Perennial. June — October. 



An intermediate species between the preceding and the following, 

 though perfectly distinct from both. Rout tufted, black. Fronds 

 numerous, from three to six inches high, smooth in every part, 

 with blackish shining stalks; the leaty portion about equal to 

 the stalk, lanceolate ; leciflets alternate, stalked, of a narrow 

 wedge-shaped figure ; bluntish and notched at the summit ; 

 two or three of the lowermost slightly compound. Masses two 

 or three on each leaflet, linear ; their covers opening towards 

 the main rib of the leaflet, or segment. 



The nomenclature of this species, a native not only of Germany, 

 but of Switzerland, Sweden and Scotland, evinces the folly ot 

 specific nam.es taken from any particular country j but more 

 especially the still greater folly of restoring oIJ names, which 

 had been laid aside on account of their badness, and long since 

 forgotten.
