Lianas, climbing by tendrils or scrambling without support and producing adventitious roots, synoecious. Branches: bark adherent; pith white, continuous through nodes; tendrils 3–12-branched, with or without adhesive discs. Leaves usually palmately compound, sometimes simple. Inflorescences usually bisexual, leaf-opposed or terminal, paniclelike or corymblike cymes, sometimes compound. Flowers bisexual; calyx cup-shaped, shallowly 5-lobed; petals 5, distinct; nectary adnate to base of ovary, annular, entire, or absent; stamens 5; style conic, short. Berries dark blue or black. Seeds 2–4 per fruit. x = 10. Lianas, woody, hermaphroditic. Tendrils racemosely 4-12-branched, young apex expanded or curving, later turning into adhesive disks or suckers. Leaves simple, 3-foliolate, or palmately 5(-7)-foliolate. Inflorescence a panicle or a loose corymbose polychasium, pseudoterminal. Flowers 5-merous. Calyx cupular, glabrous, 5-dentate. Petals free. Stamens 5. Disk inconspicuous, rarely with 5 nectaries. Style conspicuous. Berry 1-4-seeded. Seeds obovoid, chalazal knot rounded at middle; ventral raphe raised; 2 lateral ventral holes furrowed upward from base to apex; endosperm cross-section M-shaped. 2n = 40.
