The weight of nutritive matter, in which the crop at

of flowering, is — - - - - 53 2 12 



The grass, at the time the seed is ripe, contains more 



nutritive matter than that at the time of flowering, 



in the proportion of 3 to 2. 



The produce of latter-math is —

The grass of the latter-raath, and that at the time of flowering, 

 contain equal proportions of nutritive matter ; and the grass, at 

 the time the seed is ripe, is superior to these, in the proportion of 

 3 to 2. 



This grass is a native of woods where the soil is dry and 

 sandy. I found it first in Aspley Wood, in 1810, whence the 

 annexed specimen. From the above details, a single crop of this 

 species is superior to that of the Festuca ovina; but it is much later 

 in the production of foliage in the spring ; and the latter-math, or 

 reproductive power of this grass, is much inferior to that of the 

 Festuca ovina. It ripens a sufficiency of seed, which vegetates 

 freely. Its nutritive powers are inferior to those of the Festuca 

 ovina, in the proportion of 3 to 2. From all which it at present 

 appears to be one of the most inferior kinds of grass. 



Flowers about the second week of June, and the seed is ripe 

 about the second and third week of July. 



FESTUCA glauca. Glaucous Fescue-grass. 



Specific character : Panicle rather spreading ; spikelets spear- 

 shaped, awned ; culms and leaves smooth. Whole plant 

 glaucous.
