160 nORTUS GRAMINEUS M'OBURNENSIS. 



Festuca ovina. I am uncertain as to its native place of 

 growth, having never discovered it in any soil or situation in 

 a wild state. The culms are strongly marked with ribs. 

 Root fibrous, perennial. Native of Britain ?

its value, is - - - - - 217 12 



The proportional value in which the grass at the time of flowering 

 exceeds that at the time the seed is ripe, is as 9 to 7 ; and it exceeds 

 the value of the latter-math grass in the like proportion. The 

 grass of the seed crop and that of the latter-math are equal in the 

 quantity of nutritive matter they contain ; a circumstance easily ac- 

 counted for, as the culms at the time the seed is ripe are drier than 

 in most other grasses at the same stage of growth ; and the produce 

 then consists almost entirely of leaves, similar to the latter-math 

 produce. This species flowers earlier than any other of the fescue 

 species. Its nutritive qualities are nearly the same as those of the 

 Festuca duriuscula. It is superior to that species and to most 

 others in the produce of early herbage in the spring ; the herbage 

 is very fine, tender, and succulent. It is highly superior to the 

 Festuca ovina, of which it is considered a variety. It does appear
