Ampelocissus Planchon, nom. cons

Climbing shrubs; branches terete, angled or sometimes flattened, hairy or glabrous. Leaves simple to pedately or digitately 3-9-foliolate, petiolate, densely hairy to glabrous; leaflets petiolulate, the terminal the largest; stipules deltate, inconspicuous, caducous. Inflorescences leaf-opposed, pedunculate, cirrhiferous cymes, thyrses or paniculate spikes. Flowers bisexual. Calyx Cupular or saucer-shaped, entire or obscurely lobed. Petals 5, free, oblong to ovate-oblong. Stamens 5; filaments short. Disc angular, adnate to ovary, often 5-10-grooved. Ovary usually 10-grooved; style short or absent; stigma minute or discoid. Berries moderately pulpy, 1-4-seeded. Seeds obovate to elliptic-oblong or suborbicular in outline, adaxial surface flattened or angular; raphe linear, somewhat ridged with a parallel wide shallow groove on either side, abaxial surface usually convex; chalazal knot somewhat spatulate in the shallow depression; endosperm T-shaped in cross-section.

Chiefly in tropical Asia and Africa, extending to C. America, Australia and Papua New Guinea; ca 100 species, 10 in India.
