PHILIPPINE DIPTEROCARPACEAE. 
277 
cm wide. Petiole 1 to 2 cm long. Secondary nerves 14 to 22 pairs, 
arching ; tertiary parallel, prominent. Plowers sessile, in seennd bracteate 
spikes; each flower subtended by two unequal bracts. Ovary pubescent, 
narrowed into a glabrous filiform style, much longer than ovary ; stigma 
minute. Fruiting calyx with 3 wings 9 to 12.5 cm long, 15 mm wide, 
narrowed below, but base dilated, tightly enclosing the fruit; transverse 
veins and 7 to 9 longitudinal veins prominent. 
Fruits abundantly in August, but the fruit is quickly eaten by wild 
hogs, etc., perhaps for contained fat, and in a very few days, it is difficult 
to find any of the seeds remaining. 
The resin is sometimes collected from the tree for torches, etc., although, 
I think, not on a commercial scale. The timber is used in great quanti- 
ties under the name of almon.
