|discussion=<p>Plants perennial, monoecious and dioecious (developmentally, seasonally), trailing or climbing; stems perennial proximally, annual distally, woody, glabrous [hispid-hirsute or hispidulous]; roots tuberous; tendrils unbranched. Leaves: petiolar region an extension of blade midportion; blade ovate to orbiculate, deeply 3-lobed, lobes 1–2-lobed, ultimate segments narrow, margins entire, surfaces eglandular at base. Inflorescences: staminate flowers 2–19 in axillary, subsessile racemes; pistillate flowers solitary, from same axils as staminate; bracts absent. Flowers: hypanthium narrowly tubular-funnelform; sepals 5, deltate to triangular; petals 5, distinct, pale yellow to greenish yellow, narrowly triangular to linear-lanceolate, valvate in bud, 4–6 mm, apex entire, glabrous, corolla salverform. Staminate flowers: stamens 3; filaments inserted at hypanthium rim, distinct, nearly vestigial; thecae distinct, oblong, connective narrow, each with glabrous, narrow, exserted, terminal appendage nearly as long as corolla; pistillodes absent. Pistillate flowers: ovary 3-locular, ellipsoid; ovules ca. 2–6 per locule; style 1, narrowly columnar; stigmas 3, coiled; staminodes 3. Fruits berrylike, red or yellow, globose, 0.8–1 cm, smooth, glabrous, irregularly dehiscent. Seeds 8–20, obovoid to ovoid, compressed, arillate, margins obscure, surface tuberculate-rugose.</p><!--

Vines fetid; branches to 3 m, harshly strigose; tendrils usually branched from 1–5 cm beyond base. Leaves: petiole 3–7 cm; blade 8–15 cm wide, surfaces moderately to densely white-sericeous abaxially, glabrous adaxially. Inflorescences: staminate flowers in long-pedunculate racemes; pistillate flowers in loose fascicles; peduncle erect, 1–2 cm in flower, 6–9 cm in fruit. Flowers: hypanthium 10–18 mm; sepals erect, not recurving. Pepos 6–10 cm. Seeds light brown, 9–12 mm. 2n = 28.
