Sapwood surface corrugated. A thin, cream layer normally visible under the subrhytidome layer before the first section of the outer blaze.


Lateral veins curving inside the blade margin. Compound leaf rhachis with a median ridge running along the upper surface at least on the leaflet bearing section. Leaflet stalks swollen and transversely wrinkled. Leaflet blades about 6-19.5 x 2.8-5.5 cm. Domatia are small foveoles.


Calyx about 2 mm long, puberulous. Petals subrhomboidal, about 2 mm long. Disk +/- yellow in colour. Anthers pubescent.


Fruits 1 or 2-lobed, about 5-15 mm diam., loculicidally dehiscent. Valve margins pubescent on inner surface. Aril almost completely enclosing the seed.


First pair of leaves usually compound with two leaflets. At the tenth leaf stage: leaflet blades elliptic or narrowly elliptic, apex acute or acuminate, base cuneate or attenuate, slightly unequal-sided, foveoles small and inconspicuous (visible with a lens); midrib raised on the upper surface; terminal bud clothed in short, pale, prostrate hairs. Seed germination time 21 to 97 days.
