*African walnut, tigerwood, Congowood, brown mahogany (En). *Noyer d’Afrique, noyer du Gabon (Fr).

*Evergreen large tree up to 45 m tall; bole branchless for up to 25(–30) m, usually straight and cylindrical, sometimes sinuous, up to 120(–200) cm in diameter, slightly thickened at base or with short buttresses; bark surface greyish brown to blackish brown, smooth to scaly, with many lenticels, inner bark pinkish red with whitish streaks, fibrous, with strong sweet smell; crown dense, dark green; twigs glabrous. *Leaves alternate, paripinnately or imparipinnately compound with (5–)10–15 leaflets, glabrous; stipules absent; petiole 3–9 cm long, channelled and slightly winged, rachis 4–20(–30) cm long; petiolules 2–10 mm long; leaflets opposite to alternate, elliptical to oblong-lanceolate, 5–25 cm × 2–10 cm, cuneate to rounded at base, obtuse to acuminate at apex, leathery, pinnately veined with closely spaced lateral veins. *Inflorescence an axillary or terminal panicle up to 40 cm long, glabrous. *Flowers functionally unisexual, regular, 4-merous; pedicel 1.5–3 mm long, jointed; calyx lobed almost to the base, 1–2 mm long; petals free, elliptical, 4–6.5 mm long, white, tinged greenish or reddish; male flowers with stamens fused into a cup-shaped tube with 8 anthers at margin, ovary not functional; female flowers with superior, globose ovary, 4-celled, gradually passing into the style, stigma head-shaped, stamens not functional. *Fruit a pendulous, tetragonal capsule 4–7 cm × 1–1.5 cm, black, dehiscing with 4 valves, many-seeded with seeds attached to the top of the central column. *Seeds 4–6 cm long including the large apical wing. *Seedling with epigeal germination, but cotyledons often remaining within the testa; hypocotyl 3–4 cm long, epicotyl 2–3 cm long; first 2 leaves opposite, with 2 pairs of leaflets.

*Growth rings: 2: growth ring boundaries indistinct or absent. *Vessels: 5: wood diffuse-porous; 13: simple perforation plates; 22: intervessel pits alternate; 23?: shape of alternate pits polygonal; 24: intervessel pits minute (<font size="1">≤</font> 4 μm); (25: intervessel pits small (4–7 μm)); 30: vessel-ray pits with distinct borders; similar to intervessel pits in size and shape throughout the ray cell; 42: mean tangential diameter of vessel lumina 100–200 μm; 47: 5–20 vessels per square millimetre; 58: gums and other deposits in heartwood vessels. *Tracheids and fibres: 61: fibres with simple to minutely bordered pits; (65: septate fibres present); 66: non-septate fibres present; 69: fibres thin- to thick-walled. *Axial parenchyma: (76: axial parenchyma diffuse); 78: axial parenchyma scanty paratracheal; 79: axial parenchyma vasicentric; (80: axial parenchyma aliform); (81: axial parenchyma lozenge-aliform); 83: axial parenchyma confluent; (84: axial parenchyma unilateral paratracheal); 92: four (3–4) cells per parenchyma strand; 93: eight (5–8) cells per parenchyma strand. *Rays: 98: larger rays commonly 4- to 10-seriate; 104: all ray cells procumbent; 106: body ray cells procumbent with one row of upright and/or square marginal cells; 114: <font size="1">≤</font> 4 rays per mm; 115: 4–12 rays per mm. *Secretory elements and cambial variants: 131: intercellular canals of traumatic origin. *Mineral inclusions: 136: prismatic crystals present; 142: prismatic crystals in chambered axial parenchyma cells.
