No rings around the pointy part of the acorn? I'd go with Quercus rubra.

No rings on the one I collected. Thanks esh =)

Doesn't look like rubra. Leaves look like shumard or scarlet. Possible hybrids make it more difficult.

Even my shumard from OIKOS looks like it has some scarlet or pin oak influence.

Looks like a pin oak to me

Looks like a shumard to me.

Acorn is not right for either pin oak or shumard oak in my opinion.

Maybe he can get a picture of the acorns once they mature.

The leaves look like my 2 pin oaks, but the trees form should tell that for you, unless the tree is heavily pruned or misshapen. My 2 pins have no mature acorns but I've seen some tiny efforts like in your pic on a couple branches. My Quercus Rubra don't match your leaves. The Shumard and Nuttalli look similar, but if had to guess Pin oak. But, I am often wrong, so it's a guess.

Well, we have a consensus, it's of the Red Oak tribe! :-D

At first, I would have guessed Q.Velutina. Don't think so now though as the subject leaves seem to have more sinuses than QV.

The acorns are throwing me off.

The leaves could be Shumard...maybe Scarlet. Not rubra. Probably not Pin.

I'm leaning toward Scarlet oak...Quercus coccinea only because the undersides of the leaves are less hairy and greener than pics I see of Shumard oaks. Shumards have browner hair. The real test is in the fall when Scarlet oaks turn a brilliant red/orangey color and Shumard won't.

Here is a link that might be useful: Scarlett

Scarlet oak acorns have {{gwi:415782}} around the pointed tip of the acorn.

Q velutina acorns have {{gwi:415783}} (for lack of a better word) on the acorn cap.

Leaves can be so variable.

It does have the very over- accentuated bristle tips of Scarlet oak. Pin or Scarlet? Isn't Scarlet thicker than Pin and Shumard? My Q. Velutina leaves are thick as my 1 Scarlet baby's leaves though. I'm sure I am not helping. Mine have no acorns yet. That may be the final bit of info for the right ID.
