Leaves: petiole ochraceous–pubescent, mostly transversely rugose when dry, 1–5(6) mm. long; lamina shining or mat and medium to dark green above, paler and often with dark veins beneath, papyraceous, coriaceous, or subcoriaceous, thinner when growing in shade, also when fresh, very variable in shape and size, ovate, elliptic or narrowly ovate, 1–3·5 x as long as wide, broadest on the main axis and at the base of the branchlets, 1·8–7(10) x 1–4(5) cm., usually obtuse and apiculate, but often acute, sometimes obtusely acuminate or emarginate at the apex, rounded, cuneate, or sometimes subcordate at the base, glabrous or ochraceous–pubescent beneath on the costa and main secondary veins, especially at the base, and above on the costa near the base; one or two pairs of secondary veins from or from above the base curved along the margin; tertiary venation inconspicuous above, prominent beneath.
Corolla in the mature bud 2·5–3 x as long as the calyx, 2·2–5 mm. long, white or yellow, fading from white to yellow, subrotate, 4–4·5 mm. in diam., glabrous or minutely papillose–pubescent outside, inside on the base of the lobes densely pilose with dirty white hairs (sometimes complete lobes pilose); tube very short, shorter than the calyx, 0·4–0·6 mm. long; lobes ovate to triangular, 2·7–4·5 x as long as the tube, comparatively wider in 4–merous flowers, 1·2–1·7 x as long as wide, 1·5–2 x 1–1·4 mm., acute, spreading.
Inflorescence axillary and sometimes also terminal, solitary, lax, few–flowered, about 0·5–1 x as long as the leaves, sometimes transformed into rose–like galls. Lateral branches usually 3–flowered. Peduncle and branches slender, ochraceous–pubescent as the very short pedicels.
Sepals pale green, equal or sometimes unequal, connate at the base up to one–third of their length, broadly ovate, 0·7–1·2 x as long as wide, (0·5)0·8–1·2 x (0·5)0·7–1 mm., acute or obtuse at the apex, glabrous on both sides, ciliate, without colleters.
Stamens just exserted; filaments about as long as the anthers, inserted at the mouth of the corolla tube; anthers yellow, glabrous, ovate or suborbicular, 0·5–1 x 0·5–0·8 mm., deeply cordate at the base.
Fruit orange or red, immature glaucous, small, soft, ellipsoid or globose, 12 x 12–22 x 18 mm., 1–seeded, with smooth skin, slightly shining or mat, obliquely pedicellate. Wall thin, 1 mm. thick.
Seed shining when living, dark brown, smooth, approximately bean–shaped with an impressed hilum or ellipsoid, 8·5 x 6 x 5–15 X 11 x 9 mm., glabrous; testa very thin, easily rubbed off.
Branches not lenticellate, medium to dark brown when dry, usually hairy like the branchlets; branchlets ochraceous–pubescent, green, terete, not sulcate when dry.
Pistil glabrous, 1·2–1·6 mm. long; ovary globose or broadly ovoid, 0·8–1·2 x 0·6–0·9 mm.; style short or very short, 0·1–0·7 mm. long; stigma capitate.
Climbing shrub or liana, 3–30 m. high, climbing over shrubs and in trees, or small semiscandent tree, 5–12 m. high.
Bark smooth, thin, pale brown, not or slightly lenticellate, in section pale yellow; wood pale yellow.
Tendrils solitary, in the axils of small triangular bracts.
Flowers 4–5–merous, even in a single inflorescence.
Flowers in short puberulous axillary cymes
Bracts narrowly triangular or sepal–like.
In each cell 4–6 ovules.
Trunk 4–20 cm. in diam.
Solitary tendrils
A liane
