wide and tall. The colour of the epidermis is dark grey-green or
olive-green, with violet tints.
Spines: Short glass-white with darker tips, bristly, awl-shaped
to needle-like, radials all straight (or sometimes with one central

Cultivation: It is easy to
grow, and recommended for beginners.
It prefers a gritty, porous mix, with a pH
slightly on the acidic side. Full sun to light shade.
Water regularly in
summer, but do not over-water (the root system is rot prone), and allow the
pot to dry out between waterings. Keep dry in winter.
Hardy to -4°C, it
will take low temperatures when dry, and requires a winter rest period.
This species will occupy a small flower pot comfortably and
remain a manageable sized house plant.
Pest and disease: This
plants are subject to mealy-bug attack and to fungus and rot problems,
brought about by overwatering and high humidity.
Note: It would appear that
in cultivation they grow larger and cluster more vigorously than in
habitat.
Propagation: By seed or offsets.
