In the Section Cyrtophlebium of Authors. 



A stout-fronded rare species^ well deserving a place in 

 every collection. The fronds are so thick that they will scarcely 

 bend without breaking. 



An evergreen stove Fern. 



Native of Tropical America. 



The fronds, which are contiguous and simple, are stipitate, 

 linear-lanceolate in form, having an attenuated base and a pointed 

 apex. 



The fronds, which grow erect, are in texture very thick, 

 coriaceous, smooth, and polished, having the margin thickened. 



Veins immersed, and difficult to see, darker than the frond, 

 and having club-shaped apices. Rachis almost buried within 

 the frond, perfectly flat above, and scarcely raised beneath.
