A cactacea plant highly appreciated by green collectors and cactus lovers. Its stem can be both globular and cylindrical and may cluster over time. It has a slight depression at the apex and its ribs are defined by many rounded tubercles and small downy areoles, from which short and thin white spines emerge. Flowering occurs at the end of summer, when you can admire the blossoming of its beautiful bright yellow flowers.
