108 HIEROCHLOE. 



[CLAM in. cuu if. 



Habitat. Frequent in the mountainous districts in the North of 

 England and in Scotland ; plentiful at Settle, on the moors, and lime- 

 stone districts in Yorkshire and Derbyshire. 



Perennial ; flowering in April and June. 



This grass appears to be a favourite food of sheep, and is one of the 1 

 superior alpine grasses, as containing a considerable proportion of nutri- 

 tive matter; it is an early spring grass,but the quantity of herbage which 

 it produces is inconsiderable, and its growth, after being cropped, is 

 very slow. J t appears to possess no other properties by which it can 

 be cultivated with advantage in other than its natural place of growth, 

 but iu such situations it is one of the best and most nutritious grasses.
