== Etymology ==
The name is derived from the Greek ''echinos'' (hedgehog) and ''mastos'' (breast/nipple), referring to the globose shape and the prominent tubercles of the plants.

== Description ==
'''Echinomastus''' consists of small, usually solitary cacti, globose to shortly cylindrical in habit.
* '''Stems:''' The ribs are low and arranged in spirals, divided into tubercles that feature a characteristic groove on the upper side.
* '''Areoles:''' Often possess nectariferous glands.
* '''Spines:''' Radial spines typically cover the epidermis; central spines may be absent in some species.
* '''Flowers:''' Diurnal and self-sterile, emerging from the apex at the top of the tubercles. They lack a significant floral tube and come in colors including white, yellow, pink, and magenta.
* '''Fruits and Seeds:''' The fruits are scaly, elongated, and dehisce at the base. Seeds are black, ovate to kidney-shaped, and finely papillose.

== Habitat ==
Echinomastus species grow in small, localized colonies within deserts or grasslands. [cite: 1003] They are found on varied substrates, frequently limestone, but also decomposed granite or volcanic lavas, at altitudes ranging from 200 m to 2400 m. [cite: 1003]

== Distribution ==
* '''Mexico:''' Chihuahua, Coahuila, Durango, San Luis Potosí, Zacatecas. [cite: 1003]
* '''USA:''' Arizona, California, Nevada, New Mexico, Texas, Utah. [cite: 1003]

== Species ==
Following Lodé (2015), the genus includes 8 recognized species, though he notes that several are taxonomically conflicting: [cite: 1003]

* [[Echinomastus durangensis]]
* [[Echinomastus erectocentrus]] (conflicting; possibly ''Sclerocactus'') [cite: 1003]
* [[Echinomastus gautii]] (incertae sedis) [cite: 1002, 1003]
* [[Echinomastus hispidus]]
* [[Echinomastus intertextus]]
* [[Echinomastus johnsonii]] (conflicting; possibly ''Sclerocactus'') [cite: 1003]
** [[Echinomastus johnsonii var. lutescens]]
* [[Echinomastus mariposensis]]
* [[Echinomastus unguispinus]]
** [[Echinomastus unguispinus subsp. laui]]
* [[Echinomastus warnockii]]

== Taxonomy ==
The genus remains a subject of debate. [cite: 1003] Molecular studies (Porter et al., 2000) show a close relationship with ''Ancistrocactus'' and ''Sclerocactus'', but only ''Toumeya'' is nested within ''Sclerocactus''. Lodé maintains ''Echinomastus'' as a separate genus to avoid making ''Sclerocactus'' more polyphyletic.
