Can anyone please tell me what it is? Best guesses are some kind of chinese taro or philodendren congo green. This plant was much larger but seems to be shrinking. It's 15 years old and from my grandfathers funeral, so I would like to get it back to thriving. Thanks!

Its a Thaumatophyllum, most likely Xanadu judging from the size of the trunks that have partially died off. Looks like it died back for some reason (did it freeze?) and the growing tips on the old trunks were killed back, then it resprouted new leaves from the viable point on the trunk.

I agree, it looks like Thaumatophyllum xanadu formerly classified as Philodendron xanadu.

Thank you guys! I was confused because of the leaf shape and what not, but perfect timing, a very old picture of my plant popped up in facebook memories and it use to have different shaped leaves! It does very much look like Thaumatophyllum xanadu.

It did not freeze or anything. I recently had to move the plant after repotting it. I had it near the front door and realized my dog was knocking leaves off with his wagging tail! I am hoping the two empty pieces will regrow leaves, but if not do you suggest removing them? I would like propagate this plant but was too afraid to cut anything off till I knew what it was and how to correctly go about it.

I'd suggest trimming off any roots that are no longer viable (any that are rotten or dead) and pot the plant into a small container with drainage holes, using a light, airy potting soil. The tips of those bare stems can also be pruned back and I'd sprinkle a little cinnamon onto the cut tips afterward to help prevent any possible fungal issues. Eventually, new growth will emerge just below the cut.

Yes, juvenile leaves will look very different from more mature leaves. This is my mature T. xanadu:
