Geohintonia is a genus with one species, Geohintonia mexicana, a slow-growing, globose cactus from gypsum hills in Nuevo León, Mexico. It is grown by collectors and needs very sharp drainage and bright light.
Geohintonia mexicana (discovered in 1992) is a species of cacti, the only species in the genus Geohintonia. This genus is named after its discoverer George S. Hinton. As its specific epithet suggests, the plant is found in Mexico (Nuevo León), where it grows on gypsum hills near Galeana.
The plants grow exclusively in Mexico in the state of Nuevo León on gypsum hills at 1200 to 1350 meters. Aztekium hintonii and Selaginella gypsophila can also be found at the site. It is thought that the species may have arisen from a natural hybrid with Aztekium hintonii as one parent.
