It was a Dudley Watts plant, from a division.
Would you be able to trace back your plant to the original Cephalotus 'Dudley Watts' ?
I wonder if the material that was sent to you regarding what u have said on ebay in your listing can be traced back to the original plant? There are so many fake clones including 'Dudley Watts' even in Europe where I live, so if you can't trace it back to the original plant then there is absolutely no assurance that it is genuine and as I said already yours looks different...
