Tree, 5–35 m. high, unarmed. Leaves sessile, those of larger trees sometimes petiolate; lamina medium to dark green above, paler beneath, when dry greenish, medium to dark brown, paler beneath, brittle, often thinly papyraceous to coriaceous, narrowly or very narrowly obovate, in young plants usually narrower, 1·75–3·5 (in young plants up to 5) times as long as wide, 15–70 x 7–25 cm., up to 135 x 50 cm. in young plants or low–levelled branches, narrowed to the auricles or long–decurrent into the petiole; veins conspicuous; margin not recurved. Sepals green, rounded, usually spreading when dry, the outer ones circular or broadly ovate, 5–8 x 5–8 mm., when dry rugulose outside and often pointed, the inner ones usually slightly larger. Corolla in the young bud rounded or tapering, in the mature bud 5–10 as long as the calyx, 35–60(70) mm. long, tapering at the apex, white, the limb paler than the tube which is slightly greenish outside; tube 3·8–6·5 x as long as the calyx, 1·25–2·5 x as long as the lobes; lobes 11–13, very narrowly elliptic, spreading or recurved. Berry ellipsoid, when dry irregularly shrivelled, conspicuously rugulose, acuminate.
