Senecio kleinia Instead of Tylecodon

Not knowing what a plant is should not bother me. Just because you don't know what it is doesn't mean you can't grow it. But I do have this streak in me that tends to keep me up until I figure something out. Well, that possible Tylecodon wallichii is now a most likely Senecio kleinia. I think the telltale sign is the markings on the stem.
