very unlike some > of Hymenophyllum or Trichomanes 
resl’s figure in the k 
is singularly long, slender, and creeping. In both those works 
the affinity of the species with A faniculaceum, H. B. K. 
(Hook. et Grev. Ic. Fil. +. 92), is noticed, and we ourselves 
owever, is naked and wiry; in A. feniculaceum tomentose. 
may vary, perhaps, according to situation and moisture. 
Pceppig’s specimens, and those of Mr. Mathews, both in our 
possession, show no disposition to vary from the form here 
represented. Some of the specimens are indeed smaller, but 
none oe It may be referred to the Darea or Cenopteris 
group of Asplenium, having the segments and lobes so narrow 
as rarely to bear more than one sorus on each.
