I can't seem to identify this little guy.
It looks like a not terribly well Asplenium nidus, common name Birds' Nest Fern. It may be yours is suffering from insufficient light as well as a dry atmosphere, they do like a lot of humidity, so bathrooms and kitchens are often good places for these. In terms of light, bright daylight is best - a little winter sun won't do any harm.
