Leaves mostly radical in a rosette, usually c. 10 x 2 cm. sometimes up to c. 36 x 6 cm., oblanceolate-spathulate, acute or rounded mucronate at the apex, narrowly cuneate below, ± coarsely recurved-dentate on the margins, less often denticulate or lobed, glabrous, or sparsely glandular-setose beneath, midribs usually ± densely setose; cauline leaves when present smaller and linear-lanceolate.
Phyllaries few-seriate, becoming swollen at the base, glabrous outside or puberulent, sometimes dark glandular-setulose on the midribs; the outer 2–6 x 0.5–1 mm. and subulate, extending briefly onto the capitulum stalk; the inner up to c. 12 x 1.5 mm. becoming linear-lanceolate.
Achenes brown ripening to a bright orange-red, 4.5–7 x 0.5–0.75 mm., subterete, tapering above but not drawn out into a beak, finely uniformly ribbed, ribs antrorsely muricate; pappus of numerous, barbellate setae, up to 6 mm. long.
Flowering stalks erect often solitary, branching above, markedly striate, usually glabrous, sometimes sparsely glandular-setulose becoming hispid.
Capitula erect, few to many in corymbose clusters on the branches; stalks 0.3–4 cm. long, ± densely pubescent.
An erect subscapose perennial herb, up to c. 90 cm. tall from a large semi-woody rootstock.
Corollas yellow, up to c. 15 mm. long; ligule c. 10 x 2.5 mm., strap-shaped.
Involucres obovoid in bud, ± cylindric later.
