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 costa.

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.
