This plant was growing at the entrance gate of a village where we live about 10 years ago. The leaf in the picture is dried, pressed between pages of a book and then forgotten. The plant is a climber, with wiry stems and very strong. Left unchecked and it could overwhelm a small tree. I don't know if the plant still grow at the site, but by the look of it, it is considered as a weed.
The pic is a scanned image, so the pic you are seeing is the actual size. Any possible of an ID or maybe a guess?
