few to several from base, erect or outer decumbent, 0.5–2.5 dm.

simple from base, erect, (unbranched, sparsely leaved), to 7 dm.

blade suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate.

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