Climber, rarely erect shrubs, usually evergreen, dioecious, usually with short thick rhizomes. Stem and branches usually prickly. Leaves alternate, rarely opposite, persistent; leaf blade lanceolate, oblong, ovate or suborbicular, 3-5(-7)-nerved, nerves convergent, veins reticulate; petiole usually narrowly winged proximally (stipules), with an abscission zone between winged portion and apex; tendrils absent or present in pairs, arising from winged part of petiole. Inflorescence borne in axil of leaf or scale-like bract, of 1(-3) umbels or a panicle, raceme or spike of umbels, peduncle sometimes with a scale-like prophyll at base. Flowers pedicellate, small, unisexual. Male Flowers: Perianth of 6 tepals in 2 whorls, usually free, incurved or recurved, greenish, yellow or bronze. Stamens 6, rarely 8 or more, inserted at base of tepals, free; anthers bithecous, oblong, with contiguous cells or separated by forking. Female Flowers: Perianth as in male flowers. Staminodes 3 or 6, filiform. Ovary 3-angled, 3-loculed, ovules 1-2 in each loculus pendulous; style 0 or short; stigmas 3, stout, recurved. Fruit a globose berry. Seeds 1-3.
