in Extra-Tropical Countries. 275 



to 5 feet in diameter. The timber of young trees is pale, of older 

 trees dark-colored; it is principally esteemed for ship-building, but 

 also used for furniture. The tree yields a peculiar kind of turpentine, 

 as well as a valuable tar. Although ascending mountains in South- 

 Europe to the height of 4,000 feet, it thrives best in sandy coast-lands, 

 where in ten years it will measure 25 feet, and finally will become a 

 larger tree than on firmer lands. M. Boitel has published a special 

 work on the importance of this pine for converting poor santl-land 

 into productive areas, referring also to P. silvestris and P. Laricio for 

 the same purpose. According to Mr. W. Irvine Winter it will resist 

 an occasional heat of 118 F. in the shade. We find the Aleppo-Fir 

 one of the best of evergeen avenue-trees in Victoria, as first proved 

 by the writer. It is content with the poorest and driest localities, 

 and also here comparatively rapid in growth. 



Firms Hartwegii, Lindley. 



Mexico, 9,000 to 14,000 feet above sea-level. A pine, reaching 

 150 feet in height, with a very durable wood of a reddish color; it 

 yields a large quantity of resin. 



Pinus Hookeriana, McNab. (Abies Hookeriana, Murray.) 



California, at 5,000 to 6,000 feet elevation. A fir, allied to P. 

 Pattoniana, but distinct (Dr. McNab). Height of tree to about 300 

 feet, stem perfectly straight. Wood hard, of a reddish color, with 

 handsome veins. Not a resinous tree. Hardy in Middle Europe. 



Pinus Hudsonica, Poiret. (P. Banksiana, Lambert.) 



Grey Pine. Colder parts of North-America, both eastern and 

 western up to 64 north latitude. Height of tree as much as 40 feet;, 

 in the cold north only a shrub. The wood is light, tough, resinous 

 and easily worked. 



Pinus inops, Solander. 



Eastern North- America. The Jersey-Pine. A tree content with 

 barren soil, attaining a height of 40 feet, available for fixing drift- 

 sand on coasts. Easily disseminated. Remarkably rich in resin, 

 hence to be classed with pines most desirable for sanitary plantations. 

 Wood reddish-yellow. P. Virginiana (Miller) is by far the eldest name. 



Pinus Jeffrey!, Murray. 



California. A pine, to 150 feet in height. Hardy at Christiania, 

 Norway. The glaucous branchlets of aromatic fragrance with thinner 

 and greyish leaves, the greater size of the fruit-cones with thin and 

 recurved spines to the scales, the larger nutlets and more numerous 

 cotyledons separate this pine from P. ponderosa (Eugelmann, Sargent, 

 Perry). 



Pinus Jezcensis, Antoine. 



Amur and Japan. This spruce is closely allied to the N. W. 

 American P. Sitchensis. Picea Ajanensis (Fischer) is identical. For 

 synonyms see Dr. Masters' essay in the Journal of the Linnean 

 Society 1881.
