Origin and Habitat: Central and northern Bahia, eastern Brazil.
Altitude: 450-800 metres above sea level.
Habitat: This species has a small range and is restricted to low-lying outcrops of limestone. The species occurs in subpopulations of a few hundred individuals, however, in some there are millions. Habitat loss for agriculture is a major threat, the vegetation gets destroyed when the surrounding caatinga forest is cleared for cultivation causing a continuing decline of the natural populations. Also, the change in the surrounding vegetation has an impact on the outcrops were the species grows, making them prone to invasive species.

Description: Melocactus azureus is one of most desirable of the Brazilian melocacti because of its striking frosty blue epidermis, this plant has a reputation for being more difficult to cultivate than most.

Flowers: Small 15-23 mm long 4-11 mm in diameter pink to magenta, with approx. 25 perianth-segments visible from above.
