A single glance at the fertile pinnae of this fine species, 
is sufficient to assure any one of its distinctness from S. 
Germanica, of Willdenow (Pensylvanica of the U. States 
Botanists) ; not only are they much longer and broader and 
flatter, (less cylindrical) and never monihform ; 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 pinnae 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 Ferns; and it appears 
again in the Northern Island of Japan, Hakodadi.
