The proportional value in v^rhich the grass, at the time of flowering, 

 exceeds that at the time the seed is ripe, is as 8 to 5.

The proportional Value, in which the grass at the time of flower- 

 ing exceeds that of the latter-math, is as 4 to 1 ; and the grass, at 

 the time the seed is ripe, exceeds that of the latter-math in the 

 proportion of 5 to 2. 



From the above details, which shew the produce and nutritive 

 qualities of this grass, it appears to be inferior to the Festuca du- 

 riuscula, which will be manifest on a comparison of the former 

 details respecting the Festuca durinscula with the above. In re- 

 gard to early produce, however, this grass is superior. The herb- 

 age is uncommonly fine and succulent. But these merits appear 

 hardly sufficient to compensate for the deficiency of produce. If 

 its merits be compared with those of some of the early grasses, 

 the Anthoxanthum odoratnm for instance, it will be found superior.

Though this grass cannot be recommended in preference to the 

 Festuca duriuscula, yet it is evident, from the above details, that 

 among the fine-leaved fescues, it is the best substitute for that 

 species where it is wanting. It is not so common as the Festuca 

 duriuscula, being more confined to the moist spots of the pastures, 

 though occasionally found also on the drier places, in company 

 with it. Flowers in the second week of June, and ripens the seed 

 in the second week of July.
