10 GYMNOGRAMMA OCHRACEA. 



more scantily supplied with hairs than is the case either M'ith 

 G. calomelanos or G. tartarea. The young unfolded frond 

 is of a darker green than in either of the before-mentioned 

 species, and it is more thickly covered with the yellow farina. 



The form of the frond of G. ochracea before it is unfolded, 

 is very different to the other Gymnogrammas , for it is con- 

 vex, and only immediately below the apex concave with respect 

 to the rhizoma; whilst in the other three species before described 

 it is concave. 



The sori are medial, being somewhat scattered on the veins. 



It is very readily propagated from spores. 



A similar treatment in the cultivation of this Fern to that 

 adopted with G. cJirysophylla will be found to answer remark- 

 ably well; indeed it seems less delicate than any of the Ferns 

 yet described. 



This tolerably abundant species is to be found in the cata- 

 logues of Messrs. Rollisson, of Tooting; Henderson, of Pine- 

 apple Place; and Backhouse, of York. 



The illustration is from a plant in my own collection. 



Fronds for examination have been kindly forwarded by Mr. 

 Henderson, of Wentworth; Mr. Ingram, of the Royal Gardens, 

 Windsor; and Mr. E. Cooling, Nurseryman, Derby.
