Description

"Plants relatively small to medium-sized, 8–15 cm tall. Petiole greyish-purplish at base, winged to broadly winged, usually 2–3.5 cm long, sparsely arachnoid; plant base without tunic, with brownish indumentum. Leaves variously erect-patent, greyish glaucous-green, with mid-vein proximally brownish-pinkish, blade not spotted but with a conspicuous brown-purple interlobe coloration, sparsely arachnoid, narrowly oblong to narrowly oblanceolate, 7–12 × 1.5–2.5 cm, pinnatipartite to pinnatisect, with (2) 3 pairs of relatively short, subrecurved lateral segments usually 5–10 × 6–13 mm, of bird-wing shape or hamate, sometimes deltoid triangular, acuminate, distal margin sigmoid or convex, less often ± straight, entire, proximal margin ± convex or straight, entire, rarely with a single little tooth near the segment base; interlobes short, medium long proximally, usually 1–7 × 2.5–8 mm, interlobe surface conspicuously blotched brown-purple, entire or with 1–2 little thin teeth; terminal segment helmet-shaped to triangular, usually 0.8–1.7 × 0.7–1.6, acute to subacute, sometimes with a short, ± mucronate-lingulate tip, distal margin convex to sigmoid, usually entire, sometimes with an asymmetrical incision, basal lobules recurved to hamate-recurved, acute to acuminate, proximal margin most often ± straight to subconcave, entire. Scapes purplish or bronze at base and distally, otherwise pale green, arachnoid, later sparsely so, shorter than leaves. Capitulum yellow, later suffused pinkish, ca. 3.5 cm wide, ± flat to concave. Involucre slightly pruinose, ca. 7–9 mm wide and rounded at base. Outer phyllaries 12–15, initially loosely appressed, later subappressed only near the base and distally arcuate-patent or erect-patent to patent, ± not imbricate, ovate to lanceolate, 6–9 × 3–5 mm, adaxially with a dark olivaceous-green middle strip, initially narrow, later broadening to cover most of the phyllary surface, with a gradual transition into a deep or light olivaceous-green part and a dirty whitish-membranous border 0.2–0.4 mm wide, margin sparsely ciliate, entire, apex slightly callose; inner phyllaries 11–12 mm long, of ± equal width, ± flat. Outer ligules ± flat, striped dark or pale pinkish grey-olivaceous outside, with apical teeth grey-purplish, inner ligules shorter towards capitulum centre, their teeth dark yellow to purplish. Stigmas pure yellow, with a hyaline or hyaline and purplish pubescence outside; anthers polliniferous, pollen grains irregular in size. Achenes deep brown or cinnamon brown, with a reddish tinge, 4.5–5 × ca. 1.1 mm, body, in upper 1/3–1/2, with subdense erect-patent (sometimes slightly recurved) spinules often broad at base and relatively short (to 0.25 mm), body gradually narrowing into subcylindrical to cylindrical cone 0.6–1.0 × 0.25–0.35 mm; beak thin, 8.5–9.5 mm long, pappus dirty white, ca. 6.5 mm long. Agamosperm."
