OBS. The general appearance of this species seems to indi- 

 cate its affinity to be with C, officinarum rather than with any 

 species of Gymnogramma, differing only from G. ojficinarum in 

 the veins being generally free, rarely anastomosing.

OBS. With regard to L. reniformis, L. sagittata, L. 

 Leprieusii, L. falcata, L. trapeziformis, L. stricta, L. crenata, 

 and L. dubia, entered at p. 230, it is proper to state that they 

 were entered on the evidence of living specimens sent to me 

 from Mr. Backhouse, of York, who had recently imported 

 them from their native country, and I expected that they 

 would soon have been added to the Kew Collection ; but they 

 proved to be of difficult cultivation ; and Mr. Backhouse writes 

 me that he has not succeeded in establishing any of them. 

 This is much to be regretted, as Lindscea is a very interesting 

 genus of Ferns.
