CITES(EU) status of protection. Not protected.

Geographic distribution. Tropical Africa. Tropical regions of Central- and Westafrica (Ivory Coast, Ghana, Nigeria, Equatorial Guinea, Gabun, Congo, Angola, Zaïre, Uganda).

Growth rings, colour, grain, etc. Growth ring boundaries distinct (demarcated by often indistinct (little colour contrast) marginal parenchyma bands visible only with a lens on clean end grain surfaces). Heartwood basically brown to red; without streaks. Sapwood distinct from heartwood colour (grey to pinkish and commonly very wide). Odour indistinct or absent. Wood of medium weight (0,44–0,52–0,59 g/cm3). Interlocked grain present (producing a more or less pronounced ribbon figure on quarter-sawn faces).

Hardwood vs softwood. Vessels (pores) present (= hardwood).

Vessels (pores). Wood diffuse-porous. Vessels (pores) arranged in no specific pattern; in multiples; commonly in short (2–3 vessels) radial rows. Vessels large (140–170–220 µm); very few to few (2–4–8). Tyloses absent. Other deposits in heartwood vessels (pores) present (red brown), or absent (in case sapwood is mistaken for heartwood).

Axial parenchyma. Axial parenchyma present; banded. Parenchyma bands exclusively marginal (or seemingly marginal); narrow. Other macroscopically visible types of axial parenchyma: vasicentric.

Rays. Rays narrow; of uniform size. Large rays commonly less than 1 mm high.

Storied structure. Storied structure absent.

Resin canals. Normal resin canals absent (occasional occurrence of resin canals are of traumatic origin).

Physical and chemical tests. Heartwood not fluorescent. Water extract not fluorescent; colourless to brown (to reddish or brownish). Heartwood extractives not leachable by water. Ethanol extract fluorescent (yellowish); colourless to brown, or red. Froth test positive (a faint ring of foam persists). Splinter burns to partial ash; colour of ash white to grey.
