Melocactus praerupticola

A Turk's cap cactus described by Areces in 2000. GBIF now treats it as a subspecies of Melocactus lemairei from Hispaniola, with records only from the Dominican Republic. The name means 'cliff dweller'. Grow it like other Caribbean Melocactus: full sun, constant warmth, very sharp drainage, and never cold and wet.
