We are the more anxious to figure this species of Fern, because it has, by Dr. Sieber, been con- 

 founded with an East Indian species of the same genus, namely Acrostichum hybridum (Ic. Fil. 

 t. 21.) ; but from that it is distinguished by its much smaller size, more acuminated apex ; and espe- 



d 



l 



cially by the numerous reddish hairs, which spring not only from the margin, midrib, nerves, ai 



* 



stipes, but also from the whole superficies of the frond, both above and below, giving the entire 

 plant a very singular appearance. 



The Plumierian figure, which Dr. Swartz mentions with approbation, is by no means good as to 

 the marffin of the fronds and in the glabrous upper sides ; nor is the representation given by Lamarck 



at ali more satisfactorv.
