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

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

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

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.

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

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

(proximal petiolate, distal sessile);

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

dense, compact, (usually elongated in fruit).

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