INTRODUCTION. 
T HE present paper is the outcome of about two and a half years’ work 
on the vegetation of the area defined below. At first the work 
was confined to a systematic investigation of the flora, but since we have 
become fairly familiar with the common species we have attempted a 
preliminary study of the oecology of the district. We are fully aware 
that the latter is, at present, ity many ways, very far from complete, but 
we hope that on some future occasion it may be possible to fill in some 
of the gaps. For instance, no study has yet been made of the water 
content of the soil in the different associations, nor has the question of 
anatomy in relation to function (physiological anatomy) been touched. 
We are glad to take this opportunity * of expressing our thanks to 
the Director, Royal Gardens, Kew, and to the Director of the 
Botanical Survey of India, for kindly sending us determinations of a 
number of species which we had submitted to them for this purpose, 
nearly all of which are ^o noted below as “ Determined at Kew ”, 
and "Determined at Calcutta”, respectively. We have referred our 
specimens to one or other of these authorities whenever we had reason 
to consider that any doubt existed as to the correctness of our own 
determinations. 
We have also referred a good many specimens to Mr. R. K. BHinnof 
the Poona Herbarium, whose opinions have always been of value, and 
to whom also we desire to express our thanks.
