So I received a new plant that was labeled as just "rubera" which looked like just a species name to me. I think rubera means red which made sense because the under side of the leaves have splashes of red. Anyways I was told the genus was Monadenium. The only name close to this is Monadenium rubellum aka Euphorbia neorubella. Sounded about right, but the only problem is that I also have that plant and that was certainly not it.

After painfully looking up every Monadenium and Euphorbia species I could find I think I've finally located the correct species, but I'm curious what everyone else thinks of if anyone recognizes it.

Here's a view of the underside of the leaf.
