I have a tree in my yard with a large vine growing up its side. The vine is about 4-5 inches in diameter. The leaves of the vine are in groups of three. Some of the leaves are very large and some are very small. The small ones resemble poison ivy, but I didn't know that PI leaves grow as big as the large leaves on my vine.

Before I remove the vines from my tree, I wanted to know what I was working with. I have attached photos.

This shows the leaf size relative to an average male hand.

This is where I cut one of the vines 4 days ago. You can see black goop where I cut.

Here are some photos of the small leaves that I think might be poison ivy

Any thought about these large leaves would be appreciated.

Thanks,
