== Etymology ==
Named after the region of Samaipata in Bolivia, where the genus is endemic.

== Description ==
'''Samaipaticereus''' is a monotypic genus of tree-like columnar cacti.

* '''Habit''': Arborescent with a well-defined trunk; heavily branched.
* '''Stems''': Cylindrical, erect, dark green, not segmented.
* '''Ribs''': 4–6, well defined.
* '''Areoles''': Brown, well-spaced and regularly arranged.
* '''Spines''': Usually 5, short, subulate; one typically longer and directed downward.
* '''Flowers''': Nocturnal but remaining open during the following day; numerous, funnel-shaped, white.
* '''Floral tube''': Long, covered with scales, hairs and bristles.
* '''Pollination''': By bats (e.g. ''Anoura'' spp., ''Glossophaga soricina'') and hummingbirds.
* '''Fruits''': Globose, truncated, pink-red; longitudinally dehiscent; pulp bright orange.
* '''Seeds''': Ovate, dark brown, shiny, weakly sculptured.
* '''Reproduction''': Likely self-fertile.

== Habitat ==
Endemic to eastern Bolivian Andes:

* steep rocky slopes
* quebradas (valleys)

Altitude range: approximately 1150–2500 m.

== Distribution ==
Bolivia:

* Santa Cruz

== Taxonomy ==
The genus is accepted and relatively stable.

Key points:

* Nyffeler (2002): placement within Trichocereeae unresolved
* Lendel & Nyffeler (2006), Ritz et al. (2007): confirmed placement in Trichocereeae
* Arakaki (2008): suggested affinity with a broader South American clade
* Schlumpberger (2012): placed within a clade related to ''Cleistocactus'' and allies

Additional notes:

* Earlier suggestions of affinity with ''Harrisia'' are not supported by recent studies
* Morphology shows similarities with both Cereeae and Trichocereeae

== Species ==
Monotypic genus:

* [[Samaipaticereus corroanus]]

== Notes ==
* One of the few cactus genera that has remained taxonomically stable since its description.
* Displays a combination of traits linking different cactus lineages.
* Ecologically specialized to narrow habitats in Bolivia.
