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

several from base, erect to decumbent, (unbranched, fertile stems from among basal leaves), 1.2–1.8 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).

(erect, not rosulate);

blade broadly oblanceolate, 4–8 cm, margins entire or shallowly sinuate-dentate, (apex acute).

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

(proximal petiolate);

blade narrowly lanceolate, similar to basal in size, (distal with cuneate base), margins entire.
