Hab. Martinique, Plumier. West Indies and tropical S. America, probably 

 universal, on the authority of almost all collectors and botanical travellers. I 

 must confine myself in regard to localities principally to such as, in my herbarium, 

 bear numbers Avbich have been distributed with specimens, and which are so far 

 authority for what I would refer to this species. West Indies: Cuba, Linden, n.

 thority for the species being the very exaggerated figure of Plumier. I have done 

 my best to bring correct synonyms under it, and really, making allowance for va- 

 riations which are common to Ferns in general, it is a species as readily distin- 

 guished as almost any of the genus. Raddi's figures are emiuently characteristic.

 costa but not extending to the margin, 3-5 sori in the auricle.
