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

several from base, erect (and stout) or outer ones decumbent, (unbranched or branched, stiff and densely foliate, sterile leaf-bearing branches sometimes present), to 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 obovate or elliptic, to ca. 3 cm, margins sinuate or shallowly dentate.

(proximal usually shortly petiolate, distal sessile);

blade obovate to broadly elliptic, 1–3 cm, margins sinuate or shallowly toothed.

congested, (elongated moderately in fruit).

dense, compact, (elongated in fruit).

sepals linear, 5–7 mm;

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