This is from my pot plant you see on the left. If you identify it, please let me know!! it sort of looks like a fig leave but it is not. ..

Update (after the third comment and exhaustive investigation!!) thanks to my clever book on plants: it's an aralia. More precisely, it's a fatsia or Japanese Aralia. See a fantastic shot here. I also learned it only grows flowers when the plant is growing outdoors. Like mine!
