Stem very short to high-climbing, generally twisting and twining
Leaf generally > 1 cm, linear to reniform, often sagittate to hastate, rarely deeply divided
Inflorescence: peduncle generally 1-flowered; bractlets small and remote from calyx to large and concealing calyx, sometimes lobed
Flower generally showy; corolla glabrous, white or yellow to pink or purple; ovary chamber 1 (septa generally incomplete), stigma lobes 2, generally swollen, cylindric or oblong, ± flattened
Fruit ± spheric, ± inflated
