simple or few from base, ascending to erect, (0.5–)1–2(–3.5) dm.

(forming a strong rosette; long-petiolate);

blade obovate, 1.5–4(–8) cm, (base ± abruptly narrowing to petiole), margins usually repand or dentate, rarely entire, (apex usually angular, surfaces silvery).

(petiole tapering to blade);

blade rhombic to elliptic and irregularly angular, sometimes spatulate to oblanceolate, 1.5–7.5(–10) cm, margins entire.

blade oblanceolate, 1–2 cm (width 4–8 mm), margins entire or with occasional tooth, (apex acute).

(not or loosely overlapping, petiolate or distal sessile);
