Characteristics

Lianas, rarely sarmentose shrubs with long curled tendrils, branched at the very tip; latex present in all parts, often abundant; stipules absent. Leaves opposite; petiole often alternating with one or several pairs of bracts. Inflorescence terminal and/or axillary, sometimes tendril-like, a lax to dense cyme. Flowers 5-merous, fragrant. Sepals imbricate, free or shortly united at the base. Corolla variously coloured; tube cylindrical, slightly enlarged at the level of the anthers, thickened above the anthers; lobes broadly elliptic to narrowly linear, contorted, overlapping to the left. Stamens included, free from each other and from pistil head; filaments very short. Ovary glabrous or hairy; ovules numerous; style terete, stigma bifid, subtended by a clavuncula positioned at the level of the base of the anthers. Fruit a many-seeded indehiscent berry with or without a sclerified pericarp; pulp sweet and acid. Seeds many, endospermous.
