Leaves probably deep green to olivaceous-green (possibly slightly glaucous-green), with dirty purplish mid-vein, narrowly oblanceolate in outline, usually 15–25 × 3–5.5 cm, subglabrous, often with scattered arachnoid hairs along the mid-vein, pinnatisect, with (2) 3–4 pairs of ± triangular to narrowly triangular, recurved to subpatent, acute lateral segments 1.2–2.3 cm long, distal margin concave or slighty concave, ± entire in distal segments, sparsely denticulate in proximal ones, proximal margin straight to ± convex, usually with sparse minute teeth, sometimes entire; interlobes broad (0.8–1.5 cm), often with a few little acute teeth; terminal segment triangular to broadly triangular, or ± helmet-shaped, with a sagittate base, entire, subacute, with basal lobules ± recurved. Scapes ± brownish green, distally arachnoid, ± equalling leaves. Capitulum yellow, ca. 2–3 cm wide. Involucre ± light green, ca. 0.8–1 cm wide and rounded at base. Outer phyllaries 9–14, not imbricate, linear-lanceolate to narrowly lanceolate, usually 6–9 × 1.7–2.3 mm, reflexed to arcuate recurved, light green to yellowish light green, with a distinct venation, with an inconspicuous membranous border 0.1–0.3 mm wide, often suffused purplish distally, margins glabrous, apex with distinct horns; inner phyllaries ca. 12–15 mm long, mid-green to paler green, apex corniculate or with horns. Outer ligules ± flat, striped dark grey-green outside, inner ligule teeth light greyish purple. Stigmas light greyish-greenish or grey-yellow. Anthers polliniferous, pollen grains irregular in size. Achenes light greyish fulvous to light greyish ochraceous, ca. 4.3–4.5 × 1.0–1.1 mm, body conspicuously, very densely spinulose in upper 1/3–1/2, otherwise at least tuberculate, spinules acute, erect to erect-patent, quite long, the longest ones 0.3–0.4 mm long, body subgradually narrowing into a cylindrical cone 0.7–0.9 × 0.3–0.4 mm (often with one or a few long spinules near its base, beak thin, ca. 9 mm long, pappus (yellowish) white, ca.6 mm long.
