Dear Prof. Merrill, 
Enquiries regarding lack of data on the Herbarium 
sheets supplied to you show that only the names were put 
down on the sheets due to hurry. The data, as suggested 
in your pamphlet are all in the field books. I am 
supplying a list of the specimens with the data as far 
as could be traced from the field numbers. If you will 
kindly send me- the field numbers of the rest of the sheets 
with the specific names^I would then furnish you with the 
data of these too as far as possible. The collections 
sent to you are from two localities which are important 
from the standpoint of distribution of Indian flora. They 
were all collected by me during tvro botanical explora¬ 
tions, one along the borders of Nepal and West Sikkim 
from an elevation of 6000 ft. to 13000 ft., in the 
Eastern Himalayas extending over fifty miles from Darjee¬ 
ling. The other species were collected from Northern 
Bengal to the borders of Bhutan at a height of 6000 ft. 
The booklet supplied to me was published in the 
Arnold Arboretum^and I am pleased to have a copy for 
myself. It is indeed a very good guide and botanical 
explorers
