Can anyone help me with these?

Here's 2 pics of a plant that grows horridly in my trees as well as everyone else's trees it seems in the local area! The 3rd pic is of the "potatos" they seem to leave on the ground & grow from! Does anyone here know what these are & how to irradicate them?

Could they be climbing yams?

I've never seen those before. After checking out your link, Dandave, I think you got it right.
