Colors: the heart isYellow to golden-yellow to orange, Yellowishand the sapwoodWhite to yellow, Yellow.The grain isWavy, the textureMedium coarse to coarseand the lusterDull
Natural durability: Susceptible to insect attack, Very durable Odor: Has a grape-like odor
Kiln Schedules: Kiln Drying Rate (in days) is rapid
Kiln Drying Rate: Rapid (<10 days for boards < 32 mm, to <30 days for boards >= 63 mm)
Drying Defects: Slight twist/warp, Splitting Tree Identification: Bole/stem form is cylindrical Comments: General finishing qualities are rated as good General finishing qualities are rated as satisfactory The timber is similar in characteristics to Okoume (Aucoumea klaineana ), Limba (Terminalia superba ), and Obeche (Triplochiton screloxylon ), all from Africa. Blunting Effect: Minimal dulling effect on cutting tools Boring: Moderately easy
Cutting Resistance: Fairly easy to saw Gluing: Moderate gluing properties Mortising: Difficult to mortise

Bending strength (MOR) = medium Soft Shrinkage, Tangential = small Modulus of Elasticity (stiffness) = medium Medium density Hardness (side grain) = very soft Dents or scratches easily Compression strength (parallel to grain) = low The species has medium bending strength in the air-dry condition (about 12 percent moisture content). It is closer in strength to Mahogany than either Teak or White oak, which have higher bending strength. It is weak in compression parallel to grain (maximum crushing strength), and is inferior to Mahogany Bolza, E. and N. H.
