A single glance at the fertile pinna? of this fine species, 

 is sufficient to assure any one of its distinctness from 5. 

 Germanica, of Willdenow (Pensylvanica of the U. States 

 Botanists) ; not only are they much longer and broader and 

 flatter, (less cylindrical) and never moniliform ; but the invo- 

 lucre is of a very different nature, so broad as completely 

 to cover the back of the pinnules, the entire edges meeting 

 at the back, and never breaking up into uniform segments ; 

 and the texture is thin and membranaceous, but firm, very 

 glossy, and of a very dark chestnut colour, suddenly con- 

 duplicate, and pressed close to the sori on the back; whereas 

 in S. Germanica, the moniliform fertile pinna? have the invo- 

 lucre rolled back as it were, so as to cover the sori, and of 

 the same texture and color as the pinna itself. The sterile 

 frond too, which is much attenuated at the base, is here 

 abrupt. As a species, it may probably be found to have as 

 extensive a range in the Eastern, as S. Germanica has in the 

 Western world, (including Europe in this region), for it has 

 already been found in Sikkim Himalaya. I detected one 

 specimen in a collection of Assam Eerns; and it appears 

 again in the Northern Island of Japan, Hakodadi.
