It is a globular cactus with a solitary habit, that, over time, tends to cluster. Its stem, of an opaque light green color, has beautiful yellow spots in the points, where there is a lack of chlorophyll, which are alwyas different on each specimen and therefore make each cactus truly unique. The stem has multiple well furrowed ribs, covered with very downy areoles. The spines are very short, of a brownish cream color; often there are no spines at all. The flowering period is in spring-summer, when, on long stems, generated by the areoles, its enormous nocturnal flowers of a more or less intense pink color, bloom.
