Does it have any leaves? Looks like a highly stressed pothos, which is unusual as they are one of the easiest of any houseplants to grow.

Agree, Pothos. I don't think you can kill it because it looks like it's already dead & beyond recovery. Doesn't hurt to give it a chance. If you water it and wait a couple months and nothing happens, it's dead.

We don't know the history, but it either got so dry that the roots died of shriveling, or the pot has no drain hole and at some point too much water was added and the roots rotted and died of that.

If there are any parts of it that look better than the photo with leaves, etc., you can cut those off and put them in water to root and start all over again. Pothos root very easily in water and can be kept in water for a very long time (i'm talking months even years!).

Can we please see a picture of the whole plant ?

Potting soil was being kept too wet for winter conditions.
