Vulnerable in Ivory Coast. Unknown status in Guinea-Bissau, Nigeria and Sierra Leone Distribution Overview Primarily Cameroon, though also may be present in Guinea-Bissau and Central African Republic. It is generally found in the lowland rain forests (sometimes on river banks.) Heartwood Color Brown Red Pink Reddish brown Pale red to pink Mostly indistinct in color from sapwood Darkens slightly upon exposure Sapwood Color Brown Red Pink Pale pink Not clearly differentiated from heartwood Bright orange red to reddish brown Grain Even Closed Figure Straight Wavy Fiddleback (figure) Mottled (figure) Occasionally wavy Mottled figure Generally straight, but not always Fiddleback figure Bee's Wing Texture Fine Coarse Medium Medium to coarse Fine Luster High Medium Lustrous Natural Durability Perishable Non-durable Vulnerable to attack by fungi and termites Very little natural resistance Odor Has a taste Odor similar to cedar No specific taste Silica Content Siliceous Sometimes siliceous Kiln Schedules T6-D4(4/4);T3-D1(8/4) US Schedule E; United Kingdom Drying Defects Discoloration Seasons without checking or twisting Prone to blue stain during initial stages of drying Ease of Drying Rapidly Reconditioning Treatement Rapid extraction, conversion and drying is recommended Dries rapidly and well, with little degrade or defect Tree Size Bole length is 20-30 m Tree height is 50-60 m Trunk diameter is 100-150 cm Product Sources The ITTO reports that timber production from this species is in low quantities. Exports are more or less regular. Exportation of the timber from Cameroon is prohibited by local laws.

Compression strength parallel to grain, or maximum crushing strength, is medium. It is lower in this property than Teak. It resists denting and marring about as well as white oak or birch Numerical Data Item Green Dry English Bending Strength 7771 11508 psi Density 34 lbs/ft3 Hardness 975 lbs Maximum Crushing Strength 4165 6357 psi Stiffness 1078 1401 1000 psi Specific Gravity 0.37 0.42 Weight 52 31 lbs/ft3 Radial Shrinkage 4 % Tangential Shrinkage 7 % Volumetric Shrinkage 12 % Item Green Dry Metric Bending Strength 546 809 kg/cm2 Density 544 kg/m3 Hardness 442 kg Maximum Crushing Strength 292 446 kg/cm2 Stiffness 75 98 1000 kg/cm2 Specific Gravity 0.37 0.42 Weight 833 496 kg/m3 Radial Shrinkage 4 % Tangential Shrinkage 7 % References Bolza, E., Keating, W.G.,1972,African Timbers - the Properties, Uses and Characteristics of 700 Species,C.S.I.R.O.
