Hooker and Greville, in the Icones Filicum, have very accurately 

 characterized this Fern as a genus distinct from Dicksonia and Oibo- 

 tium. Kaulfuss, who first described the species, placed it in the 

 former genus; to which it certainly claims a stronger affinity than 

 to Cibotium, where Presl referred it. In a few instances we have 

 found the sori on the back of a venule, near its point, when the 

 indusium is oblique and subcylindrical ; but the more usual state of 

 the plant, as regards the form of the indusium and the position of 

 the sori, is that represented in the Icones Filicum.

The figure cited is an excellent representation of our form of this 

 species.
