With the leaves not being round, and the faint suggestion of red edges, it looks more like a 'Jellie' that hasn't had any direct sun. I though I'd added a pic of that plant's low-light appearance to the database but I have not yet. Will work on it when I am @ home.
Red Edge Peperomia (Peperomia tricolor)
There's one in this group pot, but only 2 leaves are visible in this shot.
