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

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

(strongly rosulate);

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

blade oblanceolate, 1–1.5 cm (width 2–4 mm), margins entire, (apex 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, (elongated moderately in fruit).

loose to somewhat dense.

sepals linear, 5–7 mm;

petals spatulate, 8–10 mm, (apex often somewhat truncate).
