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

few to several from base, ± erect, (arising laterally, also from within basal leaves), 0.2–0.4 dm.

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

(erect);

blade linear-oblanceolate, 1.2–2.8 cm, (base gradually narrowed to petiole), margins entire.

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

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

blade linear, similar to basal.

dense or slightly elongated.

dense, (often subumbellate, not or barely exceeding basal leaves).

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