This is an alpine species of grass, and attains to a greater size 

 than most others of the same class ; but it is a native of the Alps 

 of the fertile duchy of Carinthia, in Germany. It is rather late in 

 the produce of foliage in the spring, and does not afford much 

 after-grass. Its nutritive powers, as indicated by the quantity of 

 nutritive matter it contains, is not superior to several other grasses 

 that afford a greater abundance of herbage throughout the season. 

 It produces flowers about the first and second weeks of July, and 

 seeds in the second week of August. 



STIPA pennata. Long-awned Feather-grass. 



Generic character: Calyx 2-valved, 1 -flowered; corolla outer 

 valve ending in an awn ; awn joined at the base. 



Specific character: Awns woolly. Sm. Engl. Fl. i. p. 161. 



Obs. — Awns from six to twelve inches long or more, set with 

 very fine, soft, white, pellucid hairs. In Ray's Synopsis, 

 p. 393, this elegant grass is said to have been found by 

 Dr. Richardson and Thomas Lawson, on the limestone rocks 

 hanging over a little valley called Longsdale, about six miles 

 north of Kendal, in Westmoreland. Hudson gives no other 

 place of growth ; but in the second edition of Withering's 

 Botanical Arrangement of British plants, Mr. Alderson is 

 said to have found it near Kendal. Mr. Gough, who lives 

 near Kendal, informs Dr. Withering, that he never could find 

 nor hear of its being found by any person except the two first- 

 mentioned gentlemen ; there is therefore reason to fear that it 

 may be exterminated. (Wither. Arr.)
