 sessile, simple or pedicelled compound one in the centre. 

 Spikelels most numerous, imbricated, lanceolate, from eight 

 to twelve-flowered. Involucre many-leaved, some of them 

 nearly as long as the culm, and like the radical leaves keel- 

 ed and armed on the margins. Involucels scarcely so long 

 as their respective umbellets. Scales of the spikelets boat- 

 shaped, with membranaceous margins, and sharp thickened 

 points. Stamens three. Seed oblong, obsoletely three-sided.
