A large woody creeper or liana. It is a climbing plant. It is very variable. It can grow 20-100 m long. The stem can be 1 m around. Young twigs have rusty hairs. The leaves are thinly leathery. The leaf blade is 8-12 cm long by 3-5 cm wide. It is oblong with a short tip. The base is rounded. It is glossy above and mat underneath. The flowers are white or cream coloured and have a sweet scent. The fruit are the size of an orange. They can be 15 cm across. They have a reddish-brown woody shell. The pulp is acid and sweet. The seeds are 10-18 mm long. The plant varies a lot.
Corolla tube 6–6·5 mm. long, swollen in the upper half but the wall not thickened, constricted at the mouth, puberulent on outer surface and pubescent internally above the stamens; corolla lobes 2–3·5 x 1–1·5 mm., elliptic, subglabrous on outer surface and glabrous within.
Upper surface glossy, brownish-green when dry, glabrous, midrib impressed, other nerves raised or level; lower surface mat, pale brownish when dry, lamina glabrous or sparsely pubescent near the petiole, midrib subglabrous to hispid, all nerves raised.
Liane climbing to 12 m. or more; young twigs ferrugineous-pubescent, indumentum later becoming greyish, rather persistent; bark on young branches dark reddish brown with tiny circular white lenticels.
Leaves thinly coriaceous; petiole c. 5 mm. long, pubescent all round; lamina 7·5–11·6 x 3–4·4 cm., oblong, apex shortly acuminate, acumen rounded, base rounded.
Calyx 2–2·5 mm. long, lobes broadly elliptic, densely appressed ferrugineous-pubescent, the indumentum characteristically parted along the median line.
Inflorescences terminal many-flowered capitate or lax cymose panicles on peduncles 0-1·8 cm. long; axes densely ferrugineous-pubescent.
Stamens inserted in the upper part of the tube so that the anthers reach to 1 mm. of the mouth; anthers subsessile, c. 0·75 mm. long.
Ovary c. 0·5 mm. high, compressed-globose, pubescent; style, clavuncle and stigma 3–3·5 mm. long.
Fruit up to 15 cm. in diameter, globose, yellow or green turning brown, inedible.
