Description Of The Tree
Botanical Description
The tree is up to 30 to 45 in height, with a bole length of 10 to 16 m, usually irregular, often buttressed. The trunk diameter attains 100 to 150 cm.
Natural Habitat
Erythrophleum suaveolens occurs in moist forests, dense dry forests and along riverbanks.
Natural Distribution
West, Central and East Africa, mainly in Guinea, Central African Republic and Democratic Republic of the Congo.
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 200 micras or more (large). Vestured pits. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits similar to intervessel pits Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma aliform. Prismatic crystals in short chains in chambered axial parenchyma cells. 3 to 4 cells per parenchyma strand. Rays more than 10 per mm (abundant). Rays and/or axial elements irregularly storied. Rays 1 to 4 seriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Non-septate fibers. Fibers with simple to minutely bordered pits.

General Wood Description
Color
The sapwood is yellowish white to pinkish white, it has a thickness of 3 to 6 cm. The heartwood is yellow-brown to red brown, darkening on exposure, it is clearly demarcated.

Grain
The grain is highly and systematically interlocked; special care is needed when drying because of frequent risks of distortion.
Texture
The texture of the wood is frequently coarse.
Natural Durability
Very durable to decay; without preservative treatment. This species is especially suited for all the uses with risks of permanent or long-lasting humidification. Resistant to termites attack. Heartwood is resistant to Lyctus attacks.

Internal Growth Stresses
No residual stresses are reported in this species.
Silica Content
Silica Content: Negligible content of silica is reported. Amounts over 0.05% may affect wood processing. Silica Value: 0.01
Resistance To Impregnation
Nearly impossible to treat with a too much low penetration of the preservative substances.

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. It is recommended to use special tools for cutting.
Planing
Rather difficult; special tools are needed.
Moulding
Moderately easy; tools must be cautiously sharpened.
Boring
Moderately easy; tools must be cautiously sharpened.
Mortising
Moderately easy; tools must be cautiously sharpened.
Nailing
Pre-boring is necessary.
Gluing
Difficult to glue because of high density.
Sanding
Difficult to obtain very good results because of interlocked grain.
Polishing
Needs pre-coating.
Response To Hand Tools
Working with hand tools is difficult.
