Christine is right, it's a terminally improperly watered Pothos
. Unfortunately it's really difficult to say under/over watered without knowing how often it has been watered and what kind of light it's in. Usually Pothos are real easy to grow and tolerant of poor care, but they can only take so much before even they give up. That being said; you could get another one, not repot it, and keep it evenly moist without being soggy and in moderately bright light and it should be okay. If you do try again and run into problems, just take some pics and let us try to help!
