PLATYLOMA BROWNII. 



Sori continuous along the whole margins, forming a very 

 broad band; the indusium, which is of that nature which is 

 called spurious, very narrow, not covering the spore-cases, and 

 consisting of the revolute attenuated margin. 



Length of frond from one to two feet: colour above dark 

 green, below paler. 



Rhizoma creeping subterraneously. 



A plant of easy culture with ordinary management. 



The fronds are nearly erect. 



For a plant of this species I am indebted to Messrs. E. G. 

 Henderson, of the Wellington Nursery, St. John's Wood; and 

 for fronds to Messrs. Rollisson, of Tooting; and Mr. Joseph 

 Henderson, of Wentworth; and for valuable information regard- 

 in°- this Fern to Mr. Moore, the able Curator of the Chelsea 

 Botanic Gardens. 



It is in the Catalogues of Messrs. Sim, of Foot's Cray; 

 A. Henderson, of Pine-apple Place; Parker, of Hollo way; E. 

 G. Henderson, of St. John's Wood; Stansfield, of Todmorden; 

 and Rollisson, of Tooting. 



The illustrations are from fronds off the plant in my own 

 collection. 



Barren Frond.
