Need help identifying plant
I had a plant pop up in my garden that I'm curious about. It looks like a minature version of a sweet potato vine but the leaves are very tiny. Now it has grown what looks like miniature Idaho potatoes that are very hard and I suppose some type of seed pod. They are dropping off all over my garden and I'm not sure if they are harmful or not. I'm removing all that I find. Can anyone help identify or should I include a picture?
