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

simple from base, erect, (arising from a condensed rosette), to 1 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).

(ascending or erect);

blade elliptic to oblanceolate to obovate, (usually curled from middle to apex), (1.5–)5–7 cm (width 12–20 mm), margins entire.

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

(1–5);

blade oblanceolate, 1–2.5 cm, margins entire.

congested, (elongated moderately in fruit).

compact (or elongated in fruit, to 1 dm, barely exceeding leaves).

sepals linear, 5–7 mm;

ovules 4 per ovary;

style 5–7 mm.

didymous, irregular, highly inflated, 8–11(–18) × 10–15 mm, (papery, basal sinus shallower than the deep apical sinus; valves retaining seeds after dehiscence);
