Frondibus elongatis lineari-lanceolatis acuminatis marginibus 
revolutis inferne in stipitem brevem attenuatis subcoriaceis

liberis divaricatis apice clavatis, soris marginalibus oblongis 
seriatim dispositis contiguis immersis, capsulis longe stipitatis 
squamulis stipitatis immixtis, caudice repent e squamoso.

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 
to oval indeed in Pleop. nuda , here invariably oblong, so as 
properly to belong to the tribe Grammitacece of Presl, the 
receptacle of the sorus being in reality linear. In that 
groupe I would willingly have ranked it, but that I know of 
no genus there in which it could with propriety be placed, 
especially if the venation is considered. The difficulty would 
be readily solved with some botanists, by making a new genus 
of it ; but we think it of much more importance to illustrate 
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.
