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

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

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).

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

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

congested, (elongated moderately in fruit).

dense, compact, (usually elongated in fruit).

sepals linear, 5–7 mm;
