== Etymology ==
The name is derived from the Latin ''mammilla'' (nipple or teat), referring to the characteristic tubercles (mammillae) that cover the plant's body instead of ribs.

== Description ==
'''Mammillaria''' is the most diverse and widely cultivated genus of cacti. It is defined by several unique morphological features that distinguish it from all other members of the tribe '''Cacteae'''.

=== Morphological Key Features ===
* '''Tubercles (Mammillae):''' The plant body is covered in spirally arranged tubercles rather than ribs. These are organized in mathematical patterns (Fibonacci sequences).
* '''Dimorphic Areoles:''' The areole is split into two distinct parts:
** '''The Apex (Tip):''' Bears the spines.
** '''The Axil (Base):''' Located between the tubercles, this is where flowers, fruits, and new offsets (branches) emerge.
* '''Floral Ring:''' Flowers typically appear in a circular "crown" around the previous year's growth, rather than from the very top of the plant.
* '''Sap:''' Species are often categorized by their sap:
** '''Hydrochyle:''' With watery sap (mostly desert species).
** '''Galactochyle:''' With milky latex (often more robust, mountain species).

== Habitat and Ecology ==
Mammillarias are found in a vast range of environments—from coastal plains and limestone deserts to high-altitude pine forests. They have evolved incredible survival mechanisms, such as dense wool or hooked spines for protection and camouflage.

== Distribution ==
* '''Primary Center of Diversity:''' Mexico.
* '''Extending to:''' Southwestern USA, Caribbean, Guatemala, Honduras, Colombia, and Venezuela.

== Classification by Joël Lodé ==
Following the taxonomy of '''Joël Lodé (2015)''', the genus is maintained in a broad sense but strictly organized. Lodé recognizes:
* '''160 Species'''
* '''149 Subspecies'''

The genus is further divided into subgenera and sections based on seed morphology and floral structure:
# '''Subgenus Mammillaria''' (The largest group)
# '''Subgenus Phellosperma'''
# '''Subgenus Dolichothele'''
# '''Subgenus Cochemiea''' (Partial inclusion)

== Species List ==
''Note: Due to the large number of taxa, the species list is organized alphabetically and by sub-groups. See the sub-pages for detailed descriptions of each species.''

== Taxonomy ==
Lodé rejects the extreme splitting of the genus but also excludes certain groups like ''Mammilloydia'' and ''Cochemiea'' (partially) based on modern molecular phylogenetics which show they are distinct lineages. His work in Volume 2 (pp. 6-111) remains the most comprehensive modern treatment of the genus.
