Japanese, amongst which is one with leaves similar to 

 Fremont's Pine, and another with beautiful spotted foliage. 

 The wood is resinous, very tenacious, and durable. Not 

 yet tested here. 



84. P. densiflora, Siebold. Syn. P. Japonica, 

 Antoine ; P. Pinea, Gordon, in Pinetum, (1858.) Leaves, 

 from 3 to 4 inches long, from short, fringed, scale-like 

 sheaths, slender, stiff, acute, slightly serrulate on the 

 margin, convex above, concave beneath, smooth, and sub- 

 glaucous. Cones, 1 J inches long, short peduncled, conical, 

 obtuse, ligneous, somewhat pendent, terminal, and very 

 numerous ; with linear-oblong, woody scales, terminating 

 in a small, very deciduous prickle. Seeds, very small, el- 

 liptic, with a striped, dull brown, membranaceous wing. 

 Cotyledons, mostly 6. 



Although this species is found growing all over Japan, 

 it is much more plentiful at the north, and frequently 

 forms large forests with P. Massoniana. Siebold men- 

 tions isolated specimens in the environs of Nagasaki, that 

 were 40 feet high, or over. It is generally very abundant 

 on the mountain slopes, occurring at a height of from 

 1,000 to 2,000 feet. At an elevation of 3,500 feet above 

 the level of the sea, it becomes a mere bush. It is nearly 

 allied to and resembles P. Massoniana, with which 

 species it has been frequently confounded. 



Murray says of P. densiflora : tc A tree often reaching 

 the height of 40 feet, or even more, with a straight, taper- 

 ing trunk ; smooth, cinereous brown bark ; the branchlets 

 dirty cinereous brown, glabrous, roughened with the bases 

 of the persistent and falling scales." The lumber furnish- 

 ed by this species is of excellent quality, but the scarcity 

 of large trunks prevents its extensive use. The resin is 

 manufactured into salves, etc., by the Japanese, and the 

 soot is used largely for making India ink. 



In the Ternatw section of the Pine Family, there are 

 no species known positively to be natives of Japan, al-
