The leaf in my 'thumbs' is a,Q nigra. I know fairly certain I have post oak or sand post oak. So is that what the others are?












Pic 2&3 are a sapling 5' hi and as big around as my little pinkie, both size leaves on that one sapling.

Hey kitt! Confused VV here.

Can you either 1) label each of those pictures with what you know and don't know; or 2) list out (1, 2, 3, 4) in a subsequent post as to what is what in each of your images.

#4 sure looks like White Oak young growth close, with Post Oak canopy outlined against sky - but I suppose it could all belong to a Post Oak.

Showing the leaves of the unknown alone is helpful, especially if you can show the leaf margins clearly. If there are ANY bristle tips on the lobes, then it cannot be a member of the White Oak group (which all the oaks you mention belong to).

If I understand the question, 2 and 3 resemble Water Oak.

Bad or great area depending on perspective, post oaks leaves resemble a cross, but we have variations. The water oak, Q nigra is the only one I am sure of. All native sandy loamed dry creek area.
Porkpal, the tips of those leaves in 2& 3 shouldnt have tips. However, sometimes here smaller leaves near the ground camo themselves to protect from predation. I will have to go look at the trees in question again. My thumbnails weren't good shots. The one in the air is 20' above ground, cant get closer. White oak group, okay.
