Bentham observes as follows: *' Milium was formerly extended 

 to sever;;! uiuiwned Panicete with only two empty glumes, but it is 

 now reduced to five or six species, all removed from Panicaceai as 

 having the empty glumes persistent below the articulation. Tliey 

 differ from Oryzopsis chiefly in their obtuse absolutely unuwned 

 flowering glume."
