Other Common Names: M'bonda (Cameroon), Niove, M'boun (Gabon), Kamashi, Nkafi (Zaire).
Distribution: Found in Gabon, Cameroon, and the Congo region; occurs in mixed forests, in large stands, as well as secondary forests.
The Tree: Reaches a height of 70 to 100 ft; bole is cylindrical, straight and clear to 60 ft; butt is sometimes swollen; trunk diameter to 3 ft.
General Characteristics: Heartwood red brown to yellow brown with darker streaks; sapwood 4 in. wide, pale yellow to orange brown. Texture is very fine; grain straight; slightly lustrous and occasionally oily; pepperlike scent.
Weight: Basic specific gravity (ovendry weight/green volume) 0.75; air-dry density 57 pcf.

Amsler toughness 155 to 272 in.-lb at 12% moisture content (2-cm specimen).
Drying and Shrinkage: Seasons slowly and requires care to avoid end checking, little warp. No information on kiln schedules. Shrinkage green to ovendry: radial 5.5%; tangential 7.2%; volumetric 12.5%. Movement in service is small.
Working Properties: Timber saws slowly but with little difficulty, tungsten-carbide tipped cutters are suggested; planes with ease to produce a smooth finish, glues satisfactorily. Should be quartersawn. if steamed, suitable for slicing.
Durability: Excellent durability and resistant to termite attack. Excellent weathering properties.
Preservation: Difficult to treat.
Uses: Cabinetwork, joinery, decorative veneers, flooring, turnery.
