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

simple from base, erect, (usually unbranched), to 4.5 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 suborbicular to elliptic, 2–9.5(–11.5) cm, margins entire, sinuate, coarsely dentate, or almost lyrate-pinnatifid.

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

similar to basal, blade narrowly linear or, sometimes, orbicular.

moderately dense (or elongated).

loose (lax).

sepals linear-oblong, 6–8 mm;
