several from base, usually somewhat decumbent, (unbranched), (0.4–)0.5–2 dm.

simple from base, decumbent to nearly prostrate, 0.5–1.3 dm.

(petiole slender, often narrowly winged);

blade obovate to orbicular or rhombic-orbicular, 2–9 cm, (base abruptly narrowed to petiole), margins usually entire, rarely with few scattered teeth, (apex rounded or obtuse, sometimes with apical mucro).

(strongly rosulate; shortly petiolate);

blade broadly obovate, 1.5–7.5 (width 7.5–26 mm, base gradually tapering to petiole), margins shallowly dentate, (apex obtuse).

blade spatulate to oblanceolate, 1–3 cm, margins entire, (apex usually obtuse).

blade oblanceolate to broadly obovate, 1–2.5 cm, margins entire.

loose, (elongated in fruit).

dense.

sepals linear-oblong, 4–7.5 mm;

petals spatulate, 6–11 mm.

sepals (pale yellow or yellow-green), narrowly lanceolate to narrowly deltate, 4–8 mm;
