OF THE DIPTEROCARPACEZ. 33: 
Blade 7-9 in. long; fruit 1 in.; wings 4-5 in. long, 1 in. broad. 
Differs from Dipterocarpus cornutus by the glabrous leaves and the 
narrow neck above the fruit, formed by theshort calyx-tube. Vidal 
(‘ Sinopsis, plate 14 C) represents a fruit somewhat resembling 
this species. It is called there D. turbinatus, and is said to have 
been brought from the island of Ilo-Ilo (Panay), which is situated 
halfway between the main portion of Luzon and Mindanao. The 
fruit of .D. turbinatus from the Andamans and Malaeca is also 
constricted at the apex, but it is more globular than the elongated 
fruit of this species, which, moreover, has 5 protuberances alter- 
nating with the segments of the fruiting-calyx.
