Small to medium-sized climbing or trailing tuberous-rooted perennial herbs. Leaves simple; blade broadly ovate-or reniform-cordate in outline, palmately lobed, sometimes rather finely dissected. Tendrils simple. Flowers small, dull-or greenish-yellow, monoecious. Male flowers in few-to many-flowered subcapitate to somewhat elongated usually fairly dense pedunculate racemes sometimes produced at the nodes on contracted ± leafless branches; receptacle-tube campanulate; lobes small; petals united at the base; stamens 5, all 1-thecous, in 2 pairs with 1 single, inserted in mouth of tube, or the paired stamens ± united, when completely so then the stamens appearing as 3, 2 double 2-thecous, 1 single 1-thecous, the double stamens then often ± bilobed; filaments short; thecae short, straight, lateral; disk basal, fused to base of tube. Female flowers solitary or fasciculate, subsessile, often coaxillary with ♂; ovary smooth, glabrous or hairy; ovules few to many, horizontal; perianth as in ♂; staminodes when present 5, subulate, inserted in mouth of tube; stigmas 2(–3)-lobed; disk basal, obscure, not distinct from base of tube. Fruit a small red ovoid or ellipsoid often apically beaked berry, the basal part green, stalk-like, and expanded into a cup from which the upper red portion separates in an operculate manner at maturity. Seeds small, asymmetrically pyriform or rarely subglobose. Fig. 24, p. 140.
