new species of Pinus; and I have to regret that the specimens of three of 
them are without leaves, Dr. Coulter not having been able to find them, from 
the want of a convenient opportunity to arrange his vast collections. The 
cones of these, however, are so marked as to leave no doubt of their con- 
stituting three very distinct species. 
l. Pinus CourrERi. 
P. foliis ternis prælongis compressis: vaginis filamentoso-laceris, strobilis ob- 
longis solitariis maximis: squamis cuneatis: apicibus elongatis incras- 
satis lanceolatis mucronatis ancipiti-compressis aduncis.

Discovered by Dr. Coulter on the mountains of Santa Lucia, near the Mis- 
sion of San Antonio, in latitude 36°, within sight of the sea and at an elevation 
of from 3000 to 4000 feet above its level. It was growing intermingled with 
Pinus Lambertiana. The tree rises to the height of 80 or 100 feet, with large 
permanent spreading branches, and the trunk is 3 or 4 feet in diameter. "The 
leaves are longer and broader than those of any other Pine, and the cones
