few to several from base, ascending or prostrate, (arising laterally, also from within basal leaves, usually unbranched, rarely branched), 0.5–3(–6) dm.

few to several from base, erect or outer ones decumbent, 0.5–4 dm.

blade narrowly oblanceolate or broadly elliptic, 1–7(–12) cm, margins entire or shallowly toothed, sometimes repand, (inner blades usually flattened in age, surfaces often gray-green, scabrous).

(long-petiolate);

blade elliptic to obovate or rhombic, 2–6(–9) cm, margins entire.

(usually secund);

blade spatulate or obovate, 1–2.5(–4.5) cm, margins entire or shallowly toothed, (flat or involute).

(sessile or shortly petiolate);

blade oblanceolate to spatulate, 1–3 cm, (proximal broader), margins entire.

somewhat crowded (to moderately elongated in fruit, exceeding basal leaves).

dense, (relatively short).

sepals broadly elliptic or oblong, 4–7.5(–9) mm, (median pair thickened apically, cucullate);

petals cuneate or obovate, 7–10(–16) mm, (tapering gradually to broad claw).
