This fine Fern has been largely distributed by the late 
Dr. Wallich, under the name of Asplenium (Diplazium) 
fraxinifolium ; and I am desirous of making it known to the 
botanical world ; for as far as I am aware, it has been noticed 
by no Fern-author in any way, save that, in Moore’s Index 
Filicum, Wallich’s Asplenium fraxinifolium is called Di- 
plazium fraxinifolium.'^^ My impression is that this Fern, 
with its free venation will prove specifically identical with 
Diplazium (Oxygonium) elegans, figured in Hook. Ic. PI. t. 
939-940, notwithstanding the anastomosing venation of the 
latter. I would observe, too, that the Diplazium alter nifolium^ 
Bl. (and Hook. Fil.Exot. Tab. 17) has, though possessing much 
broader pinnae, great affinity with this ; but the whole group of 
diplazioid Asplenia require a careful study and revision, which 
we trust to attempt ere long.
