want of it we know nothing, and have not heard of it in planted 
grounds. 
Coulter’s or Sabine’s Pine. P. Coulterii (P. Sabiana, P. 
viacrocarpa). —This species is usually found associated with the P. 
Benthamiana, but on lower elevations. It is a lofty tree, with 
slender branches and very long foliage borne near the extremities 
of the limbs. Not a pleasing tree. 
California Mountain Pine. P. monticola. —A species closely 
resembling the white pine of the eastern States, and therefore of 
little value in a collection where the latter is growing. 
American Cembran, or Contorted-branched Pine. P. 
flexilis. —A tree of very slow growth, indigenous on the mountains 
of northern Mexico' and California, at elevations of from seven 
to fourteen thousand feet above the sea. It varies in size 
from a tree from sixty to eighty feet high near Sante Fe, to a low 
flat-top shrub, only a few feet in height, and “ so compact that a 
man may walk upon it,” where found at its greatest altitude above 
the sea. It forms a tree of oval outline like the European cembran 
pine, the lower branches horizontal, the upper ones ascending, and 
both large and somewhat tortuous, but very flexible; whence its 
name. The foliage is said to resemble most that of our white pine, 
but the leaves are shorter and stouter, and the branching more irreg¬ 
ular. Supposed to be quite hardy. Desirable for great collections. 
Fremont’s Pine. P. Fremontiana. —A small, nut-bearing tree, 
found in the upper elevations of the Sierra Nevada range, from 
five to seven thousand feet above the level of the sea. It has 
many and slender, spreading branches, which are fragrant when 
bruised. It is a very slow grower. Whether hardy and of beauty 
enough to give it value east of the Rocky Mountains is yet a matter 
of experiment. Height twenty feet. 
Hartweg’s Pine. P. Hartwegii. —“ A handsome tree growing 
from forty to fifty feet high, with a dense compact head of a fine
