Near Vittaria arisanensis HAYATA, but quite distinguishable from it by tbe 

 blackish scales of the rhizomes. Also near Vittaria suberecta HAYATA, but 

 differs from it in having very much thinner margins and thinner texture ; 

 from V. japonica, the present species is distinguishable by the cellular structure 

 of the scales, which are a little darker than those of V. japonica.
