== Etymology ==
The name Cephalocleistocactus means "Closed head cactus". This refers to the two most prominent features of the genus: the tubular, almost closed flowers (characteristic of ''Cleistocactus'') and the specialized flowering zone known as a pseudocephalium (''Cephalo'').

== Description ==
'''Cephalocleistocactus''' is a monotypic genus of columnar, shrubby cacti that branch primarily from the base. The stems feature low ribs marked by distinctive V-shaped grooves. The areoles bear finely setose (bristle-like) spines.

The flowers are diurnal and self-sterile. They are tubular, bright red, and emerge from a lateral pseudocephalium—a specialized area covered with long bristles. These flowers are adapted for pollination by hummingbirds. The fruits are reddish, containing small, shiny black seeds.

== Habitat ==
This genus is endemic to a very limited area in Bolivia. it grows at altitudes of approximately 2000 m.

== Distribution ==
* Bolivia (La Paz)

== Species ==
Currently, the genus is considered monospecific:

* [[Cephalocleistocactus chrysocephalus]]

== Notes ==
* The taxonomic position of this genus has been highly controversial. While some authors (Hunt & Taylor) included it within ''Cleistocactus'', others (Mottram, Anderson) maintained it as a separate genus.
* Joël Lodé recognizes it as a correct genus, supported by phylogenetic studies (Schlumpberger et al., 2012) which place it in a clade between ''Yungasocereus'' and ''Samaipaticereus''.
* Some researchers, such as R. Mottram, have suggested that the genus might have originated as a natural hybrid between ''Cleistocactus'' and ''Espostoa''.
