Characteristics

Perennial herb 30–50 cm high, with most leaves in a rosette; flowering stem(s) one or several, erect or weak, sometimes rather woody, (sparsely) branched distally, ± hollow, with milky latex, striate, glabrous to (sparsely) glandular-setose, near the capitulum with some minute white pubescence, with white latex; root large, semi-woody, with latex.. Leaves appressed to the ground or erect, dull to bright green, sessile, narrowly obovate or oblanceolate, 5–14 cm long, 0.7–2.5 cm wide, base attenuate, margins dentate to coarsely recurved-dentate, less often denticulate or pinnately lobed, apex acute or rounded and mucronate, glabrous or sparsely glandular-setose beneath, sometimes the indument restricted to midrib and veins, occasionally densely setose when young; cauline leaves absent or smaller than radical ones; midrib pallid.. Capitula erect, solitary or few together in lax corymbs; stalks of individual capitula sparsely pilose or glandular-setose, distally also short-pubescent; involucre 10–15 mm long; phyllaries pale to dark green, lanceolate, 4–12 mm, obtuse or acute, with scattered to dense dark or pale setae and usually short-pubescent at least proximally, sometimes glandular, usually only on the midrib, distally glabrous or setose, the inner phyllaries with pale scarious margins and often keeled and spongy near the base.. Corolla yellow to orange-yellow, tube cylindric, 6.5–8 mm long, (sparsely) pilose, ligule 7–9 mm long, 1–1.5 mm wide (shortest in the inner florets).. Achenes brown to orange-red, cylindrical becoming fusiform, (2–3 mm at anthesis) 7–10 mm long, distinctly beaked, beak 1.5–4 mm long, finely ribbed, the ribs antrorsely muricate; pappus 4.5–9 mm long, barbellate.. Fig. 17/4–5.

Leaves mostly basal in a rosette, sessile; blade oblong to narrowly obovate, up to 144 x 25 mm, apex rounded to acute mucronate, narrowed to base, margins remotely denticulate, irregularly and coarsely toothed or runcinate-pinnatifid, glabrous to ± densely hispid or glandular-setose. Heads ligulate, solitary at ends of branches or few in lax corymbs. Involucral bracts in a few rows, up to 15 mm long at fruiting, glabrous or white-woolly, densely glandular-setose. Flowers: pale yellow; Sep.-Nov. Fruit with cypsela cylindrical becoming fusiform, ribbed, with long beak, brown to orange red, 7-10 mm long, including 1.5-4.0 mm long beak. Pappus of many barbellate bristles.
A perennial herb up to 50 cm tall, flowering stems scape-like, nearly nude, sparsely clothed in white-woolly hairs and frequently also with long setae, often gland-tipped. Leaves mostly radical from a thick woody rootstock, up to 20 x 3 cm, oblong to lanceolate, narrowed to the base, sparsely setose, margins remotely denticulate, irregularly and coarsely toothed or runcinate-pinnatifid. Heads solitary or few in a very open corymb. Involucral bracts: inner up to 15 mm long in the fruiting head, white-woolly and densely glandular-setose, outer similar but only 6-8 mm long. Flowers pale yellow. Achenes subterete, long-beaked, rough with minute, upward-pointing projections, bright orange-red at maturity.
Perennial herb, up to 500 mm high, with milky sap. Leaves mostly radical in a basal rosette, oblong to lanceolate, narrowed to base, margins remotely denticulate, irregularly and coarsely toothed or runcinate-pinnatifid. Capitula ligulate, solitary or few together in an open corymb, long pedunculate; involucre white-woolly and densely glandular, at least 10 mm long at flowering. Florets pale yellow, 5-toothed. Flowering time Oct.-Dec. Pappus of many barbellate bristles. Cypselae subterete, rough, with long beak.
Leaves numerous, mostly radical in a rosette, up to c. 10 x 1.5 cm., exceptionally to c. 15 x 3 cm., linear-oblanceolate to oblanceolate, rounded to acute mucronate at the apices and narrowly tapering below, sinuate denticulate to ± recurved-dentate, sometimes coarsely toothed, glabrous to ± densely hispid or glandular-setose; upper leaves, when present, usually bract-like and sessile.
Phyllaries few-seriate, glabrous or pubescent and ± densely glandular-setose outside, the setae sometimes black and up to c. 1.5 mm. long, the midribs swelling at the base; the outer phyllaries 2–6 x 0.5–1 mm., linear, loosely arranged and extending briefly onto the capitulum stalk; the inner phyllaries up to c. 13 mm. long becoming linear-lanceolate.
