several from base, (slender), erect or outer decumbent, (usually branched, branches filiform, bud clusters of growing plants drooping), to 2.5 dm.

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

blade orbicular to broadly spatulate, 1–2.4 cm, margins entire or sinuate.

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

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

similar to basal, blade spatulate to oblanceolate or (distal) linear, (base cuneate), margins entire or sinuate.
