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 C. officinarum 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.
