No. 188. 
So many species of Vittaria have been inadequately described that it is 
difficult to be certain that any apparently new form is not one of them. 
In Euvittaria it would be possible to identify this plant satisfactorily; but 
it is unmistakably and obviously a Taeniopsis, and in this group its broad 
base is in itself diagnostic.
