Syngonium Showing Three Leaf Types

This very old potted syngonium on the back sun porch is showing its interesting leaf types. Some leaves have marbled variegated leaves of green and white, some leaves are solid white, and others are solid green. Some leaves are split evenly with a white half and a green half. People have asked me if there are 3 or 4 different vines in the pot, but I explain there is only 1 original vine and I never know what type of leaves will emerge.
