Okay so I'm out at the back of the property when I see something green growing in a tree!! Wow I think what could that be, (except a couple of cypress) all the trees are deciduous. It is this huge thorny vine.

Is this one of those other 11 species of smilax? These leaves appear less lobed but sure does look like smilax? And with this one, the branches spread out like a fan. This is one of the many branches coming off the main vine.
