== Etymology ==
The name means "dry fruit" (''siccus'' = dry, ''bacca'' = berry), referring to the characteristic dry fruits of the genus.

== Description ==
'''Siccobaccatus''' is a genus of columnar cacti with a distinctive cephalium and dry fruits.

* '''Habit''': Erect, usually solitary columnar stems.
* '''Stems''': Bluish; with a strongly woody vascular cylinder.
* '''Cephalium''': Continuous, deeply sunken, developing when stems exceed ~1 m; densely covered with white wool and long yellow to reddish bristles.
* '''Areoles''': Ovate, densely woolly.
* '''Spines''': Acicular, straight, well-developed especially at the base.
* '''Flowers''': Nocturnal, funnel- to bell-shaped, ivory-white; self-sterile.
* '''Pollination''': Primarily by bats (e.g. ''Monophyllus redmani'', ''Phyllonycteris poeyi'').
* '''Fruits''': Initially embedded in the cephalium; bluish, thin-walled, dry at maturity; basally dehiscent.
* '''Seeds''': Brown, very elongated, with cellular testa.
* '''Dispersal''': Likely anemochorous in some species (e.g. ''S. dolichospermaticus'').

== Habitat ==
Endemic to Brazilian dry regions:

* rocky substrates and limestone outcrops (Bambuí formation)
* caatinga vegetation and edges of dry tropical forests
* often forming dense populations

Altitude range: approximately 400–760 m.

Cephalia are consistently oriented toward the northwest.

== Distribution ==
Endemic to Brazil:

* Bahia
* Distrito Federal
* Goiás
* Minas Gerais
* Tocantins

== Taxonomy ==
The genus is currently accepted based on morphological and molecular evidence.

Key points:

* Originally segregated by Braun & Esteves (1990)
* Previously included in ''Micranthocereus'' (Ritter, 1979)
* Aona (2003): demonstrated polyphyly of ''Micranthocereus''
* Machado et al. (2006): placed ''Siccobaccatus'' as sister to ''Coleocephalocereus''
* Nyffeler & Eggli (2010): supported recognition as a separate genus

The genus is therefore considered distinct and monophyletic.

== Species ==
Currently three recognized species:

* [[Siccobaccatus dolichospermaticus]]
* [[Siccobaccatus estevesii]]
* [[Siccobaccatus insigniflorus]]

== Notes ==
* Distinguished by its dry fruits — unusual within Cactaceae.
* Formerly treated as part of ''Micranthocereus'', now clearly separate.
* Cephalium orientation may have ecological significance.
* Restricted distribution makes the genus of conservation interest.
