Climber, usually rampant, 0.2-4.0 m high; hairs patent-crisped or short and stiff. Leaves broadly ovate, apex acute to rounded, pubescent especially on lower venation; petioles short, articulated. Inflorescences terminal on twigs, 3-flowered; pedicels up to 15 mm long. Flowers scented. Calyx with tube up to 3 mm long, 5-lobed. Corolla white, salver-shaped; tube slender, up to 20 mm long; lobes ± 7, slightly shorter than tube. Stamens 2, included; filaments short; anthers ± 3.5 mm long. Ovary 2-celled with one ovule in each; style filiform, exserted; stigma lobes viscous. Flowering time Nov.-Apr. Fruit a twin berry (one aborting), subglobose, black when ripe.
Leaves coriaceous, sparsely pubescent to glabrous on both faces; lamina 1–6–4·5 x 0·8–3·4 cm., ovate to elliptic or narrowly elliptic, base acute to rounded, apex obtuse or acute, mucronate; venation slightly raised on both surfaces, inconspicuous below; lateral nerves several, the basal ones joining with others before reaching leaf apex.
Climber. Leaves unifoliolate; acarodomatia, if present, in axils of basal or lower veins; petioles articulate in upper portion. Calyx lobes much shorter than calyx tube, very shallow or up to 1.5 mm long, then thickened and conduplicate, apiculate. Flowers white.
Flowers borne on lateral branches in terminal few– (3–4)–flowered racemes and in the axils of upper leaf–pairs, sweet scented; pedicels 9–15 mm. long.
Calyx glabrous or pubescent; tube 3 mm. long; lobes 4–5, represented by minute thickened points or by conduplicate, recurved teeth up to 2 mm. long.
Corolla white, fleshy or thin–textured; tube 17–25 mm. long; lobes 4–7, 10–15 mm. long, elliptic, apex acute.
Stamens inserted in the top half of corolla tube; filaments up to 2 mm. long; anthers 3–4 mm. long.
Acarodomatia present in axils of lateral nerves up to middle of leaf.
Young stems pubescent, glabrescent, older stems with smooth bark.
Petioles 2–5 mm. long, articulated at about the middle.
Style either exserted from tube or c. 1/2 as long.
Fruit with lobes subglobose, c. 7 mm. long.
Shrubby climber.
