A tall tree with rich green foliage, growing on a strip of coast south of San Francisco, particularly in Monterey County. It grows also on the islands forming the Santa Barbara Channel and on the Island of Guadeloupe, Lower California. It is remarkably successful in the warmer climates of Europe and of Australasia. The species is distinct in its peculiar cone with rounded apophyses.

XIII. MACROCARPAE
Pits of the ray-cells small. Wing-blade of the seed thick. Cones large. Leaves long and stout.
This group is remarkable for the size of leaf, conelet, and cone. The peculiar thick seed-wing is more or less obscurely present among the species of the Insignes, but never attains the development that differentiates this group from all other Pines. The leaf-section is notable for the large amount of hypoderm and for the presence of both thick and thin outer walls of the endoderm-cells, both forms appearing in the same leaf.
