Evergreen woody climber or scandent shrub, up to 20 m. Twigs glabrous; flowering twigs up to 5 mm diam., glabrous or sparsely pubescent. Buds ovoid, up to 2.5 mm, acute; scales glabrous to pubescent, (sub)ciliolate. Leaves oblong to sublanceolate, 5-14 (-18)by2-6(-8)cm, index (2-)2.5-3.5(-4), above and beneath glabrous or with very few hairs on midrib, pergamentaceous; base acute to rounded, apex acute, acuminate; nerves (5-)6-8(-9) pairs, patent, straight to curved; petiole up to 2 cm, glabrous to sparsely pubescent. Cymes either arranged in an axillary, up to 12 cm long, glabrous to sparsely pubescent, racemose to thyrsoid inflorescence, subtended by bracts, or solitary, axillary, often subtended by small leaves, up to 3.5 cm, 1-4-flowered, glabrous to sparsely pubescent; bracts oblong to lanceolate, up to 3.5 mm, subglabrous to somewhat pubescent, (sub)ciliolate; bracteoles as bracts but smaller, or minute, or sepal-like and then often situated near calyx; pedicels up to c. 1 cm. Flowers green to yellow or white. Sepals sometimes 6 (see bracteoles), ovate to broad-ovate, 0.75-1.25 by 0.7-1 mm, acute to obtuse, glabrous to somewhat pubescent, (sub)ciliolate. Petals oblong, sometimes somewhat oblong-ovate, 2.5-4(-4.5) by (0.75-) 1 —1.3(—1.5) mm, (narrow-)obtuse, sometimes sub-ciliolate, nerves up to 5, sometimes dark-coloured and then conspicuous. Stamens (l-)1.25-1.75(-2) mm; filament flattened, (0.75-)l-1.5(-1.75) by 0.25-0.5 mm; anther globular to ellipsoid, 0.2-0.3 mm, inflexed. Disk crown-shaped; lobes often short or irregular; ribs sometimes faint or absent. Pistil 1.3-1.7 mm; style conical, 0.6-1 mm, much shorter than the adjacent side(s) of the drupelet(s); ovary globular to subreniform, 0.5-0.7 by 0.5-0.8 mm, glabrous. Drupelets ± globular, sometimes somewhat obovoid, compressed, 7.5-11 by 8—10(—11) mm, white to red or dark-blue when fresh, without persistent petals and stamens, reticulate pattern fine to rather coarse, sometimes indistinct, limited to the margin or not. Embryo with somewhat undulated or faintly folded cotyledons.
