  • Geographic Distribution: Jalisco, Mexico. Altitude 1.800 to 2.400 m
  • Comments: In culture, it needs good drainage (up to 50% grit content). Water should be carefully applied, as fits this cliff-dwelling species, and not too large a pot. This rarely found species is slow growing, but rewards the patient grower with displays of small dark pink flowers. Winter rest is important to stimulate flowering.
