THIS is very like the last species, and is perhaps 

 only a variety, but the segments are much narrower. 

 It grows in little tufts. The whole frond is narrow 

 usually simply pinnate with the lower segments 

 three -lobed, or very rarely bearing three distinct 

 segments. The pinnae have two or three distinct 

 lines of sori crowded on their under surface, which 

 ultimately meet in the centre. The indusium is entire 

 at the edge, not jagged, as in the Wall Rue. 



This is, perhaps, the rarest of our British ferns. It 

 has very seldom been found in England, Wales, or 

 Ireland, and rarely in Scotland. Mr. Newman men- 

 tions three localities there where it has been gathered ; 

 viz. near Dunfermline, Dunkeld, and on rocks on 

 the Tweed, two miles from Kelso. In other parts 

 of Europe it is occasionally seen, but grows very 

 sparingly.
