Other Common Names: Wonton (Ghana), Aye (Nigeria), Kankate (Zaire).


Distribution: Found on the edge of the humid rain forests from Senegal to Cameroon and Gabon; also in dry savanna formations. Widely planted as a shade and farm boundary tree.


The Tree: Reaches a height of 90 to 120 ft, bole straight, cylindrical, about 60 ft in length; trunk diameter 2 to 3 ft, wide-spreading root ridges.


The Wood:

General Characteristics: Heartwood yellow when freshly cut darkening on exposure to a golden- or coffee brown; sapwood wide, grayish white, distinct. Texture fine to moderately coarse; grain shallowly interlocked; moderately high luster.


Weight: Basic specific gravity (ovendry weight/green volume) 0.70; air-dry density 54 pcf.


Mechanical Properties: (2-cm standard)

Drying and Shrinkage: Reported to have satisfactory seasoning characteristics. No information on kiln schedules. Shrinkage green to ovendry: radial 3.3%; tangential 5.8%; volumetric 8.0%. Reported to be rather stable when manufactured.


Working Properties: Works with moderate ease with most hand and machine tools, good sawing characteristics; glues well; takes a good finish; veneers well.


Durability: Heartwood vulnerable to attack by decay fungi and liable to termite attack.


Preservation:Heartwood extremely resistant to treatment; sapwood is moderately resistant.


Uses: Joinery, turnery, flooring, veneer.
