Perennials, 5–35 cm (taproots slender, caudices branched). Stems 1–4, erect, slender to stout, simple or sparsely branched, glabrate to tomentose and bristly-setose. Leaves basal and cauline; petiolate; basal blades lanceolate, 7–25 × 2–4 cm, margins deeply pinnately lobed (lobes lanceolate, dentate, teeth mucronate), apices acuminate, faces tomentulose (at least when young). Heads 1–9, borne singly or 2–9 in cymiform arrays. Calyculi of 8–10, lanceolate, tomentose and often setose bractlets 2–4 mm. Involucres cylindric, 11–21 × 5–10 mm. Phyllaries 8–18, (medially green) lanceolate, 10–16 mm, (bases keeled, margins yellowish, often scarious), apices acute, abaxial faces often densely, blackish or whitish tomentose or setose, sometimes glabrous, adaxial with fine (shiny) hairs. Florets 10–60; corollas yellow, 13–22 mm. Cypselae blackish or greenish, reddish, reddish brown, or yellowish, subcylindric to fusiform, 7–12 mm, apices tapered or beaked (beaks 1–3 mm), ribs 10 (strong to weak); pappi dusky white, 5–13 mm. 2n = 22, 33, 44, 55, 66, 88.
Distribution
