buncihes. It has a wide range on sandy soil jind gravelly hills. It is the 

 only grass in this section which alVords forage for wild or domestic animals, 

 and as it is generally found (as shown by many of these sjiecimons) denitd(>d 

 of its leaves, while the dowers and seed-tops reinaiu intact, Ibe inference 

 would bo that wild animals (domestic animals are few here) crojt the lea\<^s
