Habitat. — Staten Island, New York, south to the Chattahoochee 

 region of Western Florida, through the Gulf States to Tennessee and 

 Eastern Texas, and through Arkansas to the Indian Territory, 

 South-eastern Kansas, Southern Missouri, and in Union County, 

 Illinois. 



A tree 80-100 feet in height, with a trunk 2-5 feet in diameter ; 

 light sandy soil, or, less commonly, along the low borders of swamps, 

 forming west of the Mississippi Biver, mixed with Oaks and other 

 deciduous trees, extensive forests ; the only species of Northern 

 Arkansas, Kansas, and Missouri, reaching its greatest development 

 in Western Louisiana, Southern Arkansas, and Eastern Texas. 



Wood, varying greatly in quality and amount of sap, heavy, hard, 

 strong, generally coarse-grained, compact ; bands of small summer 

 cells broad, often occupying half the width of the annual growth, very 

 resinous, resin passages numerous, large ; medullary rays numerous, 

 conspicuous ; colour orange, the sap wood nearly white ; specific gravity, 

 0*6104; ash, 0'29 ; largely manufactured into lumber, especially in 

 the States west of the Mississippi Biver, and among Yellow Pines 

 only inferior in value to that of P. palustris (C. S. Sargent). 



Introduced in 1739. This is the Pine which produces the valuable 

 " yellow pine" timber of commerce. The tree does not often exceed 

 80 feet in height. Although possessing no special ornamental pro- 

 perty, it should be planted for the sake of its timber. Its habit of 

 growth very much resembles that of Pinus silvestris, and the trunk 

 is almost of uniform girth for nearly two-thirds of its length (Trans. 

 Boy. Scot. Arb. Soc. xii. pt. 2). 



P. mitis has in Denmark attained to nearly 60 feet in height, but 

 young plants of this species sometimes appear to suffer much. 



P. monophylla, Torr. and Fremont, Bep. of the Expl. Exped. 

 to the Bocky Mountains, 1842, and to Oregon and North Calif, in 

 1843-44, 312, t. 4. P. Fremontiana, Endl. Conif. 183. 



Habitat. — Near Utah Lake, Utah, to the eastern foot-hills of the 

 Californian Sierras, south along the mountain ranges of the Great 

 Basin to the San Francisco mountains of Northern Arizona. 



A small, bushy tree, 13-20 feet in height, with a trunk some- 

 times 3 feet in diameter ; dry, gravelly slopes and mesas between 

 3,000 and 6,000 feet elevation (C. S. Sargent). 



Seems to do well out of doors in Denmark.
