Vatica,} DIPTEROCARPEZ. 253 
In the Flora of British India, Dipterocarpus levis is considered to be 
only a form of D. turbinatus ; this is almost certainly correct. As, how- 
ever, they were kept separate on account of their very different economic 
properties, by so careful and accurate an observer as Buchanan-Hamilton, 
and as no one has by actual observation in the field controverted his 
statements, it seems better here to leave the two trees as distinct species. 
In the Flora of British India, D. costatus is reduced to D. alatus, on the 
assumption that the figure of D. costatus given by Gaertner is bad. Asa 
matter of fact Gaertner’s figure is an an representation of one of 
the Garjans, and there is every reason to think that the species it repre- 
sents is also the tree which Roxburgh ROE by the name D. costatus. 
I cannot help thinking, however, that D. scaber bears to D. costatus much 
the relationship that D. levis bears to D. turbinatus, and that it is at 
most only a form of Gaertner’s tree. But here again no one is yet in a 
position to controvert the statements made by Buchanan-Hamilton ; this 
being so, the two trees are better treated, for the moment, as distinct. It 
iti 
may be able to record that the faaiety of these Garjans has been satis- 
factorily settled by some one resident in Chittagong. It is not a matter 
for Congratulation that we know less about trees so important as the 
Garjans than was known by English residents in Bengal 90 years ago.
