First description: Neomammillaria albicans by Briton & Rose 1923
 
Origin:  Mexico (Baja California Peninsula and various islands, Mexico.

Habitat:  Grows on limestone-rich substrata, altitude 10 to 200 m.

Conservation status: Listed in CITES appendix 2.

Other Synonyms:

  • Chilita slevinii,
  • Bartschella albicans

Cultivation: It is  slow-growing, and not especially easy to grow.  Use pot with good drainage and a very porous mineral-based potting mix. Potted plants are quite wet-sensitive, especially in light of its small root system. Water sparingly during the growing season, keep very dry in winter.  Feed with a high potassium fertilizer  in summer.
Usually it is recommended to overwinter this plant in a bright and warm greenhouse with at least 8-10 C, but it has proved to be quite frost resistant (if kept dry
, it's hardy as low as -5 C).  Strong light is required for flowering.
Some plants will offset readily, and clumps can be produced in a very few years.
