Purple Flower in Mahableshwar

when I saw this flower from far, my first thoughts was that it was some sort of grafting when I neared to shoot, noticed that the purple flower was the result of a creeper which grew on the white flowered plant the creeper produces the purple flower this picture is shot on 30th april 2016 (forgot to update date on camera so the exim data reads date as 1st jan 2007)
