simple from base, loosely spreading, usually decumbent, (well exserted from basal leaves, often reddish purple), 0.8–2.4 dm.

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

blade (erect), spatulate to nearly rhombic, 2.5–5(–9) cm, (base gradually narrowed to petiole), margins entire, (flat).

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

blade spatulate, similar to basal, margins entire.

dense or slightly elongated.

loose, (elongated, exceeding basal leaves).
