Other Common Names: Bimini (Sierra Leone), Dabe, Ndabe (Ivory Coast), Ditsumi (Gabon), Lukienzo (Zaire).
Distribution: Somewhat sporadically from Sierra Leone to the Cameroons and inland to the Congo; found in both deciduous and rain forests, mainly in small groups.
The Tree: Reaches a height of about 90 ft; boles variable, sometimes up to 60 ft; trunk diameters 3 to 4 ft.
General Characteristics: Heartwood pink or red brown; sapwood gray with a copper sheen. Texture fine, generally even; grain interlocked to irregular; numerous pith flecks forming dark lines 1 to 2 in. long.
Weight: Basic specific gravity (ovendry weight/green volume) about 0.50; air-dry density 40 pcf.
Mechanical Properties: (2-cm standard)
Moisture content Bending strength Modulus of elasticity Maximum crushing strength
(%) (Psi) (1,000 psi) (Psi)

Amsler toughness 282 in.-lb for dry material (2-cm specimen).
Drying and Shrinkage: Seasons fairly rapidly without checking or warping. Kiln schedule T6-D2 is suggested for 4/4 stock and T3-D1 for 8/4. Volumetric shrinkage green to ovendry: 11.6%.
Working Properties: Saws well and works easily with hand and machine tools, dresses well, good gluing and finishing properties, good veneer slicing and peeling properties.
Durability: Heartwood moderately durable but liable to some termite attack. Good weathering properties.
Preservation: Heartwood resistant to impregnation, sapwood moderately resistant.
Uses: General construction, furniture, joinery, veneer and plywood.
