Hab. Vicinity of Rio Janeiro, Brazil : on the trunks of trees. 



Raddi quotes LangsdorfT s figure of this, under his Polypodium 

 vacciniifolium; yet, judging from his own figure and description, we 

 are inclined to believe that his plant may be a different species, or a 

 very decided variety of the present one; the sterile fronds being 

 ovate-lanceolate or oblong-lanceolate. May not Raddi's plant be the 

 Polypodium ciliatum of Willdenow ?

Hab. Andes of Peru : on rocks. 



Closely related to the preceding; but quite distinct in the thicker 

 rootstock, the larger and less coriaceous fronds, and the more remote 

 and ascending segments, which are naked on the upper and less scaly 

 on the under surface.
