Il]. Tor DirpTEROCARPUS-SHOREA FORMATION. 
On the south side of the Reserve there is a characteristic type of 
vegetation between the two hundred and fiftieth and four hundred and 
fifth meter contour lines; on the north, as shown by the map, the type 
almost entirely disappears. Over 15 per: cent of the trees belong to 
one species, Dipterocarpus grandiflorus (apitong). So characteristic is 
this species that it was thought advisable to separate the forest where it 
is encountered into a distinct formation, giving it the name of the two 
principal species of Dipterocarpacee which are found there. (Pls. XXIV 
and XXVIII.)
