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

few to several from base, prostrate to decumbent or erect, 0.5–2(–4) dm.

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

blade suborbicular to narrowly or broadly oblanceolate to broadly elliptic or rhombic, (1.2–)2–6(–8) cm, (base usually abruptly narrowed to petiole), margins entire, sinuate, or lobed.

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

(proximal petiolate, distal sessile);

blade obovate or elliptic to spatulate, 0.5–2 cm, margins entire.

congested, (elongated in fruit).

(usually not secund), dense, (sometimes elongated in fruit).

sepals oblong, 6–8 mm;

petals spatulate, to 10 mm.

sepals lanceolate, 4–6(–7) mm;
