Sheaths straw-coloured, more or less persistent, closed; blades several, on the stem, the lowest more or less reduced, often to mere scales, the others slender and elongate, folded or triangular in cross-section to thick and flat, 0.3-1 mm wide.
Inflorescence of 1 to 3, compact, axillary or terminal heads, mostly 5-15 mm wide, the terminal head larger than the others, each head with several to many spikes, the spikes white, becoming pale brown, often with a whitish or pinkish tinge, mostly 3.5-5 mm long, 2- to 3-flowered; involucral bracts longer or shorter than the inflorescence, 0.5-6 cm long.
Scales egg-shaped or lanceolate, pale brown, translucent on the margins, spirally arranged within the spikes; perianth bristles 10 to 12, well-developed, minutely finely barbed backwards, surpassing the achene bodies and sometimes also the tubercles; achenes lens-shaped, 1.5-2.5 mm long; broadest above the middle, tapering to narrow, nearly stalked bases, capped by elongate, narrow awl-like tubercles, about 1/3 to 1/2 as long as the achenes.
