its leaves and general appearance in different climates. This difference is so 
extraordinary, that nearly all the botanists who have written on the American 
oaks have supposed it to be two species. In the Southern States, it forms 
a noble tree, 80 ft. high, with a trunk 4 or 5 feet in diameter ; while in New 
Jersey the tree is never above 30 ft. high, with a trunk only 4 or 5 inches 
thick. The bark is thick, black, and deeply furrowed ; and the wood is reddish 
and coarse-grained, with open pores, like that of the red oak. The leaves are 
also extremely different; on the trees in 
the south, they are falcate, like those in fig. 
1586., copied from the plate of this tree 
in the North American Sylva, i. t. 23.; in 
1586. Q. falcata. 1587. Q. falcata. 
New Jersey, the leaves are three-lobed (like those shown in fig. 1587. d, 
from the Histoire des Chénes), except a few on the summit, which are 
slightly falcated. Generally the lower branches of all trees of this species, 
growing in moist and shaded situations, have their leaves trilobed ; while 
those on the upper branches are falcated, with their lobes even more arched 
than those in jig. 1586. This remarkable difference led the elder Michaux 
to describe the specimens which he had found growing in very cold bad land 
as Q. triloba; and on the young shoots of these specimens he frequently found 
leaves deeply denticulated or lobed, like those of Q. ribra or Q. coccinea, as 
represented at @ in fig. 1587. The acorns are small, round, brown, and 
contained in slightly scaly, shallow, top-shaped cups, supported on short 
peduncles : they resemble those of Q. Banfsteri, and, like them, preserve the 
power of germination for a long time.
