BLACK JACK OAK
Twig, two-thirds natural size. Leaf, one-third natural size.
The leaves are of a leathery texture, dark green on the upper surface, lighter, hairy, and brown-scurfy below. The leaves are wedge-shaped, 4 to 10 inches long and about the same in width. There is a considerable difference in the leaves of this oak both in size and shape.
The fruit is an acorn about three-quarters of an inch long, yellow-brown and often striped, enclosed for half its length or more in a thick light brown cup.
The wood is heavy, hard and strong; when used at all, it is used mostly for firewood and mine props. It is also used for the manufacture of charcoal.
SHINGLE OAK Quercus imbricaria Michx.
THIS oak is found throughout the State with the exception of the extreme north portion. When growing alone, the tree develops a symmetrical rounded top, conspicuous on account of the good-sized, regular-shaped, oblong leaves which differ in shape from most other native oaks. It forms a handsome tree. It is sometimes incorrectly called “laurel” oak.
