Pot: 6,5 cm.
It is a small, solitary cactus that clusters over time. It has a globular shape, with a slightly flattened apex, of a bright green color. It has well-marked ribs with small white areoles, from which long and rigid light yellow spines emerge, that turn gray as the plant matures. It generates, from the areoles at the apex, large funnel-shaped flowers, ranging in color from white to light pink, with yellow-brown shades inside.
