Quercus marilandica (blackjack oak) 

Such an informative video, thank you so much. We have one of these oak trees in our backyard and have wondered what type it was and curious about the peculiar shaped leaves. (Chattanooga)

Thank you so much! I was looking for the bristles too! You really helped me to identify this tree. The leaves are most unique!

Outstanding video! I wish many of my college professors were as interesting as you. Geez, that was a long time ago...lol

I have several of these which appeared in my backyard this Spring. Do they produce colorful Fall display do you know? If so I will leave them where they are. If not I'll remove them for more colorful Maples and Dogwoods.
