simple from base, decumbent to nearly prostrate, 0.5–1.3 dm.

blade pandurate or obovate, 3–6 cm, margins usually deeply and broadly incised, rarely subentire, (apex obtuse).

(strongly rosulate; shortly petiolate);

blade broadly obovate, 1.5–7.5 (width 7.5–26 mm, base gradually tapering to petiole), margins shallowly dentate, (apex obtuse).

blade oblanceolate to spatulate, similar to basal, (3–6 mm wide), margins entire, (apex often somewhat acute).
