Mammillaria carmenae

Ah, a few forms of carmenae. As well as for bocasana this specie must be the sweethart of nurseries. They could make as much different forms as they want. Money, money, money....

You are right Hugo, but M. carmenae is very lovely plant. I still have got one form of this plant with pale pink flowers but I didn't take a picture this year (I forgot it).
