Alsophila — From alsos, a grove, and philos, to live, alluding 

 to the habitat of the Ferns. Ferox — Fierce, in reference to the thorny 



character of the plant. 



A coarse-looking, large-growing, though elegant Fern, re- 

 markable for lengthy sharp thorns, with which it is abundantly 

 provided. 



An evergreen stove species. 



Native of South America and West Indies, Jamaica, Brazil, 

 Bahia, Surinam, Guiana, Cayenne, and Trinidad. 



The fronds, which are glabrous, are broadly lanceolate in 

 form, bipinnate, with sessile, linear-lanceolate, rather membranous, 

 profoundly pinnatifid pinnules, and linear-oblong, somewhat fal- 

 cate segments, with a serrated margin.
