== Etymology ==
The name derives from "Quiabento", a vernacular term used in Brazil for plants of this genus.

== Description ==
'''Quiabentia''' is a genus of shrubby to tree-like cacti with leafy, cylindrical stems.

* '''Habit''': Shrubs (''Q. zehntneri'') or small trees (''Q. verticillata''), densely branched, often with verticillate branching.
* '''Stems''': Cylindrical, succulent.
* '''Leaves''': Fleshy, flattened, ovate to spatulate, persistent or seasonal.
* '''Areoles''': Bearing glochids and numerous spines.
* '''Flowers''': Diurnal, solitary, sessile, rotate; pink, red or pale; self-sterile.
* '''Fruits''': Elongated, fleshy or dry.
* '''Seeds''': Large, flattened, with a sclerotic aril.

== Habitat ==
The genus grows in seasonally dry forests, shrublands, and rocky or sandy environments, including limestone outcrops and inselbergs. It is also found in the Brazilian caatinga.

Altitude range: from sea level up to about 2200 m.

== Distribution ==
* '''South America''':
Argentina (Chaco, Formosa, Jujuy, Salta),
Bolivia (Cochabamba, Chuquisaca, Santa Cruz, Tarija),
Brazil (Bahia, Minas Gerais),
Paraguay (Alto Paraguay, Boquerón, Presidente Hayes)

== Taxonomy ==
The genus ''Quiabentia'' was established by Britton & Rose (1923).

It is closely related to ''Pereskiopsis'' and belongs to a clade of cacti with cylindrical stems within Opuntioideae, including ''Austrocylindropuntia'', ''Corynopuntia'', ''Grusonia'', ''Micropuntia'', and ''Tephrocactus''.

Although superficially similar to ''Pereskia'', its placement within Opuntioideae is supported by the presence of glochids and seed structure.

Molecular studies (Griffith & Porter 2009) confirm its distinct phylogenetic position.

== Species ==
Following the classification of Joël Lodé (2015).

* [[Quiabentia verticillata]]
* [[Quiabentia zehntneri]]

== Notes ==
* The genus contains only two species with a strong geographic disjunction.
* ''Quiabentia verticillata'' occurs in southern regions, while ''Q. zehntneri'' is restricted to eastern Brazil.
* Seed dispersal may involve large mammals such as tapirs.
