Compare the leaves of two plants from similar species. The left leaf is from Epipremnum pinnatum (which was previously called Scindapsus aureus); it has a shiny surface and yellow spots. The right one is from Scindapsus pictus, it's surface is more smooth and there are silver spots.
The shape of the leaves is almost identical, and so is the growth form of the plants; they both make long runners. The Scindapsus pictus was generously donated by my colleague Matthias Thorn, who let me cut off a leaf from his plant.
