several from base, decumbent, (unbranched, leafy for the genus), ca. 1 dm.

simple from base, decumbent, (occasionally few-branched), 0.5–1.5(–2) 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).

blade elliptic to broadly obovate, triangular, rhombic, or round, 1.5–3(–4) cm, margins often sinuate or shallowly lobed.

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

(sessile or shortly petiolate);

blade elliptic to oblanceolate to obovate, 0.5–1.5 cm, (base narrowed to petiole), margins entire.
