A tree 80-100 feet in height, with a trunk 2-3 feet in diameter ; 

 sandy soil in immediate proximity to the sea-coast ; rare and local ; 

 now widely cultivated on the Pacific coast for shelter and ornament. 

 A form from Guadaloupe Island, off the coast of Lower California, 

 with leaves in pairs, is var. binata (Engelm. in Proc. Am. Acad. xi. 

 119, and Bot. Calif, ii. 128). 



P. insignis, Dougl., is distinguished by its fresh green foliage and 

 closely and strongly serrulate leaves. Cones generally thick and very 

 oblique, with the scales of the outer side large paid thick, and on the 

 inner side smaller and flat ; some cones are more regular, all the scales 

 being nearly equally flat. 



A young plant, somewhat covered in the winter time, has kept alive 

 three years. Another not well covered died.

A large tree 98-100 feet in height, with a trunk 4-13 feet in 

 diameter ; dry, gravelly slopes between 6,000 and 8,000 feet eleva- 

 tion ; most common, and reaching its greatest development, on the 

 eastern slope of the Sierra Nevadas, here generally replacing the allied 

 P. ponderosa, from which it may be distinguished by its more deeply 

 cleft bark, glaucous branclilets and leaves, much larger cones, and by 

 the strong pungent odour of oil of orange of the freshly cut branclilets. 



Wood light, strong, hard, rather coarse-grained, compact ; bands of 

 small summer cells not broad, very resinous, conspicuous ; resin 

 passages few, not large ; medullary rays numerous, obscure ; colour 

 light red, the sapwood pale yellowy or nearly white ; specific gravity,
