Scapes brownish green, usually suffused pink, arachnoid, scarcely overtopping leaves. Capitulum yellow, ca. 2.5–3 cm wide. Involucre light greyish green, slightly or not pruinose, 8–9 mm wide and ± rounded at base. Outer phyllaries 12–17, not imbricate, arcuate-reflexed or arcuate recurved to arcuate, linear-lanceolate to lanceolate, usually (6–) 7–9.5 (–11) × 1.9–3.0 mm, abaxially light grey-green with a narrow whitish-green border ca. 0.1 mm wide and a darker grey mid-vein, pruinose, margins glabrous or very sparsely and minutely ciliate, apex ± callose; inner phyllaries 12–13 mm, later to 15 mm long, apex ± callose.
