Near Blechnum inelanopum (HooK. Sp. Fil. III. p. 64 t. CLXL) ; but 

 slightly different from it in having less anastomosing veins. In appearance, 

 the present species is very like sterile fronds of Playiogyria faleata which 

 grow 011 rocks with the new fern.

Very near Polypodium angustissimwrn BAKER. Undoubtedly our plant 

 belongs to the same section with that species.
