Mystery solved.....it has been confirmed this vine is called Thladian Oliveri grown from potato like tubers with a bell shaped yellow flower with heart shaped lightgreen leaves climbing up until a heavy frost...found in Hebci China by Westner's and introduced to the New York Boldnical Gardens in 1885 -1888 ..best grown in a pot.......my friend does not wish this on anyone....
