which is evident from the deficiency of its produce, 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.

This species of fescue is closely allied to the Festuca 
pratensis , from which it differs in little, except that it is 
larger in every respect. The produce is nearly three times 
that of the F. pratensis, and the nutritive powers of the 
grass are superior, in direct proportion, as 6 to 8.
