Trees, to 27(-30) m, d.b.h. to 70 cm. Stipules 5.5-8.5 cm. Petiole 2.5-4 cm; leaf blade broadly elliptic to oblong, 8.5-16 × 5-10 cm, base cuneate, apex ± blunt to ± acute. Inflorescences 2-4(-8)-flowered cymes; peduncle 2-5 cm. Flowers sessile. Calyx lobes ovate, 9-14 × 5-7 mm. Petals lanceolate, 7-9 mm, fleshy, partly embracing stamens, margins pilose. Stamens 8, 4 borne on base of petals, 4 borne on sepals, 6-8 mm; anthers sessile. Ovary emerging far beyond disk, free part elongate-conic, 2-3 mm; style 0.5-1.5 mm. Fruit dirty brownish green, elongate-ovoid, 5-7 × 2.5-3.5 cm, basally often tuberculate, apically slightly contracted. Hypocotyl cylindric, 30-60 cm. 2n = 36.
A much branched large shrub or moderate sized tree, up to 10 m tall, supported on adventitious prop roots from stem and branches with reddish brown bark. Leaves with 1-3 cm long, stout petiole; lamina broadly elliptic or oblong-elliptic to oval, (6-) 8-15 (-20) cm long. (3.5-) 4-8 (-10) cm broad, cuneate at the base, entire, apical mucro 5-9 mm long, upper surface bright green but lower with minute, reddish-black lenticular dots, glabrous; stipules 4-6 cm long, minutely rugulose, acute. Peduncles 4-many-flowered, usually longer than the petioles, borne in axils of leaves of same year, 4-6 cm long, bearing 2-3 flowered cymes. Flowers on 4-8 mm long, rugulose, upwardly thickened pedicels; bracteoles orbiculate, 1.5-2.5 mm long, apically truncate. Calyx tube 2-3 mm long, lobes pale-yellow, narrowly ovate, lanceolate, 10-15 mm long, keeled. Petals yellowish-white, oblong, nearly as long as calyx lobes or slightly shorter, densely villose on margins, sparsely hairy on back and within. Stamens almost sessile, anthers 6-8 mm long, apiculate. Ovary ovoid with free conical portion protruding beyond disc; style inconspicuous, stigma 2-lobed. Fruit ovoid, 4-5 cm long, 2-3.5 cm in diameter, dull brown-green. Hypocotyle rugose, 20-40 cm long, 1.5-2 cm broad.
