several from base, erect or outer decumbent, (often several-branched, branches slender and flexuous), to 8 dm.

blade narrowly oblanceolate or broadly elliptic, 1–7(–12) cm, margins entire or shallowly toothed, sometimes repand, (inner blades usually flattened in age, surfaces often gray-green, scabrous).

blade pinnatisect to repand, 3–9(–14) cm, margins entire.

(usually secund);

blade spatulate or obovate, 1–2.5(–4.5) cm, margins entire or shallowly toothed, (flat or involute).

(sometimes secund, proximal usually petiolate, distal sessile);

blade elliptic, 1–6 cm, (distal with cuneate base), margins entire or deeply dentate.

somewhat crowded (to moderately elongated in fruit, exceeding basal leaves).

dense.
