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'a Asplenium fraxinifolium ia called " Di- 

 plazium fraxinifolium.'''' My impression ia 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 posseasing much 

 broader pinna?, great affinity with this ; but the whole group of 

 diplazioid Asplenia require a careful study and revision, which 

 we trust to attempt ere long.
