== Etymology ==
Named after Yavi, a locality in Jujuy Province, Argentina, near the Bolivian border.

== Description ==
'''Yavia''' is a monotypic genus of extremely small, geophytic cacti adapted to high-altitude desert environments.

* '''Habit''': Solitary; geophytic; mostly subterranean.
* '''Size''': Up to ~3 cm in diameter.
* '''Roots''': Long napiform root.
* '''Stems''': Depressed; apex umbilicate; largely hidden below ground.
* '''Ribs''': Numerous (up to ~40), poorly defined.
* '''Tubercles''': Low, barely distinguishable.
* '''Areoles''': Very small.
* '''Spines''': Tiny, pectinate, inconspicuous.
* '''Flowers''': Diurnal; apical; bell-shaped.
* '''Flower color''': White to pink.
* '''Reproduction''': Self-sterile.
* '''Pollination''': By insects.
* '''Fruits''': Turbinate; sunken into the plant; basally dehiscent; perianth remains deciduous.
* '''Seeds''': Few (4–25 per fruit); dark brown to black; finely tuberculate; prominent hilum.
* '''Special trait''': Cryptic fruiting—fruits remain hidden within the plant body.

== Habitat ==
Occurs in extreme high-altitude desert conditions:

* rocky slopes with minimal vegetation
* friable sedimentary and metamorphic rocks
* full sun exposure; occasionally partial shade

Altitude range: approximately 3600–3800 m.

== Distribution ==
South America:

* Argentina (Jujuy)
* Bolivia (Santa Cruz)

Not strictly endemic to Argentina, as previously thought.

== Taxonomy ==
A highly distinct and phylogenetically important genus.

Key points:

* Described by Kiesling & Piltz (2001)
* Placed within Notocacteae by multiple molecular studies (Nyffeler 2002; Ritz et al. 2007; Crozier 2005)
* Closely related to ''Neowerdermannia'' and ''Rimacactus''
* Clearly separated from ''Eriosyce'' sensu lato
* Not related to ''Blossfeldia'' or ''Cintia'' despite superficial similarities
* Nyffeler & Eggli (2010): confirmed its isolated lineage within Notocacteae

The genus is accepted as distinct in Lodé (2015).

== Species ==
Monotypic genus:

* [[Yavia cryptocarpa]]

== Notes ==
* One of the most cryptic and well-camouflaged cacti.
* Geophytic habit provides protection against extreme environmental conditions.
* Fruit remains hidden inside the plant—an unusual reproductive strategy.
* Strong adaptation to high-altitude desert ecosystems.
* Represents a highly specialized and isolated evolutionary lineage.
