Bentham observes as follows: '* Milium was formerly extended 

 to several unawned Panicese with only two empty glumes, but it is 

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

 having the empty glumes persistent below the articulation. They 

 differ from Oryzoims chiefly in their obtuse absolutely unawned 

 flowering glume."
