Deciduous woody climbers, up to 30 m long; stems glabrous, ca 5 cm thick, finely striate when young. Leaves peltate or not, broadly ovate to suborbicular, rounded to cordate at base, acuminate to rounded at apex, slightly crenate along margins, 6 - 11 cm across, chartaceous, glaucous beneath with fine reticulations; petioles 5 - 12 cm long, inserted up to 2.8 cm inside the lamina base. Inflorescences cauliflorous, up to 50 cm long, ca 8 cm wide. Male flowers pale yellow; pedicels 2 - 4 cm long; sepals 6, free; outer 3 elliptic, ca 2.5 cm long; inner ones 3, broadly elliptic, ca 2.5 mm long; petals 6, ovate-rhombic, auriculate at base, acute or emarginate at apex, ca 1 mm long, yellowish; stamens 6, free, ca 2 mm long; anthers dehiscing by transverse slits. Female flowers: sepals 6, in 2 whorls of 3 each; petals 6; staminodes 6, filamentose; carpels 3, ca 2 mm long. Drupes obovoid, ca 2.5 x 1.5 cm, yellow to orange; style-scar basal; endocarp elongate, narrowly obovate, 15 - 20 x 8 - 12 mm, transversely ridged, dorsally ornamented with transverse and longitudinal ridges.
