Could be a melon sword, but the stems aren't as long as I would expect. Deffinately not an anubias, not firm enough, too many leaves, and very little stem. Whatever it is, it looks like it may not be getting enough of something.
I think it looks like a melon sword. I have had them in my planted tanks and they look really nice once they really get going. New leaves are on the reddish side and older leaves are green.
