Leaves petiolate, blade elliptic to ovate or obovate, 1.9–14.5 cm long, 0.8–6 cm wide, obtuse to bluntly acuminate at the apex with acumen up to 1 cm long, rounded to cuneate at the base, sometimes slightly ciliate, glabrous above, lower surface completely glabrous or pubescent at the base of midrib and lower secondary veins; petiole 1.5–8 mm long, glabrous or pilose, with 4–8 triangular glands on each node, often with empty bracts in between nodes.. Inflorescence terminal, sometimes also axillary, 1.6–5.5 cm long, 2–20-flowered; peduncle 5–33 mm long, sometimes tendril-like, elongate and curved; bracts ovate to triangular, 1–2.5 cm long; pedicels 1.2–6.5 mm long.. Flowers fragrant; sepals ovate, 1.2–3.1 mm long, rounded at the apex; corolla white, creamy or yellow; tube often greenish, occasionally tinged pink or reddish, 6–12 mm long; lobes narrowly ovate to elliptic, 5.3–15.5 mm long, 1.9–4 mm wide, glabrous, rounded; stamens inserted 1.8–3.6 mm from the base of the tube, included for 1.3–5.9 mm; ovary ovoid, glabrous or with a few hairs.. Fruits green with white or light brown verrucose spots, 1–50 mm in diameter, globose or pyriform, 2.5–6 cm long, 2–20-seeded; pericarp 5–6.5 mm thick; pulp fleshy, white, turning yellow when exposed; seed up to 17 mm long, irregularly ovoid, laterally compressed, minutely pitted.
More
A liana or climbing shrub. It grows 25-40 m high. The stems are 25 cm across. The stems are deeply fluted, looking like ropes. The bark is brown with grey spots. The leaves are thin and 5-12 cm long by 2-5 cm wide. The lower leaf surface has shallow cracks. It often has tendrils. The flowers are at the ends of stems and in the axils of leaves. They can be a few to many flowers. The flower tube is white and there is pink under the lobes. The fruit are 8-10 cm across and edible. The seeds are 8-17 mm long.
Leaves membranous, drying brownish green, usually not strongly discolorous; petiole 3–8 mm. long, glabrous or pubescent, often rugose, deeply channelled and often folded into a tube; lamina (4)5–12(14) x (1·5)1·7–5 cm., ovate-or elliptic-oblong, the apex cuspidate-attenuate into a short round-tipped acumen, the base acute to rounded.
Corolla white, the tube and reverse of lobes tinged pink or yellow; corolla tube 7·5–9 mm. long, slightly widened in the middle at the level of the anthers, outer surface glabrous or sparsely hairy; corolla lobes narrowly elliptic, ± as long as tube, glabrous.
Upper leaf surface mat or somewhat glossy, completely glabrous; midrib rather wide, scarcely channelled; secondary and tertiary veins impressed so that the surface bears a reticulum of shallow cracks.
Lower surface completely glabrous or with pubescent midrib; midrib prominent, lateral nerves sometimes raised, tertiary reticulation level with surface, easily seen with a hand-lens.
Inflorescences terminal and axillary few-to several-flowered cymes or racemes, forming dense clusters or frequently elongating and becoming tendrillous; axes glabrous or pubescent.
Calyx of 5 strongly imbricate ovate sepals 1·5–2 mm. long, united at the base, glabrous with minutely ciliate margins, c. 1/5–1/4 as long as corolla tube.
Stems deeply fluted “like a bundle of parallel ropes”; bark brown with grey spots.
Ovary 1 mm. high, conical, glabrous; style, clavuncle and stigma 1·5–2 mm. long.
Stamens inserted at the middle of the corolla tube; anthers 1·5–1·75 mm. long.
Flowers subtended by 2 sepal-like bracteoles, strongly jasmine-scented.
Scandent shrub or liane attaining up to 40 m. with support from trees.
Fruits up to 10 cm. in diameter, globose.
Young stems glabrous or hispidulous.
Seeds 8–17 mm. long.
Tendrils common.
