Culms forming small compact tufts, slender, leafy below, naked and 
filiform above, smooth and glabrous, 1-3in. high. Leaves much 
shorter than the culms, pale glaucous-green; blade +3 in. long, 
very narrow, filiform, involute and almost terete, grooved down the 
back, obtuse at the tip; sheaths broad, pale, membranous, grooved ; 
ligules long, broad, hyaline, often bifid or irregularly lacerate. 
Panicle reduced to an oblong spike-like head +—4in. long of 4-12 
spikelets. Spikelets pale glaucous-green, about +in. long, ovate, 
4—7-flowered. Two outer glumes subequal, ovate-oblong, acute, 
the lower 1-nerved, the upper 3-nerved with the lateral nerves faint. 
Flowering glumes ovate-oblong, obtuse, faintly 3-5-nerved, the 
lateral nerves sometimes obsolete, silky all over with very short 
crisped hairs. Palea shorter than the glume, linear-oblong, silky 
on the keels. Anthers oblong, very minute, about +, in. long.

compressed, leafy, 2-8in. high. Leaves numerous towards the 
base of the culms and sheathing their whole length, much shorter 
than them, glaucous or greenish-grey, everywhere rough with 
minute projections; blade 4-2in. long, narrow, folded, 4,4 in. 
broad when spread out, rigid and coriaceous, acute or almost

acute, 3-nerved, the lateral nerves faint. Flowering glumes broadly
