== Etymology ==
Named in honour of Karl Friedrich (Carlos) Reiche (1860–1929), German botanist specializing in Chilean flora.

== Description ==
'''Reicheocactus''' is a genus of small, geophytic or semi-geophytic cacti with tuberous roots.

* '''Habit''': Small, low-growing; usually solitary, occasionally branching after damage.
* '''Stems''': Cylindrical, depressed at the apex; strongly constricted above a tuberous root.
* '''Roots''': Tuberous; plants may retract or disappear during dry periods (geophytic behaviour).
* '''Ribs''': Numerous (24–40), low and poorly defined.
* '''Areoles''': Elongated, on small tubercles.
* '''Spines''': Very small, soft, pectinate.
* '''Flowers''': Diurnal, lateral, shortly tubular to campanulate; pale silvery-yellow to yellow-orange with brownish tepals.
* '''Floral tube''': Covered with woolly hairs.
* '''Pollination''': By insects.
* '''Fruits''': Elongated, purplish, with hairy scales; longitudinally dehiscent.
* '''Seeds''': Numerous (up to ~400 per fruit), black, warty, subglobose to elongated, with mucilage remnants.

== Habitat ==
Endemic to northwestern Argentina:

* rocky habitats in full sun
* often growing among stones
* includes true geophytic species

Altitude range: approximately 1200–3050 m.

== Distribution ==
Argentina:

* Catamarca
* San Juan

== Taxonomy ==
The genus has a complex and historically controversial classification.

Key points:

* Originally described as ''Echinocactus famatimensis'' (Spegazzini, 1921)
* Later transferred to ''Rebutia'' and ''Lobivia''
* Backeberg (1942): established ''Reicheocactus''
* Later included in ''Echinopsis'' (Anderson 2001; Hunt 2006)
* Kiesling (2001): discussed nomenclatural issues
* Schlumpberger et al. (2012): molecular data supports recognition as a distinct genus

Current interpretation:

* Forms a basal lineage within the ''Echinopsis'' complex
* Now generally accepted as a valid genus

== Species ==
Currently two recognized species:

* [[Reicheocactus bonnieae]]
* [[Reicheocactus pseudoreicheanus]]

== Notes ==
* One of the few geophytic cacti in the Cactaceae.
* Exhibits seasonal stem reduction similar to ''Pterocactus''.
* Historically misclassified due to morphological similarity with ''Echinopsis'' and ''Lobivia''.
* Molecular evidence has clarified its distinct status.
