and in the Isle of Man. The late Mr. Farrant, 

 from the latter place, furnished me with much 

 useful information regarding such rare species as 

 Pinus patula, Picea religiosa, and others that 

 succeed well in that favoured spot. 



The so-called species, P. macrophylla, with 

 longer leaves and spiny cones ; P. Lindleyana, 

 with shorter leaves and smaller cones ; P. Win- 

 cesteriana, P. Gordoniana, and P. Grenvillece, can 

 only be recognised as forms of this very variable 

 species. 



P. MONTicoLA, Don. Vaucouvcr Island, British 

 Columbia, Oregon to California. 1831. — A distinct 

 and beautiful hardy pine, that is well distinguished 

 by its narrow branch-spread and silvery green 

 foliage. In a specimen of 80 feet in height the 

 branch-spread is only 18 feet, though ample space 

 has been allowed for development. The leaves 

 are about 3 inches long, arranged in fives, rather 

 rigid and rough on the margin. Cones are pro- 

 duced plentifully all over the tree, and resemble 

 greatly those of P. Strobus, but they are smaller 

 generally, being 5 inches long, nearly 2 inches in 

 diameter, and cylindrical. They are usually bent 

 or curved. A peculiarity of the bark is that it 

 splits into square plates, but is never ragged or 

 untidy, and is of a pleasing ash grey colour on 

 the younger, and darker on the older portions. It 

 produces timber rapidly, a specimen at Esher in 

 Surrey having attained to fully 70 feet in height 

 in forty years, with a clean and well-rounded bole 

 that girths 7 feet at a yard from the ground. In 

 dampish, loamy, or sandy soil it grows well. 



As a timber-producing tree P. monticola is likely
