It is rather doubtful that this is identical with D. 

 crenata, for there is a little difference regarding the size of 

 the stipes and the hairly state of the fronds. This 

 slightly differs from the Japanese specimen labelled 

 N. odoratum BAKER. The sori of our fern are much 

 larger than those of the Japanese.
