Description Culms erect, terete, without nodes, grey-green, 20-60 cm high, c. 1 mm diam.
Leaf-sheaths pink-brown turning grey-brown with age, usually not shining, breaking
up with age to form a network of fibres round the base of the culms; ligule obvious,
white-membranous, to 1.5 cm long; leaf-blades reduced, to 3.5 cm long. Inflorescence
globose or hemispherical, 9-14 mm diam. Involucral bracts: 1 longer than the
inflorescence, 3-8 cm long, with a second bract opposed with a short awn; both
bracts with broad hyaline margins. Spikelets 8-10 mm long; glumes 6-7, with an
ex curved awn. Anthers 2.5-4.0 mm long, with an appendage 1.0-1.7 mm long.
Nut 2.0-2.5 mm long, 1.2-1.5 mm diam., whitish, short-ovate; gynophore yellowish
with a spreading or reduced disc. [details]
