Herbs usually 20–40 cm tall, perennial, sparsely rosulate. Rootstock cylindric. Caudex with entire hardened adaxially abundantly reddish brown lanate leaf sheath residues. Stems solitary or few, ± erect, sparsely branched apically, ± pubescent or rarely glabrous, densely leafy. Rosette leaves linear-lanceolate to linear, to 20 × 0.3–0.8 cm, rather rigid, apex filiform acuminate. Stem leaves many, similar to rosette leaves, sparsely pubescent or glabrous. Synflorescence corymbiform, usually with 2–4 capitula. Involucre cylindric, to 2.5 × 1–1.5 cm. Phyllaries abaxially arachnoid hairy; outermost phyllaries lanceolate, apex acuminate and bent. Florets yellow, ca. 1.5 × as long as involucre. Achene cylindric, usually 7–8 mm, densely villous. Pappus pale brownish, 2–2.5 cm. Fl. and fr. May–Aug. 2n = 12.

Perennial. Root vertical, cylindrical; root collar sometimes covered with indurescent sheaths of basal leaves, densely velutinous from long rusty hairs. Stems 20-55 cm high, few, less often solitary, slightly flexuous, weakly sulcate, pubescent (often floccose in leaf axils), less often glabrous, densely leafy throughout, usually branched, less often simple. Leaves linear-lanceolate or linear, 6-25 cm long and 2-6(10) mm wide, apex attenuate into subulate bent cusps, hard, with many veins (rather distinct). Capitula solitary or two to four, terminal. Involucre more or less lanate-velutinous (sometimes pubescence forms white collar around involucre - var. pilosior O. Ktze.); involucral bracts lanceolate, long-acuminate; outer bracts reduced, with bent cusp. Ligulate florets yellow, one and one-half times as long as involucre. Achenes lanate; pappus dirty yellow or rusty, its bristles plumose from base, two to two and one-half times as long as achenes.
