Of GrABDENS. 



Affine — Related. 



A Fern scarcely known amongst cultivators. 



A greenhouse species. 



Galliotti found it on the Volcano Orizaba, at an elevation of 

 from nine to ten thousand feet, growing in oak and fir woods. 

 Leibmann found it in the woods over Chinantha, between seven 

 and eight hundred feet high, principally growing upon the oak 

 trees. 



A very characteristic fact which authors do not speak of, and 

 which is especially of importance in relation to this species, is 

 the rhizoma. 



Pinnate, with three to five pairs of inch-wide divisions, with 

 a terminal one. The divisions profoundly dentate.
