several from base, erect or laterally decumbent, (usually unbranched), (0.3–)0.5–2.5(–4) dm.

few to several from base, ascending (in flower) to nearly prostrate (in fruit), (unbranched), 1–2.5 dm.

blade linear to somewhat elliptic, 1–4(–8) cm, margins entire or coarsely dentate.

(petiole 1–3.5 cm);

blade ovate to rhombic or rotund, 2–7 cm, (base narrowed abruptly to petiole), margins usually entire, occasionally shallowly repand, (flat).

(shortly petiolate);

blade usually linear to narrowly oblanceolate, rarely elliptic to rhombic, 0.5–2.5 cm, (base narrowing to petiole), margins entire or remotely dentate (sometimes involute).

blade elliptic or narrowly so, (0.7–)1–2.5 cm, (base narrowed gradually to petiole), margins entire.

loose to somewhat dense.

dense, (elongated in fruit).

sepals elliptic to oblong, 5–8 mm, (lateral pair not saccate, median pair often thickened apically, ± cucullate);

petals (usually orange or orange-yellow at junction of blade and claw, sometimes also with orange guidelines), obdeltate to obovate, 8–12 mm, (claw relatively short).
