It is a small cactacea with a generally solitary habit that can cluster over time. Its green stem, embellished with wonderful yellow variegations, is completely enveloped by its small white spines. From the numerous white areoles, stiff and straight red-black spines emerge, which converge upwards. It blooms from February to April, producing small funnel-shaped flowers in pink and magenta colors.
