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

simple from base, prostrate, (arising lateral to rosette), 0.1–0.5 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 suborbicular, (1–)2.5(–3) cm, (base abruptly narrowed to petiole), margins entire, (flat), (surfaces densely silvery pubescent, trichomes in multiple layers, appressed).

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

(2–4);

blade oblanceolate, ca. 1 cm, (base cuneate), margins entire, (apex acute).

congested, (elongated moderately in fruit).

condensed.

sepals linear, 5–7 mm;
