Hi & welcome to Gardenweb! Agree with the above. If this was mine, I would scoop it out and leave the root ball sitting loosely on the surface to dry more quickly, maybe even laying it on some newspaper if it's very moist. Then snip the stem below the concentration of aerial roots and sit it atop another pot with a more chunky, porous mix that is barely moist, burying the aerial roots just enough so they don't spring back up, without packing them down at all. That looks like it will leave about 4 leaves and a couple aerial roots on the original plant. See if you can get those aerial roots to make contact with the soil and stay that way. Put both in the sunniest spot you have and let them dry out. Then go very lightly with the water for the removed top part, until the roots have a chance to go throughout the pot, just moisten the surface the first few times. If/when the original part perks back up, gently knock the old soil off of its' roots and put in the chunkier mix that dries out quickly, then finally give it more water. If the soil for these types of plants does not dry quickly, they can rot. Even just after watering, having tiny air pockets throughout the pot is good so the roots can get some air as well as moisture. So avoiding fine particles like peat and sand, and actual soil is best since these small particles fill up all of those spaces, suffocating roots and harboring too much moisture.

Looking at the leaves and the tree structure, it might be a soursop tree. The leaves have a specific smell if rubbed in between the fingers, some people make tea with the leaves.

Possibly Yucca elephantipes. If so only hardy in zones 9-11. You could get confirmation or other suggestions if you post this to Name That Plant

not without a pic ... lol ... btw.. there is a NAME THAT PLANT forum ... for future reference ... though you will probably still get an answer here ... but do note.. that though they are very good over there.. they will probably also need a pic ... lol .. ken
