POLYPODIACE.K 



Although 1 reduced this fern as a synonym of P. stenophylluin in my 

 former paper, I think now it better to retain P. niitalcayamense for the 

 present, until I shall examine a specimen of the former. As the ferns of 

 this group are very like one another, one can not determine if they are the 

 same or not, unless one study their characters very carefully.
