INTRODUCTION. 
THE paper which I have now the honour of laying before you is the result of my 
botanical investigations and collections made while I was attached to the Afghan 
Delimitation Commission during the years 1884 and 1885. 
My collections amount to about 800 species and some 10,000 specimens. Of these nearly 
one hundred are probably * new to science, and, as may be seen from this Report, I have | 
been able to accumulate much interesting matter in relation to products, and to trace 
several to the plants yielding them. Тһе difficulties I have had to overcome in obtaining 
the material for the information I now lay before you were on this occasion very great. 
I purpose dividing my paper so as to give the botanical characteristics of the country 
traversed in accordance with its natural divisions represented by its physieal features, 
viz. :—Northern Baluchistan ; the valley of the Helmand, from Hadj-ali to the Hamun; 
the basin of the Harut river, from the Hamun of the Helmand to Pahir ; the valley of 
the Hari-rud; the Badghis district; Mount Do-shakh ; and Khorasan. 
* I say probably, because, in consequence of expecting to have to return to India, the collection has been 
hurriedly and only partially elaborated.
