12 GYMNOGRAMMA SULPHUREA. 



The sori, which are linear, are forked obliquely, becoming, 

 when fully mature, confluent and nearly covering the whole 

 frond. 



Mr. Henderson, of Wentworth, has kindly communicated 

 plants and fronds of this species. I am also indebted to Messrs. 

 Booth and Son, of the Flottbecker Nursery, Hamburgh, for 

 others, and to Mr. Norman, of Hull, for fronds. 



G. sulphurea is not common in cultivation; it is in the Fern 

 catalogues of Messrs. A. Henderson, of Pine-apple Place; 

 Backhouse, of York; and Booth and Son, of Hamburgh. 



This species requires more washed sand to be mixed with 

 the soil than most other Ferns, plenty of drainage, and it must 

 not be allowed to become too dry. 



The illustration is from a frond kindly communicated by Mr. 

 Henderson, of Wentworth.
