A densely tufted perennial, mostly 15-45 cm high, with oblique to erect, often flexuose slender wiry stems c. 2 mm thick; leaves present or reduced to glossy-brown basal sheaths, these deeply split or quite open, oblique and sometimes mucronate at the apex, ciliate on the margins.

Nut ovoid-pyriform, obtuse, cuneate to a beak-like stipe, c. 2 x 1.3 mm, hardly trigonous, nearly hemispherical at the top, not at all ribbed except at the very base, rather tawny and spotted with red, smooth, dull, about half the length of the glume.
