Defcription. —A tree reaching a height of 150 feet, and 4 feet in diameter. So far as we may judge 
from report, and the figure of the tree given in the “ Edinburgh Philofophical Journal,” loc. cit., it cannot be 
faid to be a handfome tree, but may be defcribed as looking naked and tufty. The beautiful cone, however, 
is in itfelf an object of attraction. 
Geographical Dfiribution. —Found by Jeffrey, in Shafta Valley, in North California. Alfo by Pee¬ 
bles, on the top of Scot’s Mountain, one of the Shafta range, a locality where fnow falls early and lies late. 
Hiftory. —We owe the difcovery and introduction of this tree to the Edinburgh Oregon Botanical 
Affociation. That Affociation was eftabliflied in 1850, by a number of Scottifh arboriculturifts, with the
