The natural affinity of this plant is with the Pleopeltis 
ensifolia Carm. (Hook. Exot. Bot. 1. 62). and still more with 
Pleopeltis nuda, Hook. Exot. Bot. 1. 63, now generally placed 
in Drynaria (Phymatodes). {Lepisorus, J. Sm., and we believe 
that the venation of these will be found sufficiently to corres- 
pond : specifically, however, our present plant differs, not only 
in the great length of the fronds and the marginal situation 
of the sori, but further in the shape of the sori, approaching 
receptacle of the sorus being in reality linear. In that 
groupe I would willingly have ranked it, but that I know of 
structure with the view to the future consideration of genera, 
than hastily to form a new genus, which, on further in- 
vestigation, may be found unsound,
