several from base, usually decumbent to ascending, (arising laterally, unbranched, coarse), 1–2 dm.

simple from base, erect, (arising from a condensed rosette), to 1 dm.

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

(ascending or erect);

blade elliptic to oblanceolate to obovate, (usually curled from middle to apex), (1.5–)5–7 cm (width 12–20 mm), margins entire.

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

(1–5);

blade oblanceolate, 1–2.5 cm, margins entire.

congested, (elongated in fruit).

sepals oblong, 6–8 mm;

petals spatulate, to 10 mm.
