Diagnosis

Stems 25–40 cm tall. Basal leaves pale greyish-green, oblong-ovate to lanceolate-ovate, base subrotund, apex broadly triangular to subrotund, with minute dentation along the margin, on a long petiole, with dense simple hairs 0.8–1 mm long (glabrescent in the middle); cauline leaves 1–2, one at the base similar to the basal leaves, another much reduced. Synflorescence of 2–5 flowering heads, with rather short slender final branches (central one is not strongly abbreviated). Phyllaries very narrowly triangular, with narrowly acute apex, 9–10 mm long, dark-olivaceous, with sparse to rather dense blackish simple hairs 0.5–0.8 mm long, rather dense stiff glandular hairs 0.2–0.5 mm long and sparse stellate hairs mostly along margins in the basal part, with very narrow glabrous margins, apex with a few ciliae. Synflorescence branches with solitary to rather rare simple hairs 0.5–0.8 mm long, very dense slender glandular hairs 0.2–0.4 mm long and stellate hairs. Styles with black papillae. Ligules glabrous.
