Here's a few pictures, although I'm disappointed in how blurry they turned out. Sorry. If you cannot use these, let me know and I'll try again.
I ran across a pretty good site that looks helpful. It looks to lean towards Q. texana for this one, I think.

I can see some slight tufting at the leaf veins... but not significant.
I also noticed that many of the leaves had an uneven margin at the stem.
