Tree. Geographic distribution: tropical Africa.

General. Heartwood basically brown to red to yellow, partly with streaks. Sapwood colour distinct from heartwood colour. Density 0.82–0.94–1.04 g/cm³.

Vessels. Wood diffuse-porous. Vessels in multiples, commonly short (2–3 vessels) radial rows. Average tangential vessel diameter 140–225–350 µm. Average number of vessels/mm² 2–5–7. Perforation plates simple. Intervessel pits alternate, average diameter (vertical) 7–10 µm, vestured. Vessel-ray pits with reduced borders or apparently simple, rounded or angular. Helical thickenings absent.

Tracheids and fibres. Fibres very thick-walled. Average fibre length 540–1150–1630 µm. Fibre pits common in both radial and tangential walls, simple to minutely bordered. Fibres non-septate.

Axial parenchyma. Axial parenchyma paratracheal. Paratracheal axial parenchyma vasicentric, aliform, and confluent. Aliform parenchyma lozenge. Axial parenchyma as strands. Average number of cells per axial parenchyma strand 4–7.

Rays. Rays 7–12 per tangential mm, multiseriate (also if only few), 1–2(–3) cells wide. Rays composed of a single cell type (homocellular); homocellular ray cells procumbent.

Storied structures. Storied structure present (rare) or absent, all rays storied, axial parenchyma not storied. Arrangement of tiers irregular. Stratification mostly irregular (wavy) and only macroscopically visible.

Mineral inclusions. Crystals present, prismatic, located in axial parenchyma cells. Crystal-containing axial parenchyma cells chambered. Number of crystals per cell or chamber one. Silica not observed.

Physical and chemical tests. Heartwood fluorescent (green). Water extract not fluorescent; basically colourless to brown or shade of brown, or red or shade of red. Ethanol extract fluorescent (green). Colour of ethanol extract red or shade of red. Froth test positive.
