Petiole light greyis green and suffused bronze, distally broadly, proximally narrowly winged, sparsely arachnoid; plant base with pale brownish hairs, without tunic. Leaves light greyish green, with mid-vein suffused bronze, oblanceolate in outline, 6–11 × 1,7–2.5 (–3) cm, sparsely arachnoid (mainly on mid-vein), pinnatilobed to pinnatipartite, with 3–4 pairs of ± triangular to almost falcate, strongly recurved, acute lateral segments with distal margin straight to sigmoid, entire (in distal segments) or with several thin teeth (proximal segments), proximal margin ± straight, entire; interlobes broad (8–15 × 6–10 mm); terminal lobe usually elongated-triangular, to ca. 4 cm long, usually subobtuse, entire or with 1–2 shallow incisions, basal lobules triangular, recurved. Scapes brownish pink, arachnoid, ± equalling leaves. Capitulum yellow, ca. 2.5 cm wide. Involucre greyish green, pruinose, 8–10 mm wide and ± rounded at base. Outer phyllaries usually 10–14, ± not imbricate, lanceolate to broadly lanceolate, usually 6–8 × 1.9–2.7 mm, loosely appressed to erect, often with recurved apex, most often with a white border to 0.3 mm wide and a broad greenish white and pruinose border, with a gradual transition into the relatively narrow (0.5–1 mm) blackish pruinose middle strip, margins ± glabrous, apex ± flat; inner phyllaries pale greyish green, to 14–15 mm long, ± flat at apex. Outer ligules ± flat, striped grey-purple outside, inner ligule teeth ± greyish. Anthers polliniferous, pollen grains ± irregular in size. Stigma grey-yellow, with dark pubescence outside. Achenes light ochraceous-fulvous, 4.6–5.0 × 1.3–1.5 mm, body thick, covered with robust squamules and spinules in upper 1/3, otherwise with lower thick spinules or tuberculate, abruptly narrowing into a thick subconical cone 1.0–1.1 × 0.4–0.5 mm (thicker at base, narrowing distally); beak ± thin, 7–7.5 mm, pappus yellowish white, 6–7 mm long.
