Trying to find out what kind of tree this is. Don't know if this is poisen sumac or not. I live in south Texas.

We have a lot of that in our forests , too. Always thought they were young Hickory Nut trees. In the bottom photo are Muscatine Vine.

The first pic is of Berries attached to larger trees with the same leaves

So can you be 100% sure it's not poisen sumac

This is the database for poison sumac... Poison Sumac (Toxicodendron vernix)
Compare to yours.

Doesn't look the same to me.
Though I'm not sure what yours is, I think it may more resemble Walnut.

Just saw this same post in Ask a Question... The thread "Please help ID" in Plant ID forum
You received some answers there too.

Is it growing in a wet or swampy area? What I read was that poison sumac grows almost exclusively in those conditions.

Compare to Black Walnut (Juglans nigra)
https://www.google.com/search?...

The leaves look like Soapberry, but the fruit and trees look too large.

Not sure what it is, but it's not hickory or black walnut because the leaflets are not toothed, or at least they don't look toothed to me in the pictures. I can't really see the berries clearly in the tree pictures to get an idea of their size in relation to the leaves. In the top picture the perspective may be making them look bigger than they are. Is it possible to get a picture that more clearly shows their relative size?

Edited to add, it does rather look like soapberry as Porkpal suggested. Apparently western soapberry grows to 35 feet.

the tree looks like a Juglans of some type maybe butternut or heartnut

It has to be something with leaflets that are not toothed, which rules out both butternut and heartnut unless there are teeth that I can't see in the pictures.

The bark seems to match Porkpal's suggestion of soapberry too. We only seem to have pics of ripe berries in the NGA database, here's a picture of the trunk from Google:

Leaves and berries from Texas A&M:

They give the tree height higher at 50ft.

wow after seeing the pics in the link I think porkpal is right also. I never knew soapberry grew to be 30 something ft tall, you learn something new everyday.

Me neither, actually. None of the trees around here are more than about 20' tall.

Going back out to the property this weekend and try and take better pics. I would say the berries are marble size. The trees are not in water but about 50 from a creek and the whole property is mostly sand.

Still sounds like Soapberry to me.

I think @porkpal got the ID right on this one ... it certainly looks like Western Soapberry which is found in Southern Texas. The fruit is toxic.
