simple from base, erect, (usually unbranched), to 4.5 dm.

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

blade suborbicular to elliptic, 2–9.5(–11.5) cm, margins entire, sinuate, coarsely dentate, or almost lyrate-pinnatifid.

(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).

similar to basal, blade narrowly linear or, sometimes, orbicular.

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

loose (lax).

congested, (elongated in fruit, greatly exceeding leaves).

sepals elliptic or ovate, (2–)3.5–7.5 mm, (cucullate);
