The present Polypodiwum comes near P. Engleri, but differs 
from it in the veinlets spreading from the midrib in a much 
acuter angle. Also near J. arenarium Baker and P. Schritt- 
plinianum Axnir, but differs from the former in having broader 
fronds which are much acuter on both ends, and in the sori which 
are limited on the upper parts of the fronds, and from the latter, in 
having acuter and larger fronds of a different texture.
