Habitat. — Japan. Common in the islands of Nij)pon and Kiusiu, 

 on the mountains. It grows as far as to South-western Eso and Sikok. 



Introduced into Europe by Siebold & Co., of Leyden, in 1854. 



As far as I know we have only small plants in Denmark, I 

 have seen a plant that had commenced to bear cones in South Sweden, 

 but it was killed by the frost. Our young plants look well.

In Poezl's Catalogue, 1857-58, it is called Pinus hkmco, P. 

 magnifica, P. Ocampi, P. Ocampi Devoniaiui, P. Thibaudiana, and 

 P. Zitacuaria. 



Habitat. — Mexico. Hartweg found this at Ocotillo, between Real 

 del Monte and Regia, on the most elevated points of the mountains. 



It has been tried out of doors, but is not hardy in Denmark. I 

 possess cones of it in my collection.

Habitat. — New Mexico, between Cimaron and Santa Fe, in great 

 numbers ; also in Arizona. Dr. Mayr says its habitat is as far south 

 as Pike's Peak, in Colorado, on dry, stony soil. In Colorado it will 

 ascend as high as 8,400 feet. He calls it "an upright dwarf Pine." 



Introduced into Europe in 1848. 



A small tree, 20-30 feet in height, with a trunk 1-3 feet in 

 diameter ; dry mesas and slopes, generally on lime or sandstone, 

 reaching in Colorado an elevation of 9,000 feet (C. S. Sargent). 



Very likely not hardy. 



P. Elliotti, Engelmann. Does not seem to be hardy.
