Mexican rare cacti

Geohintonia mexicana and Aztekium hintonii are two remarkable cactus species, both endemic to Mexico and growing in gypsum-rich soil. Geohintonia mexicana is characterized by its globular, often solitary shape, with well-marked ribs and spaced areoles. Its spines are short and rigid, and generally brown or white in color. It is found mainly in arid, rocky areas, notably in the state of San Luis Potosí. In summer, it produces beautiful white or pale yellow flowers that brighten up its silhouette.

On the other hand, Aztekium hintonii is smaller and also adopts a rounded shape, but stands out for its unique texture. Its ribs are well-defined and its areoles are covered with fine, dense spines. These two species illustrate the richness of Mexican succulent flora, each with its particular adaptations to a demanding habitat.
