A distinct new small species, remarkable by its very long stipe and small 

 lamina of coriaceous texture. It is related to D. laevigata, from which it differs 

 by its stramineous rachis and setulose costæ.

I am due to Dr. Rosenstock a specimen of this species unique by its peculiar 

 pubescence. Without a minute examination several of the hairs appear to be 

 stellate but the whole aspect of the species is that of Lastrea not of Goniopteris. 

 By microscopical analysis I found, however, that the hairs are not stellate, i. e. 

 branched, but fasciculate, as Dr. Rosenstock expresses it, i. e. 2 — 6 hairs spring 

 out from the same epidermal cell from nearly the same point.
