Natural Habitat
Endodesmia calophylloides occurs in swamp forests and by rivers, growing gregariously.
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 100 to 150 micras (small). Vessels per mm2 6 to 10 (medium). Simple perforation plates. Vessel-ray pits coarse throughout the ray cell. Paratracheal axial parenchyma scanty and/or vasicentric. Prismatic crystals in non-chambered axial parenchyma cells. Rays more than 10 per mm (abundant). Rays non-storied. Rays exclusively uniseriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Non-septate fibers. Fibers with distinctly bordered pits.

General Wood Description
Color
The heartwood is pink, it is not demarcated.
Grain
Straight or slightly interlocked, sometimes with an influence on further processing operations.
Texture
The texture of the wood is frequently coarse.
Natural Durability
Not durable; important risks of decay attacks at any processing step, from logs up to final products. It must receive preservative treatment. Heartwood is sensible to Lyctus attacks.

Workability
Sawing
Sawing of this species requires powerful equipment.
Rotary Veneer Cutting
Not suitable for veneering.
Sliced Veneer
Not suitable for veneering.
Blunting Effect
Moderate blunting effect; stellited blades for sawing and carbide tools for machining are advised.
Machining
It needs powerful tools for processing. Possible difficulties caused by interlocked grain are reported.
Planing
Moderately easy; tools must be cautiously sharpened.
Moulding
Rather difficult; special tools are needed.
Turning
30
Boring
Rather difficult; special tools are needed.
Mortising
Rather difficult; special tools are needed.
Nailing
Pre-boring is necessary.
Gluing
Glues well if basic gluing technical rules are followed.
Sanding
Easy to perform; it gives good results.
Polishing
Needs pre-coating.
Response To Hand Tools
Working with hand tools is difficult.
