We concur with Mr. J. Smith in the propriety of restricting this 

 genus (so far as known) to the present species. Presl referred to it 

 the Asplenium Douglasii of Hooker and Greville, and also, but with 

 a doubt, the Allantodia Brunonis of Wallich : the former has the mar- 

 ginal veinlets free, while the indusium of the latter in a recent state 

 is cylindrical.
