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

several from base, erect (and stout) or outer ones decumbent, (unbranched or branched, stiff and densely foliate, sterile leaf-bearing branches sometimes present), to 4 dm.

(erect);

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

blade obovate or elliptic, to ca. 3 cm, margins sinuate or shallowly dentate.

blade linear, similar to basal.

(proximal usually shortly petiolate, distal sessile);

blade obovate to broadly elliptic, 1–3 cm, margins sinuate or shallowly toothed.

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