Hab. On the Corcovado, Rio Janeiro : in forests. Feejee Islands ; 

 at an altitude of 2,000 feet. 



Plant with a trunk one to 1£ feet high and from 10 to 15 inches 

 in diameter, to which the base of the old stipes remain attached, 

 crowned with from 8 to 12 erect fronds, which vary from 4 to 7 feet 

 in length, and are of a paler colour on the under than upper surface. 



We were not a little astonished and delighted on detecting, in the 

 mountain forests of the Feejee Islands, this Fern, which we had pre- 

 viously found in Brazil, and supposed to be indigenous to the latter 

 country only. The plants from both countries are identically the 

 same, with the slight difference, that the Feejee plant is somewhat 

 the smaller of the two.
