Not sure about 1 and 2, but 3 is quercus phellos.

See, that's what I thought too at first, but all three pics are from the same tree.

Someone was complaining about young oak leaves being confusing. I swear there should only be like 10 species of oak lol.

I like the color!

Looks like Water oak to me, although they don't typically grow on dry sites.

Wow, water oak hadn't even occurred to me. From everything I've read, you guys are exactly right. Thanks very much. Also, I did a poor job describing the site it's on. It's definitely more of a moist upland site, which apparently water oaks are found on sometimes. A few of the range maps I saw had them about 2 hours south of me, but then some had them coming all the way from east to west across NC, barely reaching into east TN, which is exactly where I am, so that verifies.

Also, Embothrium, i just realized that key was made by one of my professors. Pretty neat.

Another vote for water oak. That is very typical for their foliage when they are young.

I've been acquainted with oaks all my life, and one thing I've learned over the decades is that they can't read range maps, in fact, they can't read PERIOD! LOL.

Agree, you've got a water oak there. Interestingly, late season vigorous growth on my water oaks is juvenile, as opposed to the mature expression of the foliage produced at first flush.

I first suggested Quercus nigra then saw that made-to-order web page, replaced my previous post with what is there now.

Down here Q.nigra usually occurs in the same areas as Q.laurifolia, and it can sometimes be almost impossible to ID the younger saplings.

I thought of that one also. I used to volunteer at a now-closed nursery run by an enthusiast who grew a varying and wide range of oak species from seed.

The "Water oak" leaves that I've seen don't look like the pics above, but, if you guys have seen leaves like that on "Water oaks" who am I to disagree? I don't know what other oaks to say those leaves are from, but, they are certainly in the "red oak" group, most "Water oak" leaves are more "Diamond shaped" than those on the pics. If I HAD to guess I'd say "Cherrybark oak" or another southern RED oak.

The diamond shaped leaves are the adult leaves. Seedlings and strong/epicormic growth on mature and near mature trees can have foliage as in the OP. Then there is the subject of hybrids. All the species being discussed are red oaks, and will hybridize. I have a volunteer I've been watching that looks like a cross of water and southern red, time will tell, or not lol.

Young water oaks that are shaded can have almost any leaf shape. Leaves that get full sun are usually the typical rounded spatulate shape.

Okay, good to know, you guys are in the south where those trees grow, I'm not. My example for "Water .Oak or Q. Nigra was on the website for Mossy oak natives nursery, and it was surely a mature one. I did see 1 in Williamsburg, Va also, very nice formed tree BUT I know they are short lived or I would plant 1 .
