== Etymology ==
The genus is named in honour of Pierre Josef Braun (1959–), German botanist and specialist of Brazilian cacti.

== Description ==
'''Pierrebraunia''' is a small genus of usually solitary cacti, ranging from subglobose to elongated or weakly columnar forms.

* '''Habit''': Solitary, sometimes weakly branched (''P. brauniorum''); erect or slightly bent.
* '''Stems''': With 10–17 ribs (reduced to 4–5 in ''P. brauniorum''); not constricted.
* '''Epidermis''': Finely granular in ''P. brauniorum''.
* '''Cephalium''': Absent; flowering areoles may be woolly.
* '''Spines''': Acicular, thin and fragile.
* '''Flowers''': Diurnal, tubular, apical; pink to magenta; self-sterile; pollinated by hummingbirds.
* '''Fruits''': Globose to ovoid, waxy; pale pink to wine-red; containing liquid pulp.
* '''Seeds''': Black, matte; slightly striate and foveolate (smooth in ''P. brauniorum'').

== Habitat ==
The genus grows in dry, rocky environments:

* cliffs and steep slopes
* rock crevices and shallow soils
* open, sun-exposed habitats

Often associated with grasses, bromeliads, orchids, and other cacti.

Altitude range: около 1000 m.

== Distribution ==
* '''Brazil''':
* Bahia
* Minas Gerais

== Taxonomy ==
The genus ''Pierrebraunia'' was established in 1997 by Esteves Pereira.

Its taxonomic position is highly uncertain:

* ''Pierrebraunia bahiensis'' was previously placed in ''Floribunda'' and later in ''Arrojadoa''
* It differs from ''Arrojadoa'' by lacking a cephalium, despite similar bird-pollinated flowers
* Molecular data suggest affinities with ''Lagenosocereus''

''Pierrebraunia brauniorum'' is even more problematic:

* possibly related to ''Pilosocereus''
* or a natural hybrid involving ''Arrojadoa'' or ''Micranthocereus''

These taxa may represent cases of '''reticulate evolution'''.

The genus is therefore considered '''artificial and probably non-monophyletic''', but provisionally maintained.

== Species ==
Following Joël Lodé (2015):

* [[Pierrebraunia bahiensis]]
* [[Pierrebraunia brauniorum]]

== Notes ==
* The genus likely represents a temporary taxonomic solution.
* Both species may eventually be reassigned to other genera.
* Pollination shift (bat → hummingbird) is suggested in evolutionary scenarios.
* A good example of complex evolution in Brazilian cacti.
