== Etymology ==
The name is derived from the Latin ''glandula'' (gland), referring to the prominent nectar-secreting glands (nectaries) located in the areoles.

== Description ==
'''Glandulicactus''' consists of globose to shortly cylindrical cacti, often becoming caespitose (forming clumps) with age.
* '''Stems''': Deeply ribbed, often with a bluish-green or dark green epidermis.
* '''Areoles''': Feature characteristic extrafloral nectaries (glands) located above the spine-bearing part of the areole.
* '''Spines''': Very strong and often hooked, particularly the central spines, which can be remarkably long and colorful (reddish or brownish).
* '''Flowers''': Diurnal and self-sterile, appearing near the apex. They are funnel-shaped and typically dark brownish-red or deep magenta.
* '''Fruits''': Globose to ovoid, slightly fleshy at first but becoming dry at maturity, usually covered with scales.
* '''Seeds''': Relatively large, black, and shiny with a finely pitted (foveolate) surface.

== Habitat ==
The genus grows in Chihuahuan Desert scrublands on rocky limestone or alluvial soils. They are found at altitudes between 600 m and 2400 m, often growing under the protection of nurse plants.

== Distribution ==
* '''Mexico''': Chihuahua, Coahuila, Durango, Nuevo León, San Luis Potosí, Tamaulipas, Zacatecas.
* '''USA''': New Mexico, Texas.

== Species ==
Following the classification of Lodé (2015), the genus includes 2 species and 2 subspecies:

* [[Glandulicactus mathssonii]]
* [[Glandulicactus uncinatus]]
** [[Glandulicactus uncinatus subsp. wrightii]]

== Taxonomy ==
While some modern classifications (e.g., Hunt) include these species within ''Sclerocactus'', molecular studies (Vázquez-Sánchez et al., 2013) suggest they are more closely related to ''Ancistrocactus''. Lodé keeps ''Glandulicactus'' separate based on its distinct extrafloral nectaries and specialized floral morphology.
