Spikelets one- to seveial-llowered iu one-sided spikes or racemes ;

A small tribe of twenty-seven uenera and one hun- 

 dred and lift\ -tive si)e('ies. eharaeteri/.ed ehietly by the 

 intloresceiu'e, which is nearly that of l^hsixtliim. The 

 awns when present are not dorsal nor twisted, as iu 

 Agrostidea' and Arcncn: Chiefly natives of tropical 

 and subtropical countries; a few are widely distributed 

 as weeds throughout the warmer ])arts of the world. A 

 number are good turf-forming grasses, and are valued 

 for grazing i)urposes. One of tlu'se is the celebrated 

 butlalo-grass of the Western plains, which is remark- 

 able for having the staniiiuite and pistillate spikelets 

 separate and in unlike inflorescences, either uj)ou the 

 same plant (moncvcious) or upon diflerent plants (di(e- 

 cious).
