Leaves opposite to subopposite or alternate (on climbing shoots), petiolate; lamina dark green, paler below, glossy or more rarely rather dull on both surfaces, (3·3)4·4–10·8(15) × (1·2)2·1–4·5 cm., oblong or elliptic-oblong to obovate, acuminate at the apex with acumen long to short, obtuse or retuse, with margin shallowly rounded-denticulate, rarely subentire, cuneate to rounded at the base, chartaceous to softly coriaceous, with (6)7–10 lateral nerves and ± densely reticulate venation varying in prominence; petiole (2)3–4(6) mm. long, with margins markedly undulating; stipules small, asymmetric, ± ciliate-denticulate, caducous.
A shrub. The branches can be climbing. It grows to 5-8 m tall. The stems are angular. The leaves are opposite or alternate on climbing branches. The leaves are green but more pale underneath. They are 5-11 cm long by 2-5 cm wide. They are oval and taper at the tip. There are 1-5 flowers in a group in the axils of leaves. The fruit are orange and are 3 lobed but become round with age. They are 2-3 cm across. There are 1-3 seeds.
Shrub, often with climbing branches, or liane, (1)2–7(15) m. high, sometimes forming thickets, without latex, glabrous; stems with paired raised lines or quadrangular, olive-green to purplish and rugulose-tuberculate at first, becoming subterete, purplish-grey and smooth or remaining rugulose.
Flowers 1–5, axillary, in sessile or very shortly pedunculate fascicles, bisexual, 4–7(9) mm. in diam.; buds 2–3 mm. long, ovoid to ovoid-cylindric; pedicels 3–5(7) mm. long, smooth or slightly rugulose, articulated at the base.
Fruit orange, ovoid-3-gonous and acute when young, becoming 3-crested and eventually globose, 1·3–3 cm. in diam., smooth or with a few tubercles, 1–3-seeded.
Sepals green with pale subentire or irregularly denticulate margin, 0·4–1 mm. long, unequal, ovate to semicircular, rounded, free or shortly united.
Ovary ovoid, 3-gonous or 3-lobed, with style narrowly pyramidal; stigma entire; ovules (2)4–6 per loculus.
Disk brown, convex or convex-cylindric, without depressions, surrounding the ovary and wider than it.
Stamens 3, with filaments slender; anthers dehiscing by 2 oblique clefts confluent at the apex.
Petals greenish-yellow, 2–3(4) mm. long, oblong, rounded, entire.
