simple or several from base, prostrate to erect, 0.5–2(–3.5) dm.

several from base, decumbent, (unbranched, slender), 0.5–1 dm.

blade suborbicular or obovate to elliptic, (1–)2–5(–7) cm, margins entire, sinuate, or shallowly dentate.

(strongly rosulate);

blade usually oblanceolate or broader, sometimes triangular, 2–3.5 cm (width 5–10 mm), margins entire or with 1 or 2 broad teeth, (apex acute).

(often secund, proximal shortly petiolate, distal sessile);

blade linear to obovate or rhombic, 1–2.5(–4) cm, margins entire or shallowly dentate.

blade oblanceolate, 1–1.5 cm (width 2–4 mm), margins entire, (apex acute).

dense, compact, (usually elongated in fruit).

congested, (elongated moderately in fruit).

sepals elliptic, 5–8.5 mm, (lateral pair boat-shaped, saccate, median pair thickened apically, cucullate);

petals (yellow to orange, sometimes fading purplish), narrowly spatulate or obovate, (6–)7.5–12 mm, (claw undifferentiated from blade, or gradually narrowed to claw, slightly expanded basally).
