 At the foot of the rocks among the highland 

 mountains, but not very frequent. We ga- 

 thered it in plenty at Creg-a-cknocaen, the boun- 

 dary of Coygach and JJJyni, on the borders of 

 Sutherland, near the vveftern coaft. Mr. Sfuar: 

 obferved it among the mountains of Breadalbane^ 

 and Sibbald in Kinneil-Bank, % • 

 The leaves vary from three to eight inches 'm 

 length, and are ftiff and rigid. The ftalk and 

 middle rib are covered with brown filmy frales. 

 The pi?2?i^ arc fupported en very Ihort but vifi- 

 ble footftalks, their upper edge (lightly curved 

 in a concave arch, the lower edge in a convex 

 one, edged with ferrated fpinulcs. Th^ pinj^ 

 are truncated at the bafe, their upper angle is 

 elevated, but the lower one as it were refcinded, 

 and deftitute of fpinules. The frudtifications 

 grow in two feries of circular dots, upon ten or 

 twelve pairs of the uppermoft pinna \ but the 

 lowermoft, which are about as many more, are 

 barren. The fcale, or involucrum, which covers 

 each dot, is pekated. The capfules are globu- 

 lar, fupported each on a footftalk, and contain, 

 ing each a fingle feed, according to Gleditfch.
