several from base, decumbent to ascending (arising laterally, unbranched, stout), (0.2–)0.5–1.7 dm.

simple to several from base, erect, often outer decumbent, (unbranched or branched distally), 1–7 dm.

(petiole somewhat winged);

blades orbicular to obovate, 2–6 cm (width 1–2.5 cm, thick), margins usually repand, rarely entire, (adaxial surface scurfy).

blade oblanceolate to elliptic, 1.5–8(–11.5) cm, margins lyrate-pinnatifid to dentate or repand, (abaxial surface densely pubescent, adaxial sparsely pubescent).

blade oblanceolate to broadly spatulate, 1–2 cm (width 3–5 mm), margins entire, (apex obtuse to subacute).

(proximal petiolate, distal sessile);

blade oblanceolate to oblong, 1–7 cm, margins dentate to repand.

moderately dense (or elongated).

loose, (elongated).

sepals linear-oblong, 6–8 mm;
