HERB with a very short-branched woody rootstock, the upper parts covered by foliar remains.Scapes 5–15 cm, curved. Leaves 15–40×(1.2)1.5–4(4.5) mm, monomorphic, concentrated at the end of the rootstock branches, sublinear to linear-lance-olate, (1)–3-veined, obtuse to subacute, with a narrow scarious
ciliate margin (cilia c. 0.1mm), with white salt crystals scattered on the surface. Involucral sheath 4–9(11)mm.INVOLUCRE 13–16mm in diameter. Involucral bracts 10–13, straw-coloured, the outer shorter than the inner, the middle and inner awnless.SPIKELET bracts clearly visible within the involucre widely scarious, with a green central portion, without purple subapical spot. CALYX 6.2–7.2mm long, pubescent on the 10 ribs (hairs 0.3–0.6mm); lobes 1.2–1.6mm (including the awn); tube 2–2.8 mm; scarious limb 2.3–3mm, frequently tawny-coloured, pedicel scar 0.3–0.5 mm. COROLLA purplish-pink.
