Could it have been the Portulacaria afra?
Sometimes called "elephant jade" and "small leaf jade."
These have small, dense leaves, but a wrinkled trunk.

Could it have been the Crassula variety called "Crosby compact"? I think this is a miniature jade.

Here is a link that might be useful: jade

Thank you both. I should have paid more attention to the plants while there. Have to go back to that area next week, and will either get the name from the owner, or will try to get a good picture.
I suspect that it is Portulacaria Afra, but the "bonsai" treatment is confusing me.

Thank you,
John

Portulacaria afra is favored for bonsai treatment.
It has a more gnarly and textured drooping form.
You can pinch the stems to encourage even smaller
growth. I've not done this, mind you, I'm only
re-iterating what I've read around the Web.

Picture would be great!
