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

simple from base, erect or outer ones slightly decumbent toward base, (from below or in basal leaves, unbranched), (0.5–)0.8–1.6(–2) 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).

(erect, petiole long, slender);

blade spatulate to broadly oblanceolate, (3–)5–7(–12) cm, (base gradually tapering to petiole), margins entire, (apex rounded or obtuse).

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

blade oblanceolate, similar to basal, (base cuneate), margins entire.

congested, (elongated moderately in fruit).
