Characteristics

Erect herbs or scandent or clambering shrubs, unarmed. Leaves alternate, petioled, ovate to lanceolate, acute, entire. Flowers in axillary and terminal, simple or branched, frequently panicled racemes or spikes, solitary in the axil of a bract, subtended by 2 bracteoles. Tepals 5, rarely 4, oval-oblong, 1-nerved with scarious margins, glabrous. Stamens 5, rarely 4, filaments at the base united in a cup; free parts distant, filiform-subulate; no pseudo-staminodes; anthers 2-celled (4-locellate). Ovary sessile or shortly stalked; ovules few to many; funicles long; stigmas 2-3, rarely 4, linear or ± clavate. Fruit baccate, thin-walled, indehiscent, globose, broadly ellipsoid or obovoid, falling out of persistent perianth when ripe; seeds 0 to many, on long pale funicles, circular or reniform, shining black or brownish black, very finely verruculose or almost smooth.
