A tree attaining in the Philippine Islands a height of 80 feet. 

 Buds about inch long, cylindric, covered with chestnut-brown 

 linear-lanceolate scales. Leaves crowded on the branchlets, in threes, 

 slender, 6 to 8 inches long, serrulate, ending in a cartilaginous 

 point ; sheaths persistent, | inch long or more at first, but soon 

 becoming torn or lacerate. 



Cones in twos or threes, erect when young, horizontal or slightly 

 pendulous when mature, ovoid-conic, about 2 to 3 inches long ; 

 apophysis of each scale rhomboid with a transversely keeled umbo.

 it occurs in Northern Luzon on exposed dry ridges at over 5,000 

 feet elevation. It has not been introduced into cultivation. 



The specimen figured was obtained from Mount Tapula, in the 

 province of Zambales, Luzon, by Messrs. M. L. Merrill and M.
