I found a variegated Dwarf Brazilian in one of the tissue culture vessels where I work, so I took it out and grew it for a little bit to see if it would keep its variegation but after a few leaves it turned all green. I gave it away to a friend and he just sent me this photo, the first pup it produced is now producing variegated leaves. I have another one which appears to be stable as well, these are 2 variegated plants of the 4 or so I have seen produced from the tens of thousands of plants I have seen in the lab.
Here is the other one I found that is not too strongly variegated but appears stable.
