Vines, twining or clambering. Stems green, apically tomentose grading to pilose or glabrate on older portions. Leaves not peltate. Leaf-blade generally ovate to hastate or oblong, base cordate, truncate, or rounded, margins entire, apex mucronate; surfaces soft-pubescent or glabrous. Inflorescences axillary or terminal, racemes or racemose-panicles; bracts minute (bracteoles). Flowers 3-ranked; sepals 6-9, ovate to elliptic or obovate, outer sepals glabrous or pilose to sparsely pilose abaxially, inner sepals glabrous; petals 6, free. Staminate flowers: petals to 2 mm, auriculate lobes at base inflexed over 6 stamens; filaments distinct; anthers 4-locular; pistillodes 36 or absent, glandular. Pistillate flowers: perianth similar to staminate; staminodes 6, poorly developed; pistils 6; ovary slightly asymmetrically pouched, glabrous; stigma entire.
