Systematics

Description

"Plants small, usually 5–12 cm tall. Petiole usually green, sometimes pinkish, narrow, unwinged, sparsely arachnoid to ± glabrous; plant base almost glabrous, without tunic. Leaves deep green, usually with pale green mid-vein, ± linear to narrowly oblong-linear in outline, most frequently (4–) 5–7.5 (–10) × 0.7–1.2 (–1.9) cm, at least initially sparsely arachnoid, later often ± glabrescent, usually pinnatisect, with (4) 5–7 pairs of patent to subrecurved, most often linear (4–6 × 1–1.5 mm, in outer leaves to 5 mm wide) to ± triangular lateral segments with margins ± straight, entire, apex subobtuse; interlobes ± distinct, narrow, entire; terminal segment linear to linear-triangular, usually 0.7–1.5 cm long, subacute to ± subobtuse, entire, with small, ± linear, patent to subrecurved basal lobules. Scapes brownish green, usually suffused bronze-purplish, arachnoid, mainly distally, later often glabrescent, slightly overtopping leaves. Capitulum yellow, usually 1.5–2 cm wide, often not fully opening. Involucre deep grey-green, not pruinose, most often 6–8 mm wide and narrowly rounded at base. Outer phyllaries usually (10–) 12–14 (–18), ± not imbricate, ± lanceolate (from ovate-lanceolate to linear-lanceolate), usually 5.5–7.5 (–8.5) × (1.5–) 2.3–2.9 mm, appressed, some loosely so, with whitish membranous, distally reddish border (0.2–) 0.3–0.5 (–0.7) mm wide, with a ± gradual to ± abrupt transition in the dark green median part, margins ± not ciliate, often ± denticulate, apex most often corniculate, reddish; inner phyllaries 10–12 mm long, callose. Outer ligules subtubular to canaliculate, rarely almost flat, striped grey-purple outside, inner ligule teeth dirty yellow to dirty pinkish. Stigmas grey-yellow, with dark grey short pubescence outside. Anther polliniferous; pollen grains irregular in size. Achenes light greyish stramineous-brown, (3.1–) 3.5–3.9 (–4.2) × 0.7–0.9 (–1.0) mm, body sparsely spinulose in upper 1/3–1/2 (spinules remote, thin, straight or curved upwards, mainly situated on ridges), very gradually narrowing into a thick conical to subconical cone 0.5–0.8 mm long, often with a few spinules near its base, 0.5–0.6 mm thick proximally, 0.4–0.5 mm distally; beak ± thickened or thin, 3.5–5 mm long, with a gradual cone-beak transition; pappus ± yellowish, 4.5–5 mm long. Agamosperm."
