Blaze odour like sugar-cane (Saccharum officinale) and resembling that of Beilschmiedia bancroftii. A thin pale brown layer generally visible beneath the subrhytidome layer before the first section of the outer blaze. Sapwood surface may be corrugated.
Leafy twigs somewhat angular in transverse section. Leaf blades about 4.7-14.2 x 2.5-6 cm, green on the underside, clothed in tortuous, brown, erect and appressed hairs when young but glabrous at maturity. Midrib and lateral veins depressed on the upper surface of the leaf blade. Generally 4-6 main lateral veins. Petioles channelled on the upper surface. Numerous small oil dots visible with a lens but not to the naked eye.
Inflorescence paniculate, scarcely exceeding the leaves. Flowers often emitting an unpleasant odour. Lower half of the perianth tube glabrous or pubescent on the inner surface. Tepals about 1.3-1.7 mm long, pubescent on the outer surface. Ovary usually glabrous, but sometimes pubescent towards the apex. Style pubescent.
First pair of leaves usually opposite or subopposite, ovate or lanceolate, about 65-110 x 30-50 mm, green on the underside. At the tenth leaf stage: leaf blade glabrous on the upper surface, oil dots small. Petiole grooved on the upper surface with a few short pale hairs on the undersurface.
