An erect glabrous perennial with a short horizontal rhizome covered 
with scale sheaths which tend to break up into fibres. Stem bases 
covered with leaf-sheaths of which the outermost tend to become 
fibrous at the base; sheaths closed with truncate mouth; blades 
linear tapering in the upper part to an acuminate apex, up to 2 ft. 
jong and 2 in. broad but usually much less, midrib conspicuous 
and sharply keeled below, 2 lateral veins prominent on the upper 
surface. Flowering stem sharply triangular. Inflorescence a com- 
pound umbel with primary rays up to 7 ins. long (very unequal) ; 
primary bracts numerous leaf-like, very various in length and breadth, 
3 or 4 usually longer than the inflorescence; ultimately the spike- 
lets arranged in a spicate manner. Spikelets linear about < in, long 
and 5 in. broad, pale brown in colour ; each internode of the rhachis 
laterally flattened with a broad hollow which holds the nut and is 
surrounded on two sides by hyaline wings. The two lowest glumes 
usually empty and reduced flowering glumes elliptic when spread 
out, acuminate, with a broad keel. Stamens 3. Nut ellipsoid-
