We are indebted for our beautiful specimens of this little-known Fern to M. Bojer of the Mau- 

 ritius, who took it for a Tanitis, and marked it Tcenitis simplicifolia of his MSS. We think, how- 



1 



ever, that there is no doubt of its being the Grammitis lanceolata of Swartz : but it must be allowed 

 that the fructification, especially in the upper part of the frond, has a good deal the appearance of 

 that of a Tcenitis. 



Schkuhr (t. 7.) mistook a West Indian Fern (the Grammitis elongata of Sw. and Willd.) for this 





of the Mauritius ; but that diifers from our pla 



much smaller size, more rigid 



the presence of numerous stellated scales, and in the sori of fructification being short, uniform, and 

 forming a regular series or single line between the margin and the midrib.
