Pot: 6,5 cm.
This plant is the only species of the genus, it is a very small cactus, of a globular or slightly cylindrical shape, consisting of showy, very rounded tubercles, which make it extremely particular, despite its minute size. It has a beautiful olive green color, which tends to take on pleasant purple shades with the sun. The base becomes corky over time. The apex is deeply downy, and in the middle of the thick down, beautiful yellow flowers bloom in spring, that make the overall look even more spectacular!
