== Etymology ==
Named in honour of Pierre Rebut (1828–1898), a French cactus nurseryman.

== Description ==
'''Rebutia''' is a genus of small, low-growing cacti, often forming dense clusters.

* '''Habit''': Globose, depressed or shortly cylindrical; solitary or clumping.
* '''Areoles''': Rounded, ovate or elliptic.
* '''Spines''': Very variable; usually fine, short, often hair-like; typically white.
* '''Flowers''': Diurnal, funnel-shaped, relatively large compared to the body; yellow, orange, pink or red; usually self-fertile.
* '''Pericarpel''': Nearly glabrous (diagnostic for ''Rebutia'' s.s.).
* '''Pollination''': Mainly by bees.
* '''Fruits''': Small, globose; dry and papery when ripe; disintegrating.
* '''Seeds''': Numerous, black, shiny, ovate.
* '''Dispersal''': Myrmecochorous (by ants).

== Habitat ==
Occurs in high-altitude environments:

* rock crevices and rocky slopes
* highland grasslands and open areas

Altitude range: approximately 1200–3600 m.

Adapted to cold conditions, including snow and frost, typically under low humidity.

== Distribution ==
South America:

* Argentina (Catamarca, Jujuy, Salta, Tucumán)
* Bolivia (Tarija)

== Taxonomy ==
The genus is taxonomically complex and historically controversial.

Key points:

* Traditionally expanded to include ''Aylostera'', ''Sulcorebutia'' and ''Weingartia''
* Ritz et al. (2007): demonstrated that ''Rebutia'' sensu lato is polyphyletic
* Mosti et al. (2011): confirmed separation into distinct clades
* Hernández-Hernández et al. (2011): supported deep divergence between these groups

Current interpretation:

* '''Rebutia sensu stricto''' is a distinct lineage
* ''Aylostera'' (incl. ''Mediolobivia'' and others) represents a separate clade
* ''Sulcorebutia'' and ''Weingartia'' form another independent lineage

The genus is therefore treated here in a '''narrow sense (s.s.)'''.

== Species ==
Following Joël Lodé (2015), with a restricted species concept:

* [[Rebutia fabrisii]]
* [[Rebutia krainziana]]
* [[Rebutia marsoneri]]
* [[Rebutia minuscula]]
** [[Rebutia minuscula subsp. wessneriana]]
* [[Rebutia padcayensis]]

== Notes ==
* One of the most popular genera in cultivation due to abundant flowering.
* Shows extreme variability, especially within ''R. minuscula''.
* Historically over-expanded, leading to major taxonomic confusion.
* Current trend is toward splitting into multiple genera based on molecular data.
