I looked up and saw the 'fruit' on this vine, which was winding it's way up a palm tree. I've grown the plant myself and had never seen it fruit before. Thought I'd be able to find the name of it without any trouble but have searched without luck. Hopefully someone out there knows. I think of it as an old fashioned vine and thought it would be a philodendron of some sort but none of the photos I've found so far look like this.
