Roots conical or cylindrical, 15-30 × 1-1.4 cm, ± branched. Stems twining, more than 1 m; branches and branchlets short, no more than 5 cm, leafy, sterile or with terminal flowers, sparsely villous or eventually glabrescent. Leaves alternate or opposite; petiole 1-8 cm, villous or hirsute; blade abaxially gray-green, adaxially green, deltoid or broadly ovate, 3-10 × 4-10 cm, both surfaces sparsely puberulent or hirsute, base shallowly cordate, truncate, or rounded, margin coarsely dentate, apex acuminate or acute.
