lO.—Species of the Burmese Be^ion, from Assam to Tenasserim. 
The Balsams of this region are very imperfectly known. Except 
in the Khasia and adjacent Hills no satisfactory collections have been 
made over the vast area limited as above. Sixteen species were 
obtained by Wallich and his collectors between 1820 and 1830 
from various localities between Assam and Tenasserim, to which a 
considerable number were added by Griffith in the Khasia Hills 
in 1835 and 1837, Twenty species were collected by Dr. Thomson 
and myself also in the Khasia and neighbouring hills in 1850 ; since 
which period Mr. C. B. Clarke going over the same ground, and 
extending his travels to the Naga and Manipur Hills, has added 
considerably to this number. Other contributors have been theRevd. 
C. Parish in the Maulmain mountains, and collectors employed by 
the Royal Botanic Gardens of Calcutta in the Shan and other Hills 
east of the Irawaddi, but discoveries of the latter have been for the 
most part units. Mr, C. B. Clarke is the only one who has made 
notes of many species on the spot where found, and these are of 
great value. 
Judging from the reports of Forest Officers and travellers and 
having regard to the nature of the hill and mountain ranges of 
Burma it cannot be doubted that this country is exceedingly rich in 
Balsams, and when it is considered how few species have been obtained 
from the 1,500 miles of complicated lofty ranges on the east of the 
Salwin river, and that not a single species has as yet been obtained 
from the 500 miles of lofty coast range extending from Chittagong to 
Cape Negrais, it seems to be impossible to regard the 52 species 
here enumerated below as giving even a remote idea of the richness 
of the Balsam Flora of Burma, which is further emphasised by the 
heterogeneous character of its components. In evidence ©f the 
truth of this last observation it is sufficient to point out, that in my 
attempt to group the species under natural sections I have had to 
adopt 16 of these; which is 7 more than were required for the 63
