A good species distinct from Diplazium japonicum (Thunb.). Though 

 it resembles the latter in its general habit, it clearly differs from it by 

 the texture of the frond, the form and colour of the scales, the presence 

 of petioles to the pinna3, the length of the sori, the stiffness of the rhizome, 

 and the stoutness of the roots. This is found especially in shady places 

 of the mountains in the southern parts of Japan, while D. japonieum 

 commonly grows in the exposed situations of fields and hill-sides throughout 

 the country. 



Diplazium japonicum ( = Asplenium japonicum Thunb.) is entirely 

 herbaceous in texture.
