Other Common Names: Kokrodua (Ghana), Assamela (Ivory Coast).


Distribution: West Africa, but mainly Ghana and the Ivory Coast, gregarious, grows in both wet and dry areas.


The Tree: May reach a height of 150 ft; bole somewhat irregular, clear to 90 to 100 ft, buttressed to 8 ft and then fluted; trunk diameters 3 to 6 ft.


The Wood:

General Characteristics: Heartwood yellow brown turning to a dark brown on exposure sapwood narrow, lighter in color and clearly demarcated.  Texture moderately fine; grain straight to interlocked; some resemblance to teak.


Weight: Basic specific gravity (ovendry weight/green volume) 0.57; air-dry density 43 pcf.


Mechanical Properties: (2-cm standard)

Janka side hardness about 1,560 lb for dry material.  Amsler toughness 166 in.-lb at 12% moisture content (2-cm specimen).


Drying and Shrinkage: Dries rather slowly with little degrade apart from slight warp. Kiln schedule T10-D5S is suggested for 4/4 stock and T8-D4S for 8/4.  Shrinkage green to ovendry: radial 3.0%; tangential 6.4%; volumetric 10.7%.  Movement in service is rated as small.


Working Properties: Works well with hand and machine tools, finishes cleanly, turns satisfactorily, good gluing, moderate steam-bending properties.  Sawdust reported to be an eye irritant, good ventilation needed.


Durability: Heartwood is rated as very durable and highly resistant to termite attack.  Dark stains liable to appear if in contact with iron under damp conditions.


Preservation: Heartwood extremely resistant to preservative treatments; sapwood fairly permeable.


Uses: Boatbuilding, joinery, flooring, furniture, decorative veneers, considered an excellent teak substitute.
