It is a small cactus, which does not exceed 4 cm in diameter, and maintains a globular shape, tending to cluster with growth. The spherical stem of an opaque green color, is furrowed by light ribs, from which evident white spines emerge. The spines are very short, arranged in an exactly symmetrical way. It is a rather slow-growing plant, which, due to its size, is perfect for growing in pots. When bloom, they will amaze you with its inflorescences, which are so large, that they often cover the entire stem; generally the flowers are of a nice pink color.
