We distinguish the three varieties as follows : 



(1.) Spikelets numerous, generally in glomerate heads; perigynia 

 mot recurved at the tips at maturity. 



(2.) Spikelets fewer, more scattered, and the perigynia with recurved 

 .tips at maturity. 



(3.) Spikelets small, very much scattered (moniliform), perigynia 

 .spreading, or recurved at the tip.
