Synflorescence of 1–6 flowering heads, with rather short slender final branches (central one is not strongly abbreviated). Phyllaries narrowly triangular, with acute apex, 10–11 mm long, dark-olivaceous, with rather dense blackish simple hairs ca. 1 mm long, rather dense stiff glandular hairs 0.3–0.8 mm long and sparse stellate hairs in the basal part, with very narrow glabrous margins, apex with a few ciliae.
