 Lindley, Synopsis, p. 281. 



A small plant, growing in dense tufts. lioots numerous, tough, and 

 wiry. Stem erect, slender, simple, striated, varying in height from two 

 to ten inches, naked, except at the hase, which is enveloped in two or 

 three sheaths hearing suhulate leaves, and surrounded with numerous 

 smooth brown striated scales. Spike small, ovate, reddish-brown, two 

 outer glumes largest, longer than the spike, mostly with a foliaceous 

 apex, and generally fertile. Fruit triangular, pale yellow, terminating 

 in a fine point, and surrounded at the base by six bristles, longer than 

 itself. Dr. Hooker finds a varietij upon Ben Lawers, with the two 

 outer glumes an inch long, four times the length of the spike. 



Habitat. — Common on moors and moist turfy situations. 



Perennial ; flowering in June and July, 



This species grows most abundantly on moist barren moors in many 

 parts of the country, and is fed upon by sheep, and " is called ' Deer's 

 Hair' in the Highlands, and yields an abundant food to sheep on the 

 mountains in spring." Hook.
