== Etymology ==
Named in honour of Werner Rauh (1913–2000), German botanist and expert on Peruvian flora.

== Description ==
'''Rauhocereus''' is a monotypic genus of shrubby columnar cacti forming clustered stems.

* '''Habit''': Shrubby, branching from the base; forming groups of erect stems.
* '''Stems''': Bluish-green, columnar.
* '''Ribs''': 5–6, tuberculate.
* '''Tubercles''': Distinctive, with faceted structure.
* '''Areoles''': Woolly.
* '''Spines''': Radial spines short, sometimes pectinate; 1–2 central spines longer and stronger.
* '''Flowers''': Nocturnal, bell-shaped to rotate, white; appearing near stem apex.
* '''Floral tube''': With small scales and brown, curly hairs.
* '''Pollination''': By bats (e.g. ''Anoura'' spp., ''Glossophaga soricina'').
* '''Fruits''': Ovoid, fleshy; raspberry-red to purple; longitudinally dehiscent from the base.
* '''Pulp''': Orange to scarlet.
* '''Seeds''': Small, elongated, black, shiny, finely pitted and striate.

== Habitat ==
Endemic to northern Peru:

* dry forests and dense shrub vegetation
* loamy soils

Altitude range: approximately 400–2500 m.

== Distribution ==
Peru:

* Amazonas
* Cajamarca
* Lambayeque

== Taxonomy ==
The genus is currently accepted and considered monophyletic.

Key points:

* Originally placed in Browningieae
* Nyffeler (2002): reassigned to Trichocereeae
* Applequist & Wallace (2002): supported revised placement
* Hernández-Hernández et al. (2011): confirmed monophyly
* Schlumpberger (2012): placed within the "Oreocereus clade"

Additional insights:

* Possible origin via hybridisation (Arakaki 2008)
* Closely related to ''Haageocereus'', ''Matucana'' and ''Oreocereus''

== Species ==
Currently one recognized species with a doubtful subspecies:

* [[Rauhocereus riosaniensis]]
** [[Rauhocereus riosaniensis subsp. jaenensis]]

== Notes ==
* A geographically restricted genus with a narrow distribution.
* Subspecies delimitation is uncertain and based mainly on spine characters.
* Represents part of a larger Andean cactus lineage (Oreocereus group).
