blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid.

(petiole slender);

blade elliptic to rhombic, 1.5–4(–5) cm, (base gradually tapering to petiole), margins usually entire, rarely dentate.

(proximal often narrowed to short petiole, distal sessile);

blade broadly elliptic to obovate or rhombic, 0.5–3(–5) cm, margins entire.
