DESCRIPTION. 



An annual, or sometimes perennial grass, growing three to four feet 

 high under favorable conditions and sending up several stems from 

 the same base. The pani- 

 cle is usually large and 

 spreading, bearing much 

 flattened spikelets about 

 one inch long and one- 

 quarter of an inch wide, 

 composed of seven to ten 

 florets overlapping each 

 other. The flowering 

 glumes are rather coarse 

 in texture, strongly 

 nerved, and usually bear- 

 ing a short i>oint or awn 

 rarely exceeding an eighth 

 of an inch in length. The 

 "seed," in the commercial 

 sense of the term, repre- 

 sented in fig. 1, b, consists 

 of the flowering glume 

 with the inclosed palet and 

 grain. 



Ther(? are several forms 

 in cultivation , varying 

 somewhat in the size of the 

 panicle and the length of 

 its branches, also in the 

 length of the awn on the 

 flowering glume. T he 

 form illustrated in the fig- 

 ure is the one to which the 



name Bromus .schrader-i has been especially applied, 

 from the typical form only in having the branches somewhat longer 

 and more drooping.
