Climbing shrubs. Stems up to 10 m long, hairy, prickles few to many, 1-2 mm long, reddish. Leaves ovate, 7-15 by 4.5-9 cm, not or shallowly lobed, base subtruncate to cordate, margin grossly serrate, apex acute to subacuminate, sometimes obtuse, rather stiffly herbaceous, nervation pedate with 6-10 pairs of nerves, venation widely transverse, upper surface only hairy on main nerves, lower surface with scattered semi-appressed to patent hairs on nerves and veins, two-coloured. Petiole 1-4 cm long. Stipules rather persistent, 5-9 by 3-5 mm, pinnatisect to-partite with 3-5 pairs of 16bes, those 2-5 by 0.2-0.5 mm. Inflorescence an overhanging or pendant compound raceme, 15-35 cm long, with up to 12(—15) laterals of up to 9 cm, the laterals bearing up to 7 dichasia or cymes, each with up to 5 flowers. Bracts stipule-like to dentate, up to 6 mm long. Pedicels 6-10 mm long, densely woolly as are the other axes in the inflorescence. Flowers functionally unisexual, plants ?dioecious, flower buds broadly ovoid. Hypanthium cup-shaped, 4-5 mm across, densely woolly outside and also with appressed, straight hairs. Sepals (broadly) ovate, 3.5-5 by 3-5 mm, apiculate just under the obtuse apex outside, margins entire, indumentum outside as hypanthium. Petals obovate, 7-9 by 5-6 mm, apex rounded or emarginate, white. Stamens 70-140, glabrous, filaments up to 3 mm, anthers 1.5-2 mm long, staminodes in female flowers 60-100, up to 1.5 mm long, with minute anther rudiment. Pistils 30-100, ovaries densely long-hairy on the backside or glabrous, on slightly elevated, long-hairy torus, styles 1-3 mm long, pistillodes in supposedly male flowers as pistils but smaller. Collective fruits globose, up to 1 cm, compact, sepals spreading under ripe fruits. Fruits up to 3 mm long when dry, exocarp light red (to blackish?), still hairy to glabrous, mesocarp rather thick fleshy or juicy, endocarp with broad dorsal side.
