abundant). Simple perf Occasionally axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally axial parenchyma aliform. Occasionally axial parenchyma confluent. Prismatic crystals in non-chambered axial parenc Rays more than 10 per mm (abundant). Rays exclusively uniseriate. Prismatic crystals in the ray cells. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Fibers with simple to minutely bordered pits.

Workability
Sawing
The timber is reported to be fairly difficult to saw.
Blunting Effect
Blunting effect on tools is reported to be very severe.
Planing
Straight-grained material is reported to be easy to plane, but material with interlocked grain may tear in planing. Reduced cutting angles are recommended for better results.
Turning

Nailing
Nailing requires pre-boring.
Gluing
The wood glues well.
Sanding
Sanding characteristics are rated as good.
Polishing
The wood can be polished to a smooth finish.
Response To Hand Tools
This species responds poorly to hand tools.
Substitute Species
