chinquapin oak

Chinquapin Oak Quercus muehlenbergii
Family: Fagaceae (Beech)
Branching: Alternate
Other names: Chinkapin Oak

This is not a common tree in Ontario. Its most distinctive feature are its leaves, which can often be found on the ground, or still attached to the tree through the winter. They resemble Chestnut leaves and have sharply pointed lobes (the lobes are not bristle-tipped, though, as this is a member of the White Oak group). I have not seen it very many times and only have a couple pictures here.
