stipules linear to narrowly elliptic, 4 × 0.5–2 mm;

petiole 1–2(–3) cm;

blade broadly ovate to obovate, (3–)4–8 cm, usually as wide as long, base rounded to truncate or slightly cordate, 3- or 5-lobed, margins irregularly crenate to doubly serrate, apex obtuse to acute, abaxial surface paler, glabrous or more densely stellate-hairy, adaxial glabrous or sparsely stellate-hairy.
