''The spikelets in the three last preceding species are broader 

 upwards and bear long, straight, very conspicuous awns. Maximus 

 has a very simple, erect panicle with few lai-ge sjiikelets on short, 

 stoutish, often undivided branches ; sterilis is similar, but with much 

 smaller spikelets and more slender, longer branches, becoming 

 recurved; tectorum has numerous still smaller and proportionately 

 narrower spikelets, on rather short, filiform, droo))ing and often 

 secund branches, and foliage velvety pubescent." Dr. C. W. Swan.
