== Etymology ==
The name means "hairy ''Cereus''", referring to the characteristic hairy floral tube.

== Description ==
'''Trichocereus''' is a genus of columnar cacti ranging from creeping to massive tree-like forms.

* '''Habit''': Shrubby to arborescent; erect, decumbent or rarely pendulous; up to ~15 m tall.
* '''Stems''': Columnar, with straight ribs.
* '''Areoles''': Close-set, woolly.
* '''Spines''': Radial and central, highly variable; from fine acicular to strong subulate.
* '''Flowers''': Large, funnel-shaped; nocturnal or diurnal; white, yellow, red, pink or purple.
* '''Floral tube''': Long, thick, scaly, with dense hairs (usually dark).
* '''Pollination''': Extremely diverse — bees, moths, bats, birds and insects.
* '''Fruits''': Globose, thick-walled; hairy but spineless; pulp white.
* '''Seeds''': Small, dark brown to black, pitted; dispersal by ants, birds and bats.

== Habitat ==
Extremely wide ecological range:

* deserts, valleys, slopes, canyons and plains
* rocky, sandy and saline soils
* xerophytic shrublands

Altitude range: ~25–4300 m.

Some species tolerate frost and snow.

== Distribution ==
South America:

* Argentina
* Bolivia
* Chile
* Peru
* Ecuador
* Paraguay

== Taxonomy ==
One of the most complex genera in Cactaceae.

Key points:

* Historically separated from ''Echinopsis'' based on floral morphology
* Later merged into ''Echinopsis'' sensu lato (Hunt et al.)
* Molecular studies show that ''Echinopsis s.l.'' is polyphyletic
* Strong links with ''Lobivia'', ''Soehrensia'' and related groups

Current interpretation:

* '''Trichocereus sensu stricto''' is accepted
* ''Helianthocereus'' is included within it
* Relationships remain partially unresolved

== Notes ==
* One of the most taxonomically debated cactus genera.
* Strong morphological convergence complicates classification.
* Molecular data only partially resolves relationships.
* Closely linked to ''Echinopsis'', ''Lobivia'' and ''Soehrensia''.
* Species limits remain fluid and subject to revision.
