A climbing or scrambling (doubtfully sometimes more or less erect) shrub, 2.1–6 m. tall; the young branches, the inflorescence parts, the calyces, and the young leaves densely and softly pubescent, later the branches are glabrescent and even quite glabrous, the leaves too probably become less pubescent with increasing age.. Leaves opposite, with simple blades, ovate or oblong-ovate, acute to rounded at apex, rounded or very shortly cuneate at base, at anthesis mostly 1.5–3 cm. long and 1–2 cm. broad but older leaves up to 7 cm. long and 4.2 cm. broad occur, midrib slightly impressed on upper with the main veins prominent on lower surface; petiole 3–10 mm. long, articulated near the base.. Inflorescences terminal to the main and to short lateral branches, generally subcompact, with 1–16 flowers.. Calyx-teeth setaceous, 6–7 mm. long; calyx-tube 2–3 mm. long.. Corolla white, sweetly scented; tube 2–2.5 cm. long.
A small shrub. It lies along the ground. It can be a climber. It has underground stems or rhizomes. It can be 6 m high. The leaves are simple and hairy. They are dull olive green. The flowers are white and have a sweet scent. They are at the ends of the side twigs. The fruit are green but ripen to purple or black.
Bushy or straggling shrub, sometimes climber or scrambler. Twigs tomentulose. Leaves unifoliolate, without acarodomatia, petioles articulate in lower half. Pedicels short and thick, about 5-7 mm long, densely pubescent. Calyx lobes up to 13, subulate, longer than calyx tube. Flowers white.
Leaves pilose, not darkening on drying; lamina 0·9–6 x 0·6–2 cm., very variable in shape, elliptic–ovate, elliptic–oblong or narrowly lanceolate to suborbicular, the apex tapering, rounded or occasionally emarginate, with minute thickened point, the base acute or obtuse.
Stamens inserted near top of corolla tube; filaments short; anthers 2–5–4–5 mm. long, reaching to within 1/2–2/5 anther lengths of base of corolla lobes.
Venation visible on both surfaces, main nerves raised below; lateral nerves several, the basal ones joining with others before reaching leaf apex.
Young shoots, petioles and inflorescences crispate–pilose with white or yellowish silvery hairs, bark of older twigs grey or brownish, smooth.
Corolla pure white; tube 16–33 mm. long; lobes 9–13, 12–22 mm. long, oblong or narrowly elliptic, the apex cuspidate or shortly acuminate.
Flowers terminal on short branches/solitary or in 3 (5)–flowered, cymes, sweetly scented; pedicels 3–10 mm. long.
Style either exserted from or 1/5–2/5 as long as corolla tube, with bifid stigma of variable form.
Suffrutex or low shrub 0·5–1·5 m. tall, rhizomatous, with much–branched sprawling stems.
Calyx crispate–pilose; tube 2–3 mm. long; lobes 7–15, 2·5–9 mm. long, filiform.
Petioles 5–13 mm. long, articulated in the middle or towards the base.
Fruits 1–2–lobed, lobes 1–1–5 cm. long when dry, ellipsoid.
Acarodomatia absent.
