Spikelets in ib of 3 at the nodes of the disarticulating (except 
in cultivated forms) rhachis of a dense spike; r achilla tough, 
produced as a aca ay the me sometimes ee a rudi- 
mentary valve. Flore¢ 1, g in the intermediate spikelet, oor 
barren (¢ sometimes in ee races) in the lateral. Glum 
subulate or bristle-like or narrowly linear and awned, rigid, 1 =

kind of involuere. Valves lanceolate, subinvolute, rounded on the 
back, gradually produced into a bristle-like awn, 5-nerved. Pale about 
as long as the valve (exclusive of the art), 2-keeled, narrowed,
