AIR A CAESPITOSA I*.~(Tufted Hair Grass.) 



Stems erect, round, rough, 

 and in tufts; leaves flat, linear, 

 acute, sheaths striated, rough- 

 ish, the upper one longer than 

 its leaf, pyramidal, oblong; 

 panicle large and drooping, 

 but becomes erect as it ripens, 

 and its branches spread in 

 every direction. Short awns. 

 It is like the "Wood hair 

 grass," only in the latter the 

 awn of the lower floret does 

 not protrude beyond the 

 glumes. 



It is peculiar to marshy 

 lands especially where water 

 stands, and may often be seen 

 in meadows or pastures, form- 

 ing large unsightly tussocks 

 over the field. Cattle will not 

 eat it at all.

 lets seven flowered; lower palet broadly ovate, hairy on the 

 back, longer than its awl-shaped teeth.

HORDEUM PRATENSB, "Kuds. -(Squirrel-Tail Grass).
