 bulb. Sterile frond simple, entire, oblong or ovate-lanceolate;

My thanks are due to Mr. James Yeitch, of the Exotic 

 Nursery, Chelsea, for a plant and fronds of this Fern. 



Introduced into England about two years ago by Mr. Veitch, 

 of Chelsea. 



It may be procured of Messrs. Veitch, of Chelsea; Sim, of 

 Foot's Cray; E. G. Henderson, of St. John's Wood; and Rollis- 

 son, of Tooting. 



The illustration is from a plant in my own collection.
