Wildlife Spotting

This is a leaf type that I am not sure what type it is. The plant shape was an obvocate shape, which looks like the leaf above, a little round but has a dip drip. The texture of this leaf is very smooth, but you can feel the venation on the leaf. The arrangement of how the leaf grows is, sub-opposite. The margin for this leaf is the entire.Obviously, this leaf is green, so you know the color.
