32 ASPLENIUM PLANICAULE. 



which are triangularly-elongate; bipinnate, pinnules remote; those 

 pinnse at the base longest, becoming shorter as they approach 

 the apex of the frond, being in fact oblong cuneate, each pin- 

 nule is also of an oblong wedge-shaped form, with an acute 

 apex, the one nearest the rachis being largest. Decurrent at 

 the base, and serrate on the margin. 



Stipes and rachis dark-coloured beneath, and green above; 

 rachis winged. The fronds terminal, rising out of a somewhat 

 tufted rhizoma. 



Length of frond from one foot to eighteen inches, more fre- 

 quently the former; colour of frond deep green. 



The fructification is prettily arranged, but not very bold in 

 appearance. 



It appears to be better known under the name Asplenium 

 Mexicanum of Kunze, than that of A. planicaule of Wallich.
