This, like the preceding species of Bromus, is strictly annual. It is much less common tha 

 the Bromus steriUs : Hudson informs us that it grows on old walls in tlie neighbourhood of Lon 

 don and Oxford. Birds seldom touch the seeds ; but this appears to be more owin^ to the 

 season in which it is presented to them, than to any defect in the quality of the seed; as there is' 

 then a profusion of food of a more welcome nature. The above details shew the produce ofthi^ 

 grass, in one year, which, when compared to that of the least valuable of Lhe perennial o^rasses 

 proves inferior, and ranks it with the grasses of little use to the Agriculturist. The panicle 

 when in flower, constitutes the principal weight of the produce: the nuLridve matter it contains 

 bears a similar proportion to that afforded by the culms and leaves conjunctly, as was shewn to 

 exist between those of the Bromus sterilis. 



It flowers in the third week of June, and the seed is ripe about the middle and latter end of 

 July.
