stipules persistent, broadly lanceolate, 4–5 × 2–3 mm;

petiole 2–3(–4) times as long as blade;

blade suborbiculate-cordate or reniform, mostly shallowly 5–7-lobed or angled, 2–8(–10) × 2–8(–10) cm, base cordate (to nearly truncate), lobes deltate or rounded, margins evenly crenate, apex rounded to broadly acute, surfaces glabrous or hairy, especially at base, hairs simple and stellate.
