simple from base, erect, (unbranched, sparsely leaved), to 7 dm.

several from base, prostrate to decumbent, 0.3–1 dm.

blade elliptic or obovate to oblong, 4–15 cm, margins entire, dentate, or lyrate-pinnatifid.

(rosulate; petiole winged);

blade orbicular to broadly obovate, 1.5–3 cm, margins entire or with broad, obscure toothlike angles each side at apex, (apex obtuse, surfaces densely pubescent, trichomes appressed).

(proximal often narrowed to short petiole, distal sessile);

blade broadly elliptic to obovate or rhombic, 0.5–3(–5) cm, margins entire.

blade broadly spatulate to linear-oblanceolate, 1–1.5 cm, margins entire.

dense or slightly elongated.

condensed, (subumbellate to slightly more elongated, few-flowered).

sepals elliptic to ovate, 3.5–6(–7) mm, (median pair usually thickened apically, cucullate);

petals (white, often purple-veined, fading purplish), suborbicular to obovate, obdeltate, or cuneate, 4.5–10(–12) mm, (often narrowed to broad claw, apex emarginate, less frequently claw undifferentiated from blade).
