The annual species of this genus have been introduced from 

 Europe and are more or less serious pests. The native species are 

 perennials mostly confined to woods and shady places and are of no 

 economic importance. The spikelets are large, usually many-flowered ; 

 the lemmas are two-toothed at the apex and often bear an awn from 

 between the teeth ; the glumes are unequal, the second larger. The in- 

 florescence is of panicles, the spikelets either erect or drooping. The 

 leaves are flat, the ligules membranous, seldom over 1 or 2 mm. in 

 length. The species are exceedingly variable, and therefore difficult 

 to classify correctly.
