 There are many forms, characterized by narrow almost setaceous or by very short 

 leaves, by very narrow and contracted panicles, by shorter spikelets, or by various 

 combinations of these characters ; but these are all so intricately connected, and m 

 mauy cases so evidently the product of conditions of habitat, and are so independent 

 of geographical distribution, that it is impossible to define them satisfactorily. 

 The two extreme forms are —
