Origin and Habitat: Mammillaria haageana is widespread and endemic to Mexico, occurring in the States of Puebla, Mexico, Veracruz, Morelos, Tlaxcala, and Oaxaca.
Altitude: 450-2600 metres above sea level.
Habitat and Ecology: The elevation range where this species occurs is wide, therefore it is found in many different vegetation types such as deciduous tropical forest, xerophyllous scrub, oak forest and secondary vegetation, juniper forest, pine forest, lava flows, and often in disturbed areas. It occurs in Cardonal-tetechera. The plants are commonly associated with nurse plants, but can also occur in bare areas. This species is locally threatened by the overcollection of wild populations for use as an ornamental.
