 Sea-side brome grass. Nat. of Germany, 

 grows on the banks of the Danube and 

 other rivers.

The proportional value which the grass at the 

 time of flowering, bears to that at the time the seed is 

 ripe, is as 6 to 14. 



This species greatly resembles the preceding in 

 habit and manner of growth; but is inferior to it in 

 value, which is evident from the deficiency of its pro- 

 duce, and of the nutritive matter afforded by it. The 

 whole plant is likewise coarser and of greater bulk in 

 proportion to its weight. The seed is affected with 

 the same disease which destroys that of the former 

 species,
