The grass of the latter-math, 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 propor- 



tion 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; hut 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 



r 



of the Festuca ovina. It ripens a sufficiency of seed, which vegetates freely. Its nutritive powers 

 are inferior to those of the Festuca ovma, in the proportion of 3 to 2. From all which, it at pre- 



r 



sent appears to he one of the most inferior kinds of grass. 



i 



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

 weeks of July. 



Festuca glauca. Glaucous Fescue-grass. 



Specific character: Panicle rather spreading; spikets spear-shaped, awned; culms and leaves 

 smooth. Whole plant glaucous. 



r 



Obs. — This plant diifers from the Festuca glauca of Host. (t. 88) in the stem, which is round, 

 smooth, and straight. The leaves are longer and smooth. The spikets less spear-shaped; 

 the panicle is contracted before and after flowering: spikets 5-7 flowered; awns short 

 and rigid. Mr. Curtis, in his enumeration of British grasses, mentions this as indigenous, 

 and on this authority it is here entered, as I never could find it in its natural state. 

 There is another Glaucous Fescue in the Wohurn collection, which differs from this one 

 in being in every respect smaller, and of a much deeper glaucous colour; the root-leaves 

 are vejry short, and bent inwards. 



Native of Britain. Root perennial, fibrous.
