Small woody climber, entirely glabrous. Stems drying striate when young, later becoming minutely verruculose and bearing scattered raised lenticels. Leaves: petioles 2.5-9 cm; lamina triangular to broadly triangular, base broadly cordate to truncate with rounded, sometimes subhastate, basal lobes, apex acute, 6-10 by 4-9 cm, reticulation raised on both surfaces, papyraceous, glandular patches present on lower surface in axils of main nerves. Male inflorescences axillary, pseudo-racemose, (5—)7—15 cm long, the lower half without flowers, arising singly or 2-3 directly from the leaf-axils, or sometimes 2-3 arising from very short 1-1.6 cm long axillary shoot, flowers mostly in fascicles of 3-4. Male flowers on slender pedicels 4-5 mm; sepals white, outer 3 ± ovate, 1-1.5 mm long, inner 3 elliptic, 4 mm long; petals 6, obovate-cuneate, 1.5 mm long, fleshy, externally minutely papillose-glandular near base; stamens 6, narrowly clavate with filament broadened apically, 3.5-4.5 mm long. Female inflorescences pseudo-racemose, the flowers arising singly. Female flowers on pedicels 4-6 mm; sepals and petals similar to male but slightly smaller and petals thin; staminodes 6, oblong, 0.5 mm long; gynophore columnar, 1 mm long; carpels 3, gibbose-ellipsoidal, 1 mm long, stigma flat and expanded-with margin minutely lobed. Infructescences race-mose, 7-9 cm. Drupes red, radiating from columnar gynophore 4-5 mm long on peduncles 5-8 mm; pericarp drying thin; endocarp bony, ± elliptic in outline, shortly pointed at base, strongly keeled (in outline pointed) at apex, 7 by 4 mm, dorsally with a median ridge, surface coarsely and irregularly tuber culate and also minutely rugulose, ventrally with elliptic aperture to shallow ventral cavity,
