More
A woody creeper. It can grow 35 m long and be 50 cm around. It has many branches. It can climb by tendrils. The leaves are 6-14 cm long by 3-8 cm wide. They are narrowly oval. The veins are raised under the leaf. The veins curve forming a vein near the edge of the leaf. The flowers are in clusters at the top of the plant. The flowers have a sweet scent. The fruit can be 3 cm long by 4.5 cm wide and almost round. They are green, yellow or red. The pulp is yellow. They are edible. The seeds are up to 11 mm long.
Leaves membranous, not strongly discolorous when dry; petiole 3–10 mm. long, glabrous or with a hispid-pilose line along the upper surface; stipules interpetiolar, 1–1·5 mm. long, broadly triangular, inconspicuous, soon disintegrating or caducous; lamina 5·5-14 x 3–8 cm., obovate, oblong-obovate or elliptic, the apex rounded or with a short obscure to well-marked acumen or rarely slightly emarginate, the base shortly auricled.
Corolla pink or yellowish in bud, becoming white at anthesis with pale to dark pink tube; tube 11–19 mm. long, narrowly cylindrical, slightly dilated in the upper 1/2 – 1/3, glabrous externally, pubescent internally below the stamens; corolla lobes 9–14 mm. long, narrowly linear, strongly contorted, long-ciliate along the inner margin.
Calyx 2–2·5 mm. long, lobes triangular, free to base, glabrous but minutely ciliate, provided with conspicuous glandular auricles at the base of each margin which overlaps to the inside (thus the two inner sepals each has 2 auricles, the two outer have none and the fifth has one).
Upper leaf surface with deeply and narrowly impressed midrib and lateral nerves and prominent vein reticulation, entirely glabrous or the midrib hispid-pilose; lower surface with all nerves raised, glabrous or with midrib sparsely pilose.
Inflorescence a loose elongate terminal panicle of few-flowered cymes with sensitive peduncles; axes glabrous.
Ovary narrowly conical, passing imperceptibly into the style; clavuncle cylindrical; gynoecium 8–10 mm. long.
Leaf venation characterised by strongly looped lateral nerves forming a continuous submarginal vein.
Stamens inserted in the upper 1/3 of the corolla tube; anthers subsessile, 1·75–2 mm. long.
Fruit up to 3 x 4·5 cm., ± spherical, green to yellow or red with yellow edible pulp.
Flowers white, yellow, greenish or orange-yellow, in terminal panicles.
Young stems glabrous or sparsely hispid and glabrescent.
Liane climbing to 15 m. or more; slash white.
Climber up to 100 ft. with tendrils
Seeds up to c. 11 mm. long.
Flowers sweet-scented.
