Not sure what this is, now that all the leaves are falling off they're getting harder to ID. They were kept in a vase of water, and were doing fine up until recently. I noticed the whole vase was full of roots, and I mean FULL. So I decided I'd change the water and remove any rotting roots and they all fell off. Now I have these long things and I'm not sure if I should cut them down(the longest is around 18 inches), or leave them the length they are. And, if I cut them back can I root the cuttings.
Brown nodes where leaves used to be
I need help with care as well as identification. Any help is appreciated. I've got the new vase sitting full of water until the chlorine and what not evaporate.
