I have this unknown vine growing on my fence and I have no idea what it is. The berry is almost melon-like and very dark green but about the size of a grape. Can anyone help?
A picture is worth a thousand words. Any chance you can upload an image? Only these two come to mind. Ibervillea lindheimerii http://davesgarden.com/guides/pf/showimage/87193/ Melothria scabra http://davesgarden.com/guides/pf/showimage/161410/
There are tiny yellow blossoms on it and it does look like the Texas Globeberry. The leaves are light green and rough on both sides
