squirrels. The shell of the nut is much harder than that of the eastern chinquapin, and the 
two species are in all respects unlike. 
It is quite common to find ripe fruit and freshly-blown flowers on the same plant at the same 
time ; indeed, I think that was the general rule when the specimen figured was collected, on 
the head-waters of the Des Chutes river, in Oregon, August 30. Hooker’s brief description 
(1. c.) is applicable to the plant wherever I saw it, except that he represents the aments as 
confined to the axils of the leaves, and to he not more than an inch in length ; whereas I often 
found the aments not only in the axils of the upper leaves of a branch, hut exclusively occupy¬ 
ing the extremity. The aments in my specimen are twice as long as in his.

This pretty oak occurred on the line of our route only on the banks of Canoe creek, in the 
western range of the Sierra Nevada, northeast from Lassen’s butte. It there formed rather a 
large shrub than a tree. It is, however, here near the northern line of its range ; and on the
