Leaf blades 5.4–15.5 × 2–6 cm, elliptic to narrowly ovate, acute to shortly acuminate at apex, obtuse to rounded or occasionally acute at base, glabrous above and beneath or sometimes sparsely pubescent or pubescent beneath, subcoriaceous, shiny above; midrib straw-coloured when dry, crested above, prominent beneath; lateral nerves in 8–9 main pairs; tertiary nerves reticulate, raised above, obscure or apparent beneath; domatia absent or inconspicuous; petiole 3–6 mm long, the margins and midrib raised above, glabrous or covered with short stiff hairs; stipules triangular at base, acuminate at apex, 7–11 mm long, 4–6 mm wide at base, glabrous or rarely glabrescent outside, mid-nerve apparent.
Inflorescence occasionally borne at the top node, but usually at the next 1–5 nodes down, (3)5–11-flowered, forming compact narrowly pyramidal panicles; peduncles up to 4 mm long, obscured by the stipules; pedicels up to 5 mm long; bracts/bracteoles 7–10(12) mm long, lanceolate or linear-lanceolate, usually subulate above.
Fruit pale brown when dry, green when fresh, flecked with white, 3.5–5.3 × 2.4–3.2 cm, ob-pyriform; calyx limb eventually deciduous.
Calyx glabrous; tube 2.5–3 mm long; limb-tube c. 2 mm long, ± as wide as the tube; lobes (4)5–8 mm long, linear-subulate.
Shrub or small tree 1.5–8.5 m tall; young branchlets somewhat grooved, glabrous or less often glabrescent.
Corolla tube (7.2)9.7–11.4 cm long and c. 2 mm wide; lobes 1–2.2 × 3–5 mm, oblong-lanceolate, acuminate.
Anthers partly exserted, apiculate at apex, scarcely hastate at base.
Pollen presenter 2–2.5 mm long, oblong-ellipsoid, obtuse at apex.
Seeds blackish-brown, 6 mm long, strongly striated.
