PHILIPPINE DIPTEROCARPACEAE. 277 
em wide. Petiole 1 to 3 cm long. Secondary nerves 14 to 22 pairs, 
arching ; tertiary parallel, prominent. Flowers sessile, in secund bractcate 
spikes, each flower subtended by two unequal bracts. 0\ai7 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 Augiist, 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 n commercial scale. The timl)er is used in great quanti- 
ties under the name of almon.
