Leaves with a glabrous, 2–5 mm. long petiole; lamina mat or slightly shining and dark green above, dull or slightly shining and paler and often glaucous beneath, drying dark brown to pale greenish–brown, in the sun coriaceous, in the shade subcoriaceous, elliptic, obovate, or on the main axis (climbers) subcircular, (1)1–5–5·5 times as long as wide, 2–7(11) x 1–4(5) cm., acute, apiculate, or shortly acuminate at the apex, cuneate or less often rounded at the base, glabrous on both sides; one pair of secondary veins from or from above the base curved along the margin and often accompanied by a faint submarginal pair; costa impressed above; tertiary venation reticulate, often prominent on both sides.

Corolla in the mature bud (3·5)4·5–5·5 times as long as the calyx, (5·2)5·7–6·7 mm. long, slightly contracted somewhat beneath the throat, and tapering at the apex, white with often pale green tips at the lobes, outside glabrous or sometimes minutely papillose–pubescent, inside densely pilose to glabrous on the lobes and sometimes also in the tube; tube cylindrical or nearly so, (2)3–3·5 times as long as the calyx, (1·4)1·7–2 times as long as the lobes, (3)3·5–4·5 mm. long, at the throat 1–1–4(2) mm. wide; lobes oblong, 2·2–2·5 mm., acute, recurved.
Seed flattened, obliquely ellipsoid, 13 x 8 x 4 to 16 x 11 x 6 mm.,at one side with a deep pit at the other with a bulge surrounded by a shallow groove, seemingly papillose; false papillae simulated by curved hairs.
Sepals connate at the base, equal or subequal, subcircular, 1–2 times as long as wide, 1·2–1·4 x 1–1·2 mm., obtuse or subacute at the apex, glabrous on both sides, often very minutely ciliate, without colleters.
Fruit orange–yellow or yellowish, immature glaucous, small, soft, obovoid or ellipsoid, 1·5 x 1–2 x 1·5 cm., apiculate at the apex, often slightly obliquely pedicellate, 1–seeded, with a smooth skin. Wall thin.
Inflorescence axillary, solitary, more or less congested, usually few–flowered, much shorter than the leaves, 1–2 times branched. Peduncle, branches, and pedicels usually short, glabrous.
Pistil glabrous, (3·5)5–6 mm. long; ovary ovoid, 1–1·5(2) x 0·7–1(1·2) mm., 2–celled; style slender, (1·5)5–6 mm. long; stigma small, capitate or obscurely bilobed.
Stamens slightly exserted; filaments glabrous, usually short, inserted at the mouth of the corolla tube; anthers oblong, 0·7–1 x 0·3–0·7 mm., glabrous.
Small fire resistant savanna shrub, 10–50 cm. high, or climbing shrub or liana, 2–5 m. high climbing and about 10–20 m. long or more.
Bark dark brown, shallowly fissured, with large tuberculate lenticels; wood pale yellow.
Trunk in shrub very thin, about 0·5 cm. in diam., in liana up to 12 cm. in diam.
Branches usually quadrangular, glabrous, not or hardly sulcate when dry.
Tendrils in 1–3 pairs above each other.
Each cell with 5–9 ovules.
Flowers 4(–5)–merous.
