Origin of Name
Astrophytum myriostigma nudum cv 'Kikko' is a cultivated variety of Astrophytum myriostigma. The name 'Astrophytum' is derived from Greek, meaning 'star plant', a reference to the star-like shape of the cactus. 'Myriostigma' means 'many spotted', referring to the white flecks typical of the species. The term 'nudum' indicates a lack of these white flecks, giving the plant a more uniform green color. 'Kikko' is a Japanese term used in cactus cultivation to describe a pattern resembling a tortoise shell, alluding to the angular, geometric appearance of this variety.

Technical Description of Plant
Astrophytum myriostigma nudum cv 'Kikko' is characterized by its unique, ribbed body with distinct, raised tubercles that create a geometric, almost art-like pattern. This variety lacks the white flecks common in standard Astrophytum myriostigma, resulting in a smooth, green surface. It typically forms a solitary, columnar stem that can grow several inches tall. This cultivar blooms with large, yellow flowers from the apex, contrasting beautifully against the green body.

Origin of Plant
The species Astrophytum myriostigma is native to the desert regions of Northeastern and Central Mexico. However, the 'Kikko' cultivar, like other cultivated varieties, is a product of selective breeding and does not occur naturally in the wild.

Conservation Status
As a cultivated variety, Astrophytum myriostigma nudum cv 'Kikko' does not have a conservation status. However, the species Astrophytum myriostigma is not currently listed as endangered.

Care instructions
Astrophytum myriostigma nudum cv 'Kikko' should be planted in well-draining soil, ideally a cactus mix. It prefers bright, indirect light but can tolerate some direct sunlight. Water moderately, allowing the soil to dry completely between waterings. Reduce watering in winter to prevent root rot. This cactus is not frost-tolerant and should be protected from freezing temperatures. Minimal fertilization is required. Regular inspection for pests and diseases will help maintain the plant's health and distinctive appearance.
