== Etymology ==
The genus is named in honor of George S. Hinton (1949–), a Mexican farmer and plant collector who discovered the plant in 1991.

== Description ==
'''Geohintonia''' is a monotypic genus consisting of a single species, ''G. mexicana''. It is a slow-growing, globose cactus.
* '''Stems''': Solitary, globose to somewhat columnar with age, reaching up to 10 cm in height and diameter. The epidermis is a distinct glaucous (grey-green) color and covered with a fine pruinose coating.
* '''Ribs''': Numerous (usually 18–20), well-defined, and acute.
* '''Areoles and Spines''': Areoles are small and initially woolly; spines are few, short, weak, and often deciduous (falling off with age).
* '''Flowers''': Diurnal and self-sterile, appearing at the apex. They are funnel-shaped and bright pink to magenta.
* '''Fruits''': Small, ovoid, and hidden in the apical wool. They are thin-walled and dehisce (open) irregularly.
* '''Seeds''': Small, black, and shiny with a finely tuberculate surface.

== Habitat ==
The genus is an extreme specialist, growing exclusively on vertical gypsum cliffs in a very restricted area. It is found at altitudes around 1100–1200 m, often growing alongside ''Aztekium hintonii''.

== Distribution ==
* '''Mexico''': Endemic to a single location in the state of Nuevo León (Galeana).

== Species ==
According to Lodé (2015), the genus consists of only one species:

* [[Geohintonia mexicana]] (Type species)

== Taxonomy ==
Molecular evidence confirms that ''Geohintonia'' is closely related to ''Aztekium'', but it is maintained as a separate genus due to its distinct morphological features, such as the absence of secondary ribs (intercostal furrows) and its unique seed structure.
