those on the trees. This is apt to be the case in the young 
growth of all the oaks. The lobes are acute, or blunt, most 
of them tipped witha bristle. Some leaves are pointed as on 
the trees, and others are broader at the apex, ending in three 
lobes, resembling those figured by Dr. Brendel from a hybrid 
oak, Q. Leana, near Peoria, Ill.4¢ The leaves on the upper 
part of the trees showed a tendency to a deeper lobation than 
those on the lower limbs, especially than those on adventitious 
shoots of the trunk. The leaf surface is glossy, having about 
the same luster and color as that of the black and the scarlet 
oaks, but paler than in the shingle oak. In the mature leaves 
shoots, are more or less rusty-pub t, especially on the 
lower surface, about as much so as in Q. imbricaria. The 
margin of the leaves, particularly when young, is a little rev- 
to five-angled, larger than those of Q. imbricaria, but not so 
rv or rusty-downy as those of Q. tinctoria. The hairs on
