Found growing in woods in Brazil. 



Introduced into the Koyal Gardens, Kew, in the year 1841 ; 

 having been received from the Royal Gardens of Berlin. 



Fronds glabrous, somewhat erect, pinnate, the pinnae being 

 lanceolate-acuminate in form, narrow, six to ten inches long; 

 membranous, decurrent at the base, and extending down the

For plants of this species I am indebted to M. Schott, Director 

 of the Royal Gardens of Schonbriinn, near Vienna; and to Mr. 

 Clarke, Curator of the Royal Gardens, Glasgow; and for fronds
