Looks to me like some hybrid of E obesa and who-knows what. But it's not that uncommon a plant in cultivation. Makes great potted plant, suckering nicely. Easy to rot if overwatered in high heat times. Plants in full sun turn purply. Easy plant to snap off from main plant and just stick in potting soil and have root. No sharp spines and doesn't 'bleed' easily unless broken.
