Ix the autumn of 1826, in the country southward of the river 
Columbia, in northern California, I had the good fortune to 
make some valuable additions to the highly ornamental and 
useful genus Pinus. The object of this paper is to put on 
record one of the most curious and interesting species of that 
genus, the specimens of which, together with the description 
made on the spot, I had the misfortune to lose in the course of 
my travels four years ago. I cannot recall to my recollection, 
without feelings of deep regret, the loss I then sustained of the . 
greatest and most important part of my collections. So remark- 
able a tree I could then, perhaps, have described from recollec- 
tion accurately, but I was fearful lest errors might unavoidably 
have crept into it; and having found it a second time in the 
greatest perfection, I now venture to send the present short 
notice of it for the purpose of insertion in the Transactions of 
the Linnean Society, should it be considered as deserving a 
place in their valuable records. 
This tree, so far as I have yet observed, attains to but a small 
size as compared with those species of the genus which inhabit 
the northern and western parts of this continent. The trees are 
of a tapering form, straight, and of regular growth, 40 to 120 
feet in height, 2 to 12 feet in circumference, clothed with 
branches
