"Plants medium-sized, relatively robust, usually 12–18 cm tall, fruiting scapes usually to 25 cm. Petiole purplish, 2–4 cm long, broadly winged; plant base without visible tunic, with sparse to subdense whitish hairs. Leaves variously erect-patent, greyish green and usually suffused bronze or brown-purple, slightly fleshy, sparsely arachnoid to subglabrous, with mid-vein usually wholly brown-purple, or at least proximally so, narrowly oblong-elliptical, 7–15 × 1.5–4 cm, pinnatipartite to pinnatisect, with (3) 4–5 pairs of relatively short, deltoid-triangular, slightly recurved with a spreading tip, acute to acuminate lateral segments usually 0.8–1.5 × 0.7–1.5 cm, distal margin subconcave, sigmoid or ± straight, entire or (in inner leaves) very sparsely filiform-dentate, proximal margin ± straight or subconcave or subconvex, entire or with a single little proximal tooth; interlobes usually short and broad, most often 2–10 × 3–11 mm, sometimes with a narrow brown-purple margin, usually entire; terminal segment relatively small, broadly triangular to ± trilobed, with a mucronate-lingulate apex, usually 0.8–2 × 0.9–1.8 cm, with distal margin usually sigmoid, entire, basal lobules subrecurved to patent, acute-acuminate, proximal margin ± straight or slightly concave, entire. Scapes purplish basally and below capitulum, arachnoid, equalling leaves or longer. Capitulum yellow, 3–4 cm wide, ± flat. Involucre slightly pruinose, usually 9–11 mm wide and broadly rounded at base. Outer phyllaries paler than the inner ones, usually 11–14, usually arcuate-recurved to erect-recurved, subimbricate, ovate to lanceolate, 7–9 × 2.5–4 mm, with nicely contrasting colours at least in early capitula, with a narrow, to 1 mm wide, dark green to blackish green middle strip, ± abruptly changing into light olivaceous-green main part of the phyllary’s surface, usually to 2 mm wide on each side, with a white border 0.1–0.4 mm wide, glabrous, entire, distally suffused purplish, apex minutely corniculate, adaxial surface paler and more glaucous; inner phyllaries 12–15 mm long, of slightly unequal width, ± flat. Outer ligules ± flat, striped purplish grey-olivaceous outside, with apical teeth blackish grey abaxially, adaxially purplish, inner ligule teeth dark yellow or pinkish. Stigmas light to deep yellow, with pale or partly purplish pubescence. Anthers polliniferous or without pollen (in whole populations), pollen grains irregular in size. Achenes light greyish stramineous-brown or yellowish light brown, 4.3–4.7 × 1.0–1.2 mm, body with numerous thin and several thicker, long, conical spinules (the longest ones to 0.3 mm long) in upper 1/3, otherwise ± tuberculate to smooth, body subabruptly narrowing into a subcylindrical to cylindrical cone 0.5–0.7 × 0.30–0.35 mm; beak 8–12 mm long, thin, pappus dirty white to very pale brownish white, ca. 7 mm long.
