 panicle, containing 5 - 10 or more flowers, the lower palet with a short bristle 

 point or an awn from the blunt rounded tip or notch, the upper palet soon adher-

 fields ; nearly smooth ; panicle open and spreading, even in fruit ; spikelets 

 turgid r flowers laid broadly over each other in the two ranks; lower palet 

 convex on the back, concave within, awnless or short-awned. ® ®

 in the wind, — whence the common name. ® , 



<- H- +i Grain and Meadow-Grasses, with a mostly tuu'sted or bent awn on the 

 back of the lower palet : flowers 2 or 3, or few in the spikelet, and mostly 

 shorter than the glumes.

 its lower palet bristle-pointed from near the tip, and above that a rudiment of a 

 third flower, y. 



H61CUS lanitUS, Velvet-Grass, or Meadow-Soft-Grass. Introduced 

 from Eu. into meadows, not very common, 1^0-2° high, well distinguished by 

 its paleness and velvety softness, being soft downy all over ; panicle crowded ; 

 the flowers only 2 in the spikelet, small, rather distant, the lower one perfect 

 and avniless, the upper staminate and with a curved or hooked awn below the 

 tip of its lower palet. 2/ 



§ 2. Spikelets either strictly spiked or in a panicle so contracted and dense as to 

 tmilaU a spike. {Here would besought one species of Cala.magrostk3 and
