Vine stem diameters to 7 cm recorded. Vascular rays just visible to the naked eye. Dead bark +/- mustard-coloured when cut.
Leaf blades about 6.5-17 x 2-8 cm, petioles about 0.5-0.8 cm long, flat or grooved on the upper surface. Stipules not obvious but stipular scars quite easily seen. Tendrils in pairs, thick and heavy, resembling rams horns.
Flowers about 3.5-4 mm diam. Calyx lobes small, about 0.75-1 mm long. Corolla tube about 4 mm long, lobes about 2 mm long. Anthers about 1 mm long, filaments about 0.5 mm long. Ovary glabrous, about 1.5 mm long. Style + stigma about 3.5 mm long. Style clothed in hairs.
Fruits globose, about 18-25 x 15-25 mm, orange when ripe, perianth lobes persistent at the base. Seeds flat, 1-4 per fruit, each seed about 15-17 x 10-15 mm. Endosperm hard and oily. Embryo white, about 5 mm long. Cotyledons about 2 mm long, radicle about 3 mm long.
Cotyledons cordate, about 2.5-3 x 1.5-2.5 cm, petioles very short or absent. One or two cataphylls produced before the first pair of true leaves. First pair of true leaves narrowly ovate to narrowly elliptic, leaf blades three-veined, about 3.5-4 x 1-1.5 cm, apex apiculate, base obtuse. At the tenth leaf stage: leaf blade ovate, elliptic to lanceolate, apex acuminate, base cuneate to obtuse, midrib flush or slightly depressed on the upper surface. Stem and petioles shortly hairy.
