As regards to the indusium, W. sinuata (Hooker) apparently belongs 

 to the sect. Euivoodsia, but as to the articulation of the stipe, it is 

 similar to that of W. polystichoides Eat., which is placed within the sect. 

 Physematlum by many authors. 



There is a plant from the Namsan of C(.rea in the herbarium of the 

 Sc. Coll. Imp. Univ. Tokyo, collected by T. Uchiyama. It approaches very 

 much to W. sinuata (Hooker), having the indusium of W. polystichoides 

 Eaton.
