A scandent shrub or a woody liana 1–6 m long. Stem and branches glabrous; bark rough, light grey or brown. Leaves shortly petiolate; lamina ovate to elliptic, or somewhat cordate, margin entire, obtuse or shortly acuminate, 20–110 mm long, 15–75 mm wide, coriaceous or subcoriaceous, adaxial surface semiglossy green, abaxial surface dull pale green, glabrous; petiole slender, puberulous, 2–10 mm long. Inflorescence thyrsoid, 30–110 mm long, 40–120 mm wide. Flowers with sweet scent, pedicellate, bracteate, congested; pedicels hoary-pubescent, non-glandular, 1–3 mm long; bracts sessile, oblong to lanceolate, hoary-pubescent, c. 1 mm long. Calyx campanulate, shallowly 5-(6)-lobed, non-glandular, hoary-pubescent outside, glabrous inside, 3–4.5 mm long, 2–3 mm diameter near base of lobes; lobes short, rounded, shortly apiculate or sometimes nearly truncate, 0.5–1 mm long, c. 1 mm wide at base. Corolla white, infundibuliform, 5(6)-lobed, non-glandular, silky-pubescent outside, villous in throat; tube cylindrical below, enlarged near base of lobes, 5–7 mm long, 1.5–3 mm diameter near base of lobes; lobes elliptic to oblong, base obtuse, 2–3.5 mm long, 1.5–2.5 mm wide. Stamens exserted; filaments white, filiform, glabrous acropetally, villous at base, 6–9 mm long; anthers oblong to elliptic, 0.5–1 mm long. Ovary ellipsoid to obovoid, non-glandular, glabrous, sometimes with a few sparse hairs on top, shallowly 4-lobed, 1–1.5 mm long, c. 1 mm diameter; style white, filiform, glabrous, 9–12 mm long, stigma bifid. Fruit ellipsoid to obloid, rounded at top, much exserted above fruiting calyx, green when fresh, greyish brown when mature and dry, 4–10 mm long, 2–3.5 mm diameter, generally glabrous, dehiscent, splitting into 4 narrow mericarps, the lower seedless portion winged; fruiting calyx chartaceous, 3–4 mm diameter.
