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

(petiole slender);

blade obovate to orbicular, 3–6 cm (width 10–20 mm), margins entire or dentate.

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

blade spatulate, 1–2 cm (width 3–6 mm), margins entire, (apex often acute).

(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).

congested.

loose to somewhat dense.

sepals narrowly lanceolate, 5–8(–9) mm;

petals narrowly oblanceolate, 9–12 mm, (claw undifferentiated from blade).
