400 Select Plants for Industrial Culture and 



Pinus reflexa, Engelmann. 



California. Allied to P. flexilis, belonging to the Strobus section, 

 but wkh comparatively large inappendiculated nuts. 



Pinus religiosa, Humboldt. (Abies religiosa, Lindley.) 



Oyamel-Fir. Mexico, from 4,000 to 11,500 feet above the sea- 

 level, thus reaching the limits of arboreous vegetation. A magnificent 

 tree with somewhat silvery leaves, growing to a height of 150 feet, 

 stem reaching 6 feet in diameter. The wood is particularly well 

 fitted for shingles and laths. This species endures the winters of 

 Middle Europe. 



Pinus resinosa, Solander. 



Red Pine. North- America, principally Canada and Nova Scotia, 

 but extending to Pennsylvania. It attains a height of 150 feet, the 

 stem a diameter of 3 feet. It is of rapid growth, and on account of 

 the reddish-barked stem ornamental [Sargent] ; delights in sandy soil, 

 naturally drained, and on such produces the best quality of timber 

 [Fernow] ; the wood is hard, fine-grained, strong, elastic, heavy and 

 durable, to various extent resinous, and useful for ship-building and 

 structures of various kinds. A search should be instituted after 

 least odorous essential oils, some of which perhaps yielded by parti- 

 cular pines, to effect the fixing of delicate scents, which could not'be 

 isolated by distillation or other methods. 



Pinus rigida. Miller.* 



American Pitch-Pine. From New England to Virginia. It grows 

 to a height of 80 feet. Timber from gravelly or rocky soil heavy 

 and resinous, from damp alluvial soil light and soft ; used for build- 

 ing. But the tree is principally important for its yield of turpentine, 

 resin, pitch and tar. It is suitable for sea-shores; it will also grow 

 in the driest localities, as well as in swamps. Prof. Meehan mentions 

 this as the most rapid grower among North-East American pines. 

 Dr. M. T. Masters remarks that this species is particularly apt to form 

 adventitious shoots from the trunk, so that by cutting away the top 

 a bushy ramification will be produced. With P. Tseda among the 

 most oleous and resinous pines, to be disseminated million-fold in such 

 extensive malarial regions, as cannot be readily or profitably drained, 

 to subdue miasmata by the copious evolution of the double oxyde of 

 hydrogen and ozone. The first trees in Australia were reared by the 

 writer of this work. 



Pinus Sabineana, Douglas.* 



Californian Nut-Pine or White Pine. From California to the 

 Rocky Mountains. Height to 150 feet; stem frequently 5 feet in 

 diameter. Leaves unusually long. The wood is pale and soft ; 

 according to Dr. Gibbons it is hard and durable when seasoned,
