31Q FILICES. 



Hooker and Greville, in their Icones Filicum, have figured a state 

 of this from the Mauritius, with which our plant from the Samoan 

 Islands agrees. In the Brazilian plant the substance of the frond is 

 of a firmer texture, less cordate at the base, and the point more 

 acute than in the Samoan one ; but the relative length of the scape 

 and frond, and the other characters, entirely correspond with the 

 figure to which we have referred.

 Feejee Islands ; on trees. 



The figure of this species in Hooker and Greville's Icones Filicum, 

 exhibits a spike which, for length, far exceeds any we have ever 

 seen : on the other hand, among our specimens from the Samoan 

 Islands, there are individuals whose fronds measure over 4 feet in 

 length : the shortest ones in our possession, were gathered at the 

 Sandwich Islands ; and a considerable number of them are simple and 

 falcate in form ; these are probably of the var. " (3. Fronde falcata," 

 of Hooker and Greville. This latter form occurs only on elevated 

 situations, where the plant is exposed to the light and a strong 

 current of air.
