This very handsome Fern has its fronds glabrous, the sterile 

 ones pinnate, the pinnse being lanceolate-acuminate and some- 

 what membranous; the basal ones petiolate, with a wedge-shaped 

 base; the upper ones adnate at their inferior base, and decur- 

 rent. Habit reclining. 



The fertile fronds contracted, pinnate, the whole under side 

 of the frond being soriferous, except occasionally that two or 

 three of the lower pairs of pinnse will be sterile. 



Sori amorphous. 



Veins reticulated, and forming elongated areoles. 



Rhizoma erect and caudiciform. 



Length of frond from seventy to one hundred and twenty 

 inches; colour light green. 



As this Fern grows in morasses and vrater-courses, it is 

 necessary to supply it with abundance of water, placing the 

 pot in a pan of water, and potting with a mixture of turfy 

 loam and sand, and growing it in stove heat: by this means 

 a magnificent plant may be obtained. 



For a plant of this species I am indebted to M. Schott, 

 Director of the Imperial Gardens of Schonbriinn, Vienna; 

 and for fronds to the same gentleman, Mr. G. Norman, of 

 Hull, and Sir W. J. Hooker, Director of the Royal Botanic 

 Gardens, Kew. 



It may be procured of Messrs. Sim, of Foot's Cray; E. G. 

 Henderson, of Wentworth; and Booth, of Hamburg. 



The illustrations are from fronds sent me by Mr. Smith, 

 Curator of the Royal Gardens, Kew\
