2 PTERIS DENTICULATA. 



A DELICATE species, rather difficult to manage, and requiring- 

 a hot-house for its cultivation. 



An evergreen stove Fern. 



Native of Brazil. 



Introduced into England in 1824. 



The fronds, which are triangular in form, are glabrous, the 

 basal branches sub-pinnate, with the inferior segments bipartite, 

 above pinnate, with the inferior segments divided. 



Fronds oblong, acuminate, and decurrent at the base; mar- 

 gin serrate, with spinulose teeth. Terminal, and adherent to 

 a fasciculate rhizoma. 



Sterile fronds broader than the fertile fronds; fertile fronds 

 erect, and rising above the sterile fronds. 



Sori linear and continuous. 



Length of frond from twelve to eighteen inches. 



For plants my thanks are due to Sir Oswald Mosley, Bart., 

 of Rolleston Hall, near Burton-on-Trent. 



It may be procured of Messrs. Yeitch, of Chelsea; Booth, 

 of Hamburg; Sim, of Foot's Cray; A. Henderson, of Pine-apple 

 Place; E. G. Henderson, of St. John's Wood; and Kollisson,
