Very large trees, up to 50-60 m in height and more than 2 in. diame- 
ter, with a clear length, sometimes, of as much as 30 m. This is easily 
the largest tree in the Islands. It occurs gregariously in the mountain 
forests at elevations of from 200 to 2,000 m, attaining its best develop- 
ment in the Philippines on well-drained slopes at 600-1,500 in. 
The bark is rather smooth, of a grayish color, 1-1.5 cm thick and 
contains numerous longitudinal resin-cavities. Resin collects on the sur- 
face of fresh eu,ts, and hard resin is found in masses wherever there is 
an old wound on the tree, often in the forks of the lowermost branches 
and sometimes also in the roots and the ground at the base of the tree. 
This resin is collected and exported as the Manila copal of commerce. 
Leaves thickly coriaceous, of the same color on both surfaces, light- 
green, without distinct midrib, elliptic, oblong, or lanceolate, usually 
rounded or obtuse at apex, but sometimes even acute 1 , narrowed abruptly 
below into a short petiole, with numerous fine, parallel, longitudinal 
veins; 3-10 cm long or even longer on seedlings or young shoots, 1-1 
cm wide or less than 1 cm wide on old or fruiting branches. On seed- 
lings and young shoots the leaves are often distinctly lanceolate, some- 
times acute at apex and relatively quite large ; on old branches or fruiting 
branches the leaves are much smaller and are often elliptic or oblong and 
distinctly obtuse or rounded at the apex. There is a great range of 
variation and all intermediate forms are found between the two extremes 
noted. The staminate flower-clusters are more or less elliptic-oblong, of 
various size, up to 4-5 cm long and 1-1.5 cm in diameter, and are borne 
in the axils of the leaves. The pistillate flowers are in ellipsoid-globose 
cones which are borne on short stout branches. The cones take 2 years 
to come to maturity. They are often of a purplish color and may be 
as much as 4—5 cm in diameter during their first year, reaching a 
diameter of 10 cm or more when mature. The seeds may be found 
with or without wings.
