Mammillaria fraileana is one of about 200 species of the genus Mammillaria from the cactus family Cactaceae. This species is native to Mexico and can be found along the east coast of the southern part of Baja California Peninsula in Desert Scrub communities. They tend to grow in non-calcareous dry granite-based soil but can also grow in rocky habitats, either in rock fissures or directly on top of the rock surface even without the presence of soil. Thus, the mineral composition of the rocks in their habitat directly influence their abundance. The habitat of Mammillaria fraileana is home to succulent flora and is particularly rich in local endemics. Currently, no major threats to the species are known to exist.
Mammillaria sphaerica, the longmamma nipple cactus or pale mammillaria is a species of flowering plant in the cactus family Cactaceae, native to south eastern Texas in the USA and north eastern Mexico, where it occurs in scattered patches at altitudes up to 1,000 m (3,300 ft).
