CHAPTER XVIII 



TRIBE VI. ORYZE^E 



THIS is one of the smaller tribes, the 

 place of which among 

 the other tribes is 

 not evident. Neither 

 is it in itself a natural 

 group, but is made 

 up of genera of diverse 

 affinities. Certain 

 anomalous genera, 

 such as Pharus (Fig. 

 29) Streptocha3ta and 

 Reynaudia, included 

 by Hackel and by 

 Baillon in Oryzese are 

 referred by Bentham 

 and Hooker, the first 

 two to Panicese and 

 the third to Triste- 

 ginese. The articula- 

 tion of the spikelets 

 below the glumes in- 

 dicates an alliance 

 with the first series 

 of tribes, PanicoideaB;
