Is this an amorphophallus?
I got this as a trade today. It was about 3 ft tall. Unfortunately the plant was banged up in shipping and separated from the bulb, but it looks like an amorpho to me, but not one I can put my finger on. The bulbs are about the size of a fist. The trunk is appropriately mottled as shown. The leaves met in the center and had 3 main branches from the crown before continuing to branch.
Any help with ID appreciated
