In size and texture this pretty Grammitis resembles the 
G. leptophylla of Swartz, but the pinne and pinnules have 
nothing of the broad and cuncate form of that species. In 
ramification it more nearly approaches the Gymnogramme 
cherophylla, but that species is much larger, and the ultimate 
segments are longer and narrower and almost acute, and the 
fructifications are more copious and continuous. The present 
Plant is, as far as I know, wholly confined to the Island of 
Ascension.
