THE FERNS OF NORTHERN INDIA. 409 
Kew, to publish a note of the new and critical plants ; because, if 
no record is thus kept, when the selected specimens have been 
once sorted into their places in the Kew herbarium, it is practi- 
cally impossible to collect them again. 
We have therefore drawn up the present Note, which is in the 
form of a supplement to the paper of C. B. Clarke, “On the 
Ferns of Northern India,” published in the ‘ Transactions’ of this 
Society, series 2, Botany, vol. i. pp. 425-611. 
The collection of C. B. Clarke included some ferns authenticated 
by H. Blanford; and among these some species lately printed 
in H. Blanford’s ‘ Simla Cheilanthes ': and there are a few miscel- 
laneous observations noted by J. G. Baker referring to North- 
Indian Ferns, but not exactly suggested by the collection of 
C. B. Clarke.
