== Etymology ==
The name means "narrow Cereus", referring to the typically narrow ribs.

== Description ==
'''Stenocereus''' is a diverse genus of columnar cacti ranging from shrubs to large tree-like forms.

* '''Habit''': Arborescent or shrubby; erect, branching, sometimes forming trunks; occasionally creeping (''S. eruca'').
* '''Growth form''': Often forming dense thickets (e.g. ''S. gummosus'').
* '''Stems''': Robust; usually strongly branched.
* '''Ribs''': Numerous; often tuberculate.
* '''Areoles''': Woolly.
* '''Spines''': Radial spines spreading; 1–4 central spines, often strong, sometimes flattened.
* '''Flowers''': Usually nocturnal; sometimes remaining open during the day; rarely diurnal.
* '''Flower shape''': Funnel-shaped to bell-shaped; often fragrant.
* '''Floral structures''': Scaly, often spiny pericarpel.
* '''Pollination''': Primarily by bats; also by hummingbirds, birds, bees, and occasionally butterflies.
* '''Fruits''': Globose to ovoid; often fleshy; usually edible; spines deciduous; generally lacking persistent perianth.
* '''Seeds''': Relatively large; obovoid; black; shiny; surface variable (smooth, tuberculate, pitted).
* '''Seed dispersal''': By bats, birds, lizards, and small mammals.

== Habitat ==
Occurs in a wide range of arid and semi-arid environments:

* deserts and sandy plains
* rocky slopes and canyons
* volcanic substrates
* xerophytic scrub (matorral)
* coastal regions

Altitude range: from sea level up to ~2120 m.

== Distribution ==
Americas:

* Mexico (widespread)
* United States (Arizona, California)
* Central America (Guatemala)
* Caribbean (Cuba, Puerto Rico, Dominican Republic)
* South America (Colombia, Venezuela)

== Taxonomy ==
A complex and partially unresolved genus.

Key points:

* Includes taxa formerly placed in ''Rathbunia'', ''Hertrichocereus'', ''Machaerocereus'', ''Lemaireocereus'', and others
* Morphological characters (silica bodies, pigments, triterpenoids) helped define the group (Gibson & Horak, 1978)
* Molecular studies (Terrazas 2000; Crozier 2005) support a core monophyletic clade
* Some species (e.g. ''S. aragonii'', ''S. eichlamii'') are misplaced and likely belong elsewhere
* Seed morphology studies confirm heterogeneity
* Nyffeler & Eggli (2010): genus not fully monophyletic as currently circumscribed
* Guiggi (2012): suggests transferring problematic taxa to ''Marshallocereus''

Despite these issues, the genus is maintained in a practical sense in Lodé (2015).

== Species ==
According to Joël Lodé (2015):

* [[Stenocereus alamosensis]]
* [[Stenocereus beneckei]]
* [[Stenocereus chacalapensis]]
* [[Stenocereus chrysocarpus]]
* [[Stenocereus eruca]]
* [[Stenocereus fimbriatus]]
* [[Stenocereus fricii]]
* [[Stenocereus griseus]]
* [[Stenocereus gummosus]]
* [[Stenocereus humilis]]
* [[Stenocereus kerberi]]
* [[Stenocereus martinezii]]
* [[Stenocereus montanus]]
* [[Stenocereus pruinosus]]
* [[Stenocereus queretaroensis]]
* [[Stenocereus quevedonis]]
* [[Stenocereus standleyi]]
* [[Stenocereus stellatus]]
* [[Stenocereus thurberi]]
* [[Stenocereus thurberi subsp. littoralis]]
* [[Stenocereus treleasei]]

== Notes ==
* One of the most ecologically and morphologically diverse cactus genera.
* Many species produce edible fruits important to local communities.
* Displays one of the widest pollination syndromes in Cactaceae.
* Includes anomalous taxa requiring further phylogenetic clarification.
* Central genus in the evolution of New World columnar cacti.
