I don't know for sure what this plant is cuz it is so old, but I think it's a philodendron. It was in wet dirt (overwatering, bad drainage) for a long time and I am trying to save it. I took it out of the wet dirt and cleaned it off and put it in clean dirt for probably 2 months. It has not seemed to do anything. It hasn't died and it hasn't grown any new sprouts. So now I have taken it out of the dirt and put it in water for maybe 3 weeks. Again it isn't doing anything, no new roots, nothing growing on the old root -- except this strange transparent sac forming around the main root. Any idea what it is?
