"Plants relatively small, 8–13 cm tall, fruiting scapes to 30 cm tall. Petiole suffused greyish purple, winged to very broadly winged, 1.5–2 cm long; plant base without tunic, with subdense dirty white hairs. Leaves subpatent to erect-patent, lighter glaucous-green, often suffused brownish-purplish, almost glabrous, not spotted, mid-vein brownish-purplish, narrowly elliptical to narrowly oblanceolate, 5–9 × 1–2.3 cm, ± not divided, only denticulate in some outer leaves, otherwise pinnatipartite to pinnatifid, with 2–3 usually irregular pairs of subrecurved to distally subpatent, deltoid to broadly triangular, acute to acuminate lateral segments 5–10 × 8–10 mm, distal margin subconvex, subconcave or slightly sigmoid, usually with a single little tooth or entire, proximal margin concave to ± straight, entire; interlobes short to medium long, usually 3–8 × 4–7 mm, ± entire, not aberrantly coloured but usually narrowly bordered purplish; terminal segment triangular or variously helmet-shaoped, sometimes with a lingulate tip, usually 1–2 × 0.8–1.5 cm, acute, distal margin undulate or slightly concave or subsigmoid, entire or with with a minute proximal tooth or an incision, basallobules ± patent to subrecurved, or subhastate, ± acuminate, often asymmterical, proximal margin ± straight, entire. Scapes usually purplish at base and distally, otherwise pale green, sparsely arachnoid, ± overtopping leaves. Capitulum yellow, 3.5–4 cm wide, flat to subconcave. Involucre greyish olivaceous-green, slightly pruinose, ca. 9–10 mm wide and ± truncate at base. Outer phyllaries 10–13, ± loosely appressed, ± not imbricate, ovate to lanceolate, 7–8 × 2.5–3.5 mm, dark olivaceous-green (almost blackish when dry), distal 1/3 suffused purplish, with a translucent, dirty whitish border 0.1–0.35 mm wide, margin sometimes remotely denticulate, ± glabrous, apex ± flat, adaxial surface paler, light glaucous-green and suffused pinkish, later darkening; inner phyllaries 11–12 mm long. Outer ligules flat, broad, faintly striped very pale greyish-pinkish outside, with greyish apical teeth, inner ligule teeth deep yellow. Stigmas pure light yellow, with hyaline pubescence outside; anthers polliniferous, pollen grains irregular in size. Achenes light grey-brownish, relatively small and thick, 4.2–4.5 × 1.0–1.1 mm, body not conspicuously sculptured, sparsely spinulose to ± wrinkled in upper 1/5–1/4, body ± subabruptly narrowing into a relatively thick cylindrical cone 0.9–1.2 × 0.35–0.45 mm, sometimes with a little spinule at base; beak thin, 6–7 mm long, pappus dirty whitish, 6–7 mm long.
