160 HORTUS GRAMINEUS WOBURNENSIS 



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 ?

 The weight of nutritive matter which is lost by leaving 

 the crop till the seed be ripe, exceeding one-half of 

 its value, is 217 12 



The proportional value in which the grass at the time of flower- 

 ing 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 

 accounted 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
