_ Since the publication of the first volume of the ‘Flora 
of British India” in 1873, very large collections of 
Himalayan species of Impatiens have been received at 
Kew, which, together with those of the Herbaria of the 
Calcutta and Saharunpore Gardens, kindly lent by Messrs. 
Prain and Duthie, will, I hope, enable me to revise the 
species (124) published in that work, introducing some 
new ones, and correcting the characters and synonymy of 
others. Unfortunately the plants of this genus wither so 
rapidly after being gathered, and suffer so greatly from _ 
the pressure in transformation into Herbarium specimen 
that a great many examples in all herbaria are quit 
insufficient for correct determination. Furthermore, fruit- 
ing specimens are essential, and it is only from living 
ones, or carefully executed drawings, that dependable 4 
characters can be obtained. J
