This tree, which is well represented in the accompanying plate, closely resembles in its general 

 aspect its eastern representative, J. Virginiana, but is distinguished from it by the larger size 

 of its berries ; by its more glandular and resinous leaves, which are also less acute ; and by the 

 character of its wood, which, in all the trees examined, was white, not at all resembling the 

 dark and fragrant wood of the red cedar. 



We found it abundant on rocky and barren surfaces east of the Sierra Nevada and Cascade 

 mountains from Pit river to the Columbia. 



The largest individual of the species noticed had a diameter of three feet near the ground and 

 an altitude of about forty feet. 



The fruit forms an important part of the subsistence of several kinds of birds, especially of 

 Prince Maximilian s jay and Townsend s Ptilogonys.
