Hab. — On elevated marshy situations amongst /Sy^/zr/y/zr/. Ver}' 

 rare. 15. Catlaw Hills, Kinnordy, Forfar, C. Li/cIl, 1822.

( )bs. — The description is that of the original Jfuif/. Jiibcniica 

 published by Hooker in his "British Jung."; two other forras 

 have been grouped with it which probably deserve to rank as 

 distinct species. The type is distinguished from them by its 

 much larger size, long, slender, slightly undulate fronds in 

 addition to other characters. 



Distinp^uished from Pallavicinin Li/el/ii (Hooker) by the absence 

 of a nerve in the midrib, by its strong smell in addition to other 

 characters.
