The Polypodium incisum of Swartz, appears, as far as we can judge from the description, to be a 

 species very nearly aliied to this ; and Linnaeus is himself said to have confounded the two ; the 

 P. scolopendrioides of the first edition of Sp. PL being now considered as the P. incisum, and 

 that of the last edition our true plant. Swartz tells us that the P. scolopendrioides has the smaller, 

 but broader, fronds, and that the lower segments or divisions are remote from each other, so as to 

 be there pinnate, as in Plukenefs figure. But the same author equally refers to Plumier's plant, 

 which exactly, in this respect, resembles our own, having those segments coadunate. 



In this Fern the cuticle or epidermis is easily removed by the aid of a dissecting knife ; and then 

 the nerves are rendered distinctly visible, with the dots or scars whence the sori have proceeded ; 



as shown at fig. 1 . of our plate. 



We are indebted to A. B. Lambert, Esq. for our specimens, who received them from Mr. Wiles 



of Jamaica.
