Spec. Char., §c. Leaves sinuated, glabrous, acute at the base ; sinuses some- 
what acute. Cup somewhat shield-shaped. Nut roundish-ovate. (Michz.) 
A large deciduous tree. Nova Scotia to Lake Champlain. Height 40 ft. 
to 60 ft. Introduced in 1800. 
This species bears a close analogy to 
the red oak in its foliage, and to the 
scarlet oak in its fruit. It has also another 
peculiarity in blossoming every year, though 
it takes two, three, and in very cold 
climates four, years to mature its fruit. 
The leaves are large. smooth, and deeply {4 
sinuated; the indentations being sharper ‘ Sy 
and more angular than those of the leaves of * 
Q. coccinea. The acorns are of the middle 
size, rounded at the end, and contained in 
scaly top-shaped cups. The grey oak is 
found farther north than any other Ame- 
rican species, and it therefore would seem 
to be the best adapted for being cultivated in Britain as a useful tree. The wood 
is as coarse and open in its pores as that of the red oak; but it is stronger 
and more durable.
