It is a globular cactus with a solitary habit, which can occasionally be clustered at the base. Its bright green stem, slightly concave at the apex, has multiple slender, well furrowed and wavy ribs, equipped with small white areoles. The radial spines are thin, short, straight, of a white color, while the central ones are larger, long and flat, of a yellowish color with darker tips. Flowering occurs in late autumn at the apex of the plant, generating small, funnel-shaped flowers of a pale pink color with purple and red central streaks.
