grass penetrate so deep that a considerable part of theni 

 would escape ; and the least particle of the root soon ])ro- 

 duces a plant. 



Flowers in the second week of August, and the seed is 

 ripe about the latter end of September. 



AGROSTIS stolonifera aristata. Awned Creeping Bent.

Obs. — The first knowledge I had of this variety was 

 from the Duke of Bedford, who pointed it out on 

 Priesley Moor. I have since found it common on 

 peaty moors. It can scarcely be distinguished from 

 the agr. stolonifera latifolia without examining it in 

 the hand. The runners or stolones extend to a great 

 length ; they are of a brighter reddish colour than those 

 of the latifolia, and every part of the plant is rougher. 

 From these few marks of distinction this variety may 

 have been overlooked, as I find no mention made of it 

 in the botanical works to which I have had access. 



Native of Britain. Root perennial. 



Experiments. — At the time of flowering, the produce 

 from a bog soil is 8,848 lbs. per acre. 



The weight of nutritive matter in which the crop taken in 

 December exceeds that of the crop when the grass is in 

 flower, in the proportion nearly of 10 to 13, is 70 lbs. 



This variety of creeping bent is therefore greatly inferior 

 to the larger-leaved variety (agrostis stolonifera latifolia), 

 or fiorin ; for the weight of nutritive matter per acre aflurded 

 by the latifolia is two-thirds greater than that of the awned 

 variety. Cattle appear to eat this grass in common with 

 the rough-stalked meadow-grass and meadow foxtail-orass. 



It flowers about a week later than the fiorin, but the seed 

 is ripe about the .same time. 



AGROSTIS stolonifera ungustifolia. Smaller-leaved Creep- 

 ing Bent. 



Var. '3. — Panicle densely crowded with florets ; florets 

 small; inner valve of the calyx smooth, the outer
