Synflorescence of 3–5 flowering heads, with rather short slender branches (central one is abbreviated). Phyllaries narrowly triangular, with acute apex, 10–11 mm long, dark-olivaceous, with very rare to rare blackish simple hairs 0.5–1 mm long mostly at the base, rather dense to dense glandular hairs 0.5–1 mm long and sparse stellate hairs in the basal part, with sparsely pubescent or glabrous margins, apex with a few ciliae. Synflorescence branches with solitary simple hairs up to 1 mm long, dense slender glandular hairs 0.5–0.8 mm long and stellate hairs. Styles with black papillae. Ligules glabrous.
