Small climber or creeper, root not known, 1-2 m long; leafy stem 1-1.5 mm diam., sparsely hairy, glabrescent; dioecious. Leaves: petiole 2-3.5 cm long; petiolules 0.5-1.5 cm long; blade membranous, (3-)5-7-foliolate, ovate or circular in outline, 3-6 cm diam., leaflets up to 5 by 2(-2.5) cm, middle leaflet largest, with 5-7 pairs of rather faint lateral veins, upper surface sparsely hairy mainly on veins, lower surface subglabrous, margin (shallowly) coarsely serrate. Male inflorescences many-flowered, paniculate, (2 or) 3 times branched, 10-15 by 5-10 cm, ultimately with up to 5 flowers in fascicles or short racemes up to 15 mm long; peduncle c. 3 cm long, finely pubescent; bracts minute, less than 1 mm long. Male flowers: pedicel 2-3 mm long, (sub)glabrous, articulation indistinct, at c. 1/3 from the apex; perianth glabrous, 4.5(-5) mm diam.; receptacle shallow, 0.6-0.9 mm wide; sepals ovate-narrowly elliptic, c. 1 by 0.5 mm; petals triangular-ovate, c. 2 by 1(-1.5) mm, entire, with narrowed apiculate apex; staminal column (0.3-)0.5 mm long, synandrium c. 0.5 mm diam., anthers subsessile, subglobose, c. 0.2 mm diameter. Female inflorescences as in male, paniculate, rather many-flowered, 1(-3) times branched, 5-10 cm long; peduncle 1.5-3 cm long, (sparsely) hairy. Female flowers: pedicel 3-4 mm long, articulation not seen; ovary (hemi-)globose, c. 1.5 mm diam., (sparsely) hairy or glabrous; perianth c. 4 mm diam.; styles 5, each c. 1 mm long. Fruit few or up to 20 per infructescence, shiny, ripening green or dark purple, globose, 0.6-1(-1.2) cm diam., with 5 style-remnants and 5 (not opening) valve-sutures, glabrous; fruiting pedicel c. 0.5 cm long. Seeds 3 or 4 per berry, pale brown, rounded-triangular, c. 4 by 3.5 by 2 mm, with ± flattish apex, coarsely sparsely warted or irregularly ridged, margin narrow.
