Leaves: petiole (1–)2–4(–7) cm; blade orbiculate-pentagonal to deeply 5-lobed, sinuses (1/3–)1/2–2/3 to base, 4–10 × (4–)6–12 cm, terminal lobe deltate-acuminate to oblong-oblanceolate or obtrullate, basal sinus narrow to broad, margins not dentate, sometimes with few shallow, serrate teeth, evenly sharply indurate-apiculate, barely scabrous, not ciliate, surfaces hirsute to hispid-hirsute; proximal pair of lateral veins divergent from edge of basal sinus. Inflorescences: staminate 10–16-flowered, peduncle plus floral axis 40–140 mm; pistillate 4–10-flowered, peduncle (0–)1–5(–20) mm. Flowers: staminate: corolla greenish white, 2–3 mm, stamens not exserted; pistillate: sepals not foliaceous, mostly triangular, 0.2–2 mm, corolla 1–2 mm (essentially without a tube), stigmas 3-lobed. Pepos ovoid, 5–8 mm, echinate and sparsely, finely villous, spinules retrorsely barbellate.
