Closely allied in general appearance to Polypodium cuspi- 
dijlorum * of Reinwardt, of which we have authentic specimens 
in our possession from Java, and from Luzon, gathered by 
Cuming ( n . 109.) This latter is, however, a much smaller 
plant, very opaque, with no visible costulae ; the fronds have a 
broader base, more suddenly tapering into a beak, almost 
quite sessile, upon an exceedingly slender, filiform caudex, 
destitute of scales, but throwing out copious woolly fibres. 
The venation of our present species is seen with difficulty, 
being quite sunk in the very opaque frond, but from what 
I do see of it, I should judge I am correct in referring it to 
Drynaria , Presl. M. Fee, however, places it in the genus 
Craspedaria , Link, which corresponds with the first section of 
Presl’ s Marginaria 5 though I suspect the venation is very 
different.

A species nowhere described as far as I can find.
