We distinguish the three varieties as follows : — 



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

 not recurved at the tips at maturity. 



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

 tips at matui-ity. 



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

 .spreading, or recui-ved at the tip.
