Near P. solidum METT., but differs from it by the thinner herbacaous 

 texture, bluntly lobed pinnae, and hirsute fronds and venis; also near P. cucullatum 

 and P. trichomanoides, but separable from tham by the dentataly lobad pinnae ; 

 still nearer Polypoditim glandidosum (HooK. Sp. Fil. IV. p. 193, t. 276), from 

 which our plant is distinguishable in having much narrower and much remotar 

 pinnae of very much thinner texture, and by the absence of glandular hairs.
