Areoles: Up to 10 mm large woolly.
Spines: Absent.

Notes: You might get some other names which are effectively the same plant.
This cultivar has been named "KIKKO" for its close resemblance to the famous Japanese Astrophytum myriostigmaSN|1845]]SN|1845]] cv. KIKKO.

Cultivation and Propagation: This plant is usually found grafted but it proved to groove well and pretty easy on its own roots too. Water regularly in summer, keep rather dry in winter, but can handle excessive water to few water, best for half-shade but grow well in full sun and full shade too (but in full sun turns an uneven brownish red colour).
Propagation: Grafting, cutting or seed (seldom available).
