Trees, 10-35 m- tall and soTiietinies 75 cm in diameter. Leaves in 
clusters of three, surrounded by a rather chaffy and persistent sheath 
which is sometimes as much as 2 cm long but usually is much shorter. 
Leaves long, flaccid, compressed, 3-sided, with marginal resin-canals, 
18-^0 cm long, 0.6-1 mm broad. Male aments numerous, thick, dense, 
cylindraeeous, obtuse, 18-22 mm long, 3.5-4 mm broad; antheriferous 
bracts suborbicular ; antliers crested. Cones 2 or 3, verticillate, subter- 
minal, the younger ones oblong on erect branches, the adults on short 
horizontal branches or subpendulous, ovate, conical, obtusely straight or 
curved, short stalked, deflexed, 5-10 cm long, 3-G.o cm in diameter; 
falling when mature or persistent on the branches; cone-scales thick, 
with a tumid apophysis, which is broader than long, and an elliptic umbo. 
Meristele elliptic. Fibro-vascular bundle simple. Seed obovoid-conic 
with large wing which drops off as the seed dries. Wing clear, occasion- 
ally streaked or mottled with darker lines. Seed pale-straw-color or pur- 
plish, often of light color with splotches of brown or purple 5-7 mm 
long, 2.5-3 mm in greater and 1.5-2 mm in lesser diameter. Extreme 
length of wing 2 cm, extreme breadth of wing 8 mm. In order to get 
some idea of the range of variability in size and shape of cones, 115 adult 
cones from one locality in Benguet were measured. The length of these 
varied from 5 to 8.4 cm, the width (open) from 4 to G.2 cm. The 
shape varied from narrowly cylindric-conic to broadly o\oid-conic. Cbne 
scales occasionally with the apophysis prolonged forward into a more or 
less spiny point, or apophysis smooth in front. Umbo small, deciduous 
or sometimes persistent. The cones seem to take three years to mature. 
This pine shows a striking resemblance in habit to P. pontic rosa Pougl. 
of the western United States. 
The M'ood is used a <;oo<l deal locallv in northern Luzon. The resin 
has been studied as a possible conmiercial source of turpentine; but it 
tloes not seem i)romising, because of the scattered nature of the stand.
