REPORT 
ON 
A BOTANICAL TOUR IN THE LAKHiMPUR 
DISTRICT OF ASSAM. 
1 894. 
This tour was undertaken and accomplished during the months 
of March and April 1894. 
Although at this season of the year the bulk of the herbaceous 
vegetation is either dormant or has not yet appeared, still from the 
similarity of the Flora to that of the Sub-Himalayan tracts to the 
westward, I was able to identify many plants from long and intimate 
acquaintance with their general appearance. 
A representative collection of specimens w’as made, chiefly 
from trees and shrubs in flower or fruit, which has afforded me a 
good insight into the composition of the woody vegetation, and 
while engaged in determining my plants in the Calcutta Herbarium, 
I often found it possible to correlate materials obtained by former 
collectors. Of these. the first were Dr. Wallich and Dr. Griffith who 
were deputed by Government, in 1834, to examine the tract of 
country producing the indigenous tea plant. The latter botanist 
has left on record (in the I'ransactions of the Agricultural and Horti- 
cultural Society of India, Volume V, 1838) a valuable systematic list 
of plants collected in the neighbourhood of Sadiya in which he em- 
phasizes the strong affinities of this Flora with that of China, 
Of more recent collections the chief have been those formed by 
Mr. Gustav Mann, late Conservator of Forests in Assam, and Mr. C. 
B. Clarke. Both have devoted much of their leisure time and atten- 
tion to the Flora of this province greatly to the advantage of Botani- 
cal Science. Thanks to the labours of these and other botanists and 
collectors, little of novelty can now remain undiscovered in the valley, 
but the surrounding mountains must yield rich harvests to naturalists 
in the future. 
Joining the daily despatch steamer at Jatrapur I went direct to 
Dibrugarh, the chief town in Lakhimpur. This rapid voyage up the
