This curious and interesting species of Fir was discovered by Dr. Coulter 
on the sea side of the mountain range of Santa Lucia, about 1000 feet lower 
down than Coulteri. The trunk rises to the height of 120 feet, is very slender, 
not exceeding two feet in circumference, and as straight as an arrow. The 
upper third of the tree is clothed with branches, giving it the appearance 
of an elongated pyramid. The branches are spreading, the lower ones are 
decumbent. The bractes are long and recurved, and but little changed from
