If it had some tuber, I'd say maybe a chance. But I am not sure it will do for you.

These guys clone xanthasoma from cuttings. Maybe if you contact them they can give you some info?

"Our lab technicians use scalpels, microscopes and petri dishes, to produce thousands of little plants from a single, tiny growing tip cut from a superior "mother" plant. Our plants are grown on a gelled nutrient rich medium with growth regulators. "

These do not have large tubers as small plants .
I would put it into a small pot with pure sphagnum moss , you should get roots in no time .
Just plant out or repot when rooted well.

Thanks everyone for all your help. Aroideana I have followed your advice and am keeping my fingers crossed!!
I will call Agristarts on Monday just to see if they have any further advice.
