This fern has gravitated back and forth between Phe- 
gopteris and Polypodium according to the views of different 
authors. Mettenius referred it to Aspidium, crediting it with 
the presence of a delicate fugacious indusium in its early 
states, but I have been unable to find any trace of an indusium 
in my own specimens, or any that I have examined, and 
some of them are of just the right age to show an indusium 
if any existed. Prof. Eaton referred it to Phegopteris, and 
it is true that it has the aspect of a Phegopteris, but no more 
so than some other Polypodiums with similar texture and 
pubescence. 
It is extremely doubtful if Fée would have admitted ferns 
with anastomosing venation, even though the veins in very 
young fronds were free, under Phegopteris, or that Pres! 
would have recognized under it his Goniopteris.
