Upper leaf surface fairly glossy, almost always puberulent when young, glabrescent, or less often glabrous except for the pubescent midrib, very rarely lamina completely glabrous, midrib channelled, lateral and tertiary nerves more or less raised, never impressed; lower surface crispate-pubescent or glabrous except for the appressed-or spreading-pubescent midrib, midrib prominent, other nerves raised or level with surface, tertiary reticulation easily seen with a hand-lens.
Leaves membranous to subcoriaceous, usually drying discolorous with the upper surface much darker than the lower; petiole 2–7 mm. long, pubescent; lamina 2·4–9·2 x 1–3·2 cm., oblong to narrrowly ovate or rarely oblong-obovate, the apex attenuate or cuspidate-attenuate into a short to long acumen, or acumen ± absent, the base rounded to cuneate.
A shrub or woody climber. It is slender and can climb 25 m high. The stems are 1-2 cm across. The plant contains latex. The leaves are small, opposite and narrowly oval or sword shaped. The flowers are small and white or pale pink. They are in groups. The fruit is round and speckled. It is 5-7 cm across. It is edible.
Corolla white, cream-coloured or yellow, darker on the tube and reverse of petals; corolla tube 3·5–4 mm. long, clavate, the wall thickened in the upper half and the mouth very restricted; exterior surface puberulous especially above the calyx; corolla lobes narrowly elliptic, ± equalling the tube, glabrous.
Inflorescences terminal, many-flowered paniculate cymes forming dense clusters or sometimes the branches elongating and becoming tendrillous; axes densely rufous-tomentose or-pubescent.
Stamens inserted at or just above the middle of the corolla tube; anthers subsessile, c. 0·75 mm. long, reaching to base of constricted part of corolla tube.
Calyx c. 2 mm. long, sepals almost free, oblong, greyish-brown, not glossy, ciliate, dorsally glabrous or puberulent, with hispid midrib.
Flowers scented, each subtended by two sepal-like bracteoles and the inflorescence branches by bracts.
Scandent shrub or woody climber. Corolla tube 3-5 mm long, lobes 4-6 mm long. Flowers white.
