Woody vines, monoecious. Leaves papyraceous, ocasionally membraneous, (3.5-)5-10 µm thick; lamina ovate, occasionally elliptic, (7-)9-12(-15) by (3.5-)4.5-7(-8.5) cm, length:width ratio (1.5-)1.7-2.1(-2.5); primary vein slightly impressed to impressed above, prominent below; secondary veins (3-)4-5 pairs, arcuate; base obtuse to truncate (acute in younger leaves), often short-decurrent; apex acuminate; margin denticulate, occasionally entire, 0-11(-15) teeth; petiole (13-)16-25(-46) mm long, (0.6-)0.7-1.1 (-1.5) mm diameter. Flowers borne axillary to leaves on young growth, solitary; pedicel (24-)30-40(-65) mm long, (0.2-)0.3-0.6(-0.7) mm diameter. Perianth segments 8-10; outermost perianth part ovate, 1.5—1.9(—3.2) by (1.5-)2.0-3.0 mm, length: width ratio (0.6-)0.9-1.2; innermost perianth part orbiculate, elliptic, ovate or obovate, (2.4-)4.2-5.2 by (2.2-)2.8-3.3 mm, length: width ratio (l.l-)l.3-2.0; largest perianth part ovate, 7.0-8.2 by (4.6-)6.9-8.4(-10.0) mm, length: width ratio 0.8-1.2(-l.5); outermost perianth part highly reduced to 0.2-0.4 of length of largest; innermost perianth part reduced to (0.3-)0.6-0.7 of length of largest. Male flowers with 27-30 stamens, filaments fused at the base only, androecium c. 3.5 mm diameter; pollen hexacolpate. Female flowers with 20-45 free carpels, gynoecium 3.0-3.4 mm diameter; ovaries 1.3-1.8 by 0.6-0.7(-0.8) mm, length:width ratio 2.0-3.0; pseudo-style round-subulate, without pseudostigma. Fruit pedicel elongated, 40-67 mm long; torus 31-75 mm long; berries 10-20 (possibly more), 6.8-8.6 by 4.5-6.2 mm, length: width ratio (1.1-)1.5-1.8, berries borne on short stipes 1.3-2.3 mm long.
