usually densely spreading- to slightly ascending-hairy, usually glabrous in distal 1/2.

densely spreading- to very sparsely hairy at least in proximal 1/2.

stipules translucent, strongly wine red-tinged proximally, lobes pale green, sometimes suffused wine red;

petiole densely spreading- or slightly ascending-hairy (especially in distal 1/3);

blade usually reniform to orbiculate, 7–9-lobed, margins flat, sometimes slightly undulate, basal sinuses relatively wide or narrow, basal lobes not overlapping, middle lobes rounded, as long as to longer than their half-widths, to as long as wide and with straight sides;

incisions usually absent or relatively short;

teeth usually slightly connivent, almost symmetric to ± asymmetric, apex acute, abaxial surface with nerves hairy throughout, internerve regions uniformly or irregularly hairy, adaxial densely appressed-hairy throughout.
