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. Plate XXXVII. Figs. 319, 320, Cones. Fig. 321, Leaf-fascicle and magnified leaf-section.

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. Wing-blade with a short membranous extension. Leaves in fascicles of 5 64. Torreyana Leaves in fascicles of 3 65. Sabiniana Wing-blade with a long membranous extension, leaves in fascicles of 3 66. Coulteri 64. PINUS TORREYANA 1855 P. Torreyana Parry ex Carrière, Trait. Conif. 326. 1860 P. lophosperma Lindley in Gard. Chron. 46. Spring-shoots uninodal, pruinose. Leaves in fascicles of 5, from 20 to 33 cm. long, very stout; resin-ducts medial, hypoderm uniform or somewhat multiform and of many cells. Conelets large, mucronate. Cones from 10 to 15 cm. long, on stout peduncles, broad-ovate, symmetrical, somewhat persistent; apophyses chocolate-brown, prominently pyramidal, the umbo salient and capped with a small mucro; seed-wing short, very thick, the dorsal surface of the nut spotted with the black remnants of the spermoderm. A tree 10 or 12 metres high, often semi-prostrate in exposed positions, confined to a restricted area on the coast north of San Diego, California, and to the Island of Santa Rosa. This species resembles P. Sabiniana in the length of its seed-wing and in the color of its cone, but is distinct in the short triangular umbo, in its pentamerous leaf-fascicles and in the mottled dorsal surface of its nut.
