Paper Mulberry - is common name, but this common name can belong to more species.

they say it is invasive and in Texas.
I still have not seen this plant. But I'll be more careful in what appears to be like mulberry.
Maybe somebody know the plant and can tell you more or if I am wrong ID of plants from pictures above.
