Spikelets arranged in simple or panicled spikes, usually in pairs, one 
pedicellate and sterile, the other sessile, with 2 flowers, the lower imper-

Empty glumes coriaceous, the outer enfolding the inner, not usually 
awned. Flowering glume smaller, membranous, furnished usually with a 
stout twisted terminal awn. Pale like the flower-glume in texture, both of 
them smaller than the empty glumes and enclosed in them. Stamens 
usually 3. Hypogynous scales present. Styles elongated ; stigmas 
protruded from the top of the flower. Grain free. — Annual or 
perennial grasses, of very various habit, the leaves usually linear, the
