XIPHOPTERIS SERRULATA (GRAMMITIS.) 

 Kaulfuss. 



2Ciphopteris — From the Greek, Sword Fern. Serrulata — Saw-edged. 



A MOST singular little Fern; rare in cultivation. 



An evergreen stove species. 



Native of the West Indies, and imported from Jamaica. 



The barren and fertile fronds different, the latter longer, 

 and the apices, which alone are fertile, a little flattened out 

 in breadth; the soriferous part of the fertile frond minute. 



Rhizoma tufted, spreading by its filiform stolons, by which 

 means it is increased. 



Length of sterile frond one inch and a half; of fertile 

 frond three inches; width one sixteenth of an inch. 



For fronds my thanks are due to Mr. R. Sim, of Foot's Cray^ 

 Kent.
