Plants high climbing, sparsely branched. Branches: bark exfoliating in shreds; nodal diaphragms 0.3–1.1 mm thick; branchlets terete, sparsely arachnoid or glabrous, growing tips not enveloped by unfolding leaves; tendrils along length of branchlets, persistent, branched, tendrils (or inflorescences) at 3+ consecutive nodes, usually not at all nodes; nodes not red-banded. Leaves: stipules 2.5–6 mm; petiole 1/2 to ± equaling blade; blade cordate, 10–20 cm, usually 3-shouldered, apex acute to short acuminate, abaxial surface not glaucous, ± densely arachnoid when young, sparsely arachnoid when mature, visible through hairs, adaxial surface usually glabrous.
