1, erect (fistulose), branched distally or from bases, tomentulose and/or hispid.

1–3, erect or ascending, scapiform, branched near middles, glabrous or hispid, sometimes stipitate-glandular distally.

basal and cauline; petiolate;

blades lanceolate to oblanceolate, often coarsely runcinate, 5–15 × 1–4 cm, margins entire, denticulate, or dentate to pinnately lobed (lobes remote, coarse, unequal), apices acute to acuminate, abaxial faces glabrous or tomentose, adaxial glabrous (proximal cauline sessile, bases auriculate, distal usually linear, entire).

mostly basal (rosettes); petiolate;

blades elliptic, lanceolate, linear, oblanceolate, obovate, or spatulate, 3–30 × 0.5–8 cm (bases attenuate) margins usually entire or weakly dentate, sometimes serrate, dentate, or pinnately lobed, apices rounded, faces glabrous or hispid to hispidulous (sometimes glaucous).
