PINUS PORPHYROCARPA 
VA 
Description. —The trees are said to be readily distinguishable from P. monticola by their darker and 
more glaucous foliage; and the crowded rows of stomata in the leaf enable any one to distinguish the 
young plant without difficulty. 
Geographical Distribution .— We know nothing of this further than that the plant has come from the 
same districts as the true P. monticola. 
History. —Our attention was first directed to this species by Mr. Thomas Patton of Glenalmond, 
who informed us that he had two kinds of P. monticola , one producing white cones, and the other purple 
cones. We then remembered that Loudon said something about red cones; and on referring to his work, 
we found that in describing P. monticola he mentioned that “ among Douglas’ specimens there, is a variety 
with red cones from which no plants have yet been raised.” This is doubtless the purple-coned species 
which we now describe. Mr. Patton has been kind enough to send us specimens of the different parts of 
the tree, from which the foregoing figures have been taken. 
Properties and Uses. —Yet to be discovered. No doubt the same as those of the true P. monticola. 
Culture. —Not different from that of P. monticola. 
Commercial Statistics. —Not yet in the trade ; but as—if our view is correct—the species can be easily 
recognised, even in the young state, by subjecting the leaves to examination with a lens, the reader has it 
in his power to supply himself by visiting the nursery grounds and scrutinising the plants for himself. If 
we are right, he can supply himself with plants at the price of P. monticola. If we are wrong, he is no 
loser, for he then only gets what he pays for.
