Description: It is a small cactus that usually grows solitary or in groups.
Stem: Soft, about 5 to 7 cm across, gray-green to dark green, at first spherical, egg-shaped, then elongate as they ages. The crown is slightly depressed and covered with whitish wool
Ribs: 10-14, compressed, running downward and divided into slanting tubercles whose arrangement creates the impression of a wavy line.
Areoles: 3 mm across, with grey-white felt.
Spines: Of different length, usually straight or slightly bent, directed upward, dark brown to blackish in youth, later grey.
Radial spines: Approximately 10 or less, about 1 cm long.
Central spines: 1 to 3, strong, dark, frequently red; the upper spine usually attains a length of 3 cm and is often hooked and thickened basally (but sometime the longest of them may reach the length of 4-6 cm).
Root: Thick taproot.
Flowers: Arising from the basal tubercles on the side of the plant, up to 7 cm wide, their colors is very variable, going from yellow to orange, tomato-red, vine-red and also happening through all the imaginable tones of violet. All of them have in common that the hymen (or throat ring of the flower) is always of a very dark purple-violet to black, thickened at the edge and glossy. The stamens are purple, the anthers yellow.
More...Cultivation and Propagation: It is a summer-growing species that offers no cultivation difficulties. Water regularly in summer (but do not over-water). The fluctuations of temperature between the day and the night (especially the temperature reduction at night) and fresh soil, greatly contribute to the health of plants. They require as much sun and light as possible, and pure air availability. They cannot tolerate stagnant heat. The substratum must be very porous, slightly acidic, with good drainage. They require a deep pot to accommodate a large root system. It is quite frost resistant if kept dry (hardy to -5° C).
Propagation: Propagate by seed or shoots.
