Pinus monticola, planted in 1876, is now 19 feet high, with a 

 girth of 1 foot. I am unable to say if taller specimens are to be found 

 in Denmark. It has produced cones. 



P. monticola esemleseens. This is a variety with a more 

 glaucous appearance than the type.

Habitat. — California, Mendocino County, south through the coast 

 ranges to San Luis, Obispo County. 



Introduced into Europe in 1840. 



Is perhaps not hardy in Denmark. 



This very distinct Pine was first discovered by Dr. Coulter at San 

 Luis, Obispo, in Upper California, to the south of Monterey, at an 

 elevation of 3,000 feet, and within ten miles of the seashore. It 

 grows straight, but rather stunted, seldom exceeding 40 feet in height. 

 Mr. Hartweg found it growing on the western declivity of the 

 mountains near Monterey, and within two miles of the seashore, 

 attaining a height of from 20 to 30 feet, and with a trunk 12 inches in 

 diameter. In this locality it was confined to a small wood half a mile 

 square, and intermixed with and surrounded by Pinus insigiiis. Mr. 

 Hartweg again met with it at a considerable distance to the south of 

 Monterey, on the ascent to the mission of La Purissima, where the 

 monotony of the bare hills was only relieved by a small forest of it ; 

 the trees, however, not attaining a larger size than those found grow- 

 ing near Monterey. Mr. Jeflrey found it a tree 40 feet high, of a 

 conical form, on the Siskiyou Mountains, at an elevation of 7,500 feet, 

 growing in moist soil, near the summit of the mountain. It was 

 named P. Murrayana by the Oregon Committee, and P. Edgariana by 

 Hartweg in the Journal of the Royal Horticultural Society. It is 

 the "Obispo," or Bishop's Pine, of the Calif ornians, and has been 

 found to be quite hardy in England (G. Gordon, "The Pinetum," 

 1875.) 



This is a very distinct Pine, the irregular appearance of its branches 

 and clustered prickly cones being difi'erent to those of anj^ other with 

 which I am acquainted. From its rather unusual appearance it is 

 worthy of a corner in the pinetum. It is perfectly hardy, not at all 

 fastidious as to soil or situation, of the easiest culture, and valuable for 

 planting as game shelter, or for the ornamentation of high-lying and 

 breezy situations (Trans. Roy, Scot. Arb. Soc. xii. pt. 2).
