Gen. Char. Inflorescence panicled; panicle contracted, spike- 
like. Spi/ie.lets (fig. 1.) single-flowered. Calyx (fig. 1.) of two 
nearly equal, concave, keeled, pointed, membranous, awnless 
glumes, ventricose at the base, much longer than the palete. Co- 
rolla (fig. 3.) of 2 equal, membranous palece ; the lower usually 
awned under the apex. Sometimes there is a rudiment of a se- 
cond floret at the back of the upper palea. Filaments (see figs. 1 
and 3.) 3, hair-like, not longer than the calyx. Grmen (fig. 4.) 
egg-shaped. Styles (see fig. 4.) 2, pencel-shaped. Seed (fig. 5.) 
egg-shaped, coated with the hardened corolla. 
The contracted, spike-like panicle ; the single-flowered spike- 
lets ; the calyx of 2 nearly equal, awnless, ventricose glumes, much 
longer than the corolla ; and the corolla of 2, equal, membranous 
palese, investing the seed, the lower one mostly with a dorsal awn ; 
will distinguish this from other genera in the same class and order. 
One species British.
