* Dominican Republic
* United States (Florida)

== Taxonomy ==
The genus shows a complex evolutionary history involving hybridization.

Key points:

* Described by Lemaire (1862)
* Often placed within or near ''Opuntia'' sensu stricto
* High levels of polyploidy (Negrón-Ortiz, 2007)
* Evidence of reticulate evolution (Griffith, 2005)
* Nuclear and chloroplast DNA give conflicting phylogenetic signals
* Nyffeler & Eggli (2010): suggested inclusion within ''Opuntia''
* Majure et al. (2012): confirmed ''Consolea'' as monophyletic and distinct

The genus is therefore retained as separate following Lodé (2015).

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

* [[Consolea corallicola]]
* [[Consolea falcata]]
* [[Consolea macracantha]]
* [[Consolea millspaughii]]
** [[Consolea millspaughii subsp. caymanensis]]
* [[Consolea moniliformis]]
** [[Consolea moniliformis subsp. guantanamana]]
* [[Consolea nashii]]
** [[Consolea nashii subsp. gibarensis]]
* [[Consolea picardae]]
* [[Consolea rubescens]]
* [[Consolea spinosissima]]

== Notes ==

* A predominantly Caribbean lineage with strong ecological specialization.
* High polyploidy levels likely contributed to diversification.
* Displays reticulate evolution, explaining conflicting molecular results.
* Morphologically distinct from ''Opuntia'' and ''Nopalea'', especially in growth architecture.

* '''Habit''': Epiphytic, epilithic, or terrestrial; climbing or pendulous.
* '''Stems''': Long, slender; often exceeding 5 m; finely ribbed; with aerial roots.
* '''Branching''': Dense; stems often sprawling or climbing on vegetation.
* '''Areoles''': With short hairs.
* '''Spines''': Small; setose, hairy, or absent.
* '''Flowers''': Nocturnal; very large; self-sterile; intensely fragrant.
* '''Flower size''': Up to ~40 cm long and 20 cm in diameter.
* '''Flower shape''': Funnel-shaped.
* '''Flower color''': Inner tepals white; outer tepals yellow, pink, or brownish.
* '''Floral structures''': Long floral tube with scales, hairs, bristles or spines.
* '''Pollination''': By bats and sphingid moths.
* '''Fruits''': Globose to oblong; fleshy; usually red; edible; often with persistent spines.
* '''Seeds''': Ovoid to kidney-shaped; black; glossy; covered with mucilage.

== Habitat ==
Occurs in a wide range of tropical environments:

* climbing on vegetation
* epiphytic in trees
* near rivers and wetlands
* mangroves and swampy areas

Altitude range: from sea level up to ~2400 m.

== Distribution ==
Widespread in the Neotropics:

* Mexico
* Central America

One of the most broadly distributed epiphytic cactus genera.

== Taxonomy ==
A complex and historically fluid genus.

Key points:

* Traditionally included several genera (''Cryptocereus'', ''Deamia'', ''Strophocactus'', ''Salmdyckia'')
* Bauer (2003): redefined boundaries, transferring several taxa
* ''Strophocactus'' re-established as separate genus
* ''Salmdyckia'' transferred to ''Hylocereus''
* ''Nyctocereus chontalensis'' briefly included, later reassigned to ''Strophocactus''
* Molecular studies (Nyffeler & Eggli 2010; Bárcenas et al. 2011) support a monophyletic core (''Selenicereus'' sensu stricto)

The genus is accepted as distinct in Lodé (2015).

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

* [[Selenicereus atropilosus]]
* [[Selenicereus dorschianus]]
* [[Selenicereus grandiflorus]]

== Taxonomy ==
A complex and debated genus.

Key points:

* Separated from ''Rhipsalis'' based on floral and fruit morphology
* Belongs to Hylocereinae, not Rhipsalideae
* Often merged into ''Disocactus'' by some authors (Kimnach)
* Retained as distinct by Barthlott and the IOS working group
* Inclusion of ''Wittia amazónica'' (now ''Pseudorhipsalis amazónica'') clarified its limits
* Modern phylogenetic studies confirm its placement within Hylocereeae, but relationships remain complex :contentReference[oaicite:1]{index=1}

The genus is accepted as distinct in Lodé (2015).

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

* [[Pseudorhipsalis acuminata]]
* [[Pseudorhipsalis alata]]
* [[Pseudorhipsalis amazónica]]
* [[Pseudorhipsalis himantoclada]]
* [[Pseudorhipsalis lankesteri]]
* [[Pseudorhipsalis ramulosa]]

== Notes ==
* Strong morphological convergence with ''Rhipsalis''.

* '''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).

* '''Seeds''': Large; brown; smooth; glossy.
* '''Seed dispersal''': Likely by birds (ornithochory).

== Habitat ==
Occurs in tropical dry forest ecosystems:

* deciduous dry forests
* lowland environments near sea level
* growing initially under nurse plants (nurse effect / nodricism)
* later emerging above surrounding vegetation

Often associated with genera such as ''Acanthocereus'', ''Hylocereus'', ''Mammillaria'', ''Opuntia'', ''Selenicereus'', and ''Stenocereus''.

Altitude range: near sea level.

== Distribution ==
Mexico:

* Campeche
* Chiapas
* Yucatán

Endemic to southern Mexico.

== Taxonomy ==
A genus separated from ''Pachycereus'' based on morphological and molecular evidence.

Key points:

* Originally described as ''Pachycereus gaumeri'' (Britton & Rose, 1920)
* Later segregated into distinct genera (e.g. ''Backebergia'', ''Lophocereus'', ''Pterocereus'')
* Often retained within ''Pachycereus'' in broader classifications (Anderson, Hunt et al.)
* Molecular studies (Arias et al., 2003) support separation
* Arias & Terrazas (2009): confirmed status and recognized subspecies

The genus is accepted as distinct in Lodé (2015).

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

* [[Pterocereus gaumeri]]
* [[Pterocereus gaumeri subsp. foetidus]]

== Notes ==
* Characterized by very thin, wing-like ribs.
* Emits unpleasant odour to attract bat pollinators.

}}

== Etymology ==
The name means "false Acanthocereus", referring to its superficial resemblance to that genus.

== Description ==
'''Pseudoacanthocereus''' is a genus of low-growing, shrubby cacti with slender, climbing stems.

* '''Habit''': Bushy; strongly branched; initially erect, later arching or pendulous.
* '''Stems''': Slender; with 2–8 ribs; well-defined but variable.
* '''Areoles''': Small; brownish.
* '''Spines''': Short; acicular.
* '''Flowers''': Nocturnal; self-sterile; strongly fragrant.
* '''Flower shape''': Funnel-shaped with long floral tube.
* '''Flower color''': White.
* '''Pollination''': By sphingid moths (Sphingidae).
* '''Fruits''': Globose; fleshy; indehiscent; pale yellow; strongly fragrant (pineapple-like).
* '''Fruit traits''': Spines deciduous at maturity.
* '''Seeds''': Large; flattened; pale brown; slightly striate.
* '''Seed dispersal''': By animals, including peccaries (e.g. ''Tayassu pecari'').

== Habitat ==
Occurs in tropical dry environments:

* caatinga (Brazil)
* subtropical dry forests
* scrublands
* often growing in shade
* supported by surrounding vegetation

Altitude range: approximately 300–400 m.

== Distribution ==
South America:

* Brazil (Bahia, Minas Gerais, Sergipe)
* Colombia
* Venezuela (Falcón, Lara, Zulia)

Notably disjunct distribution (~4000 km between populations).

== Taxonomy ==
A small and poorly understood genus with notable disjunction.

Key points:

* Described by Ritter (1979) from ''Acanthocereus''-like taxa
* Distinguished mainly by fruit and seed morphology
* Accepted by Hunt & Taylor (1992) and Anderson (2001)
* Two geographically distant species suggest possible hidden diversity or historical distribution

The genus is accepted as distinct in Lodé (2015).

⚠️ Modern molecular studies (e.g. Korotkova et al., 2017) suggest that the species of this genus are closely related to ''Strophocactus'' and have been transferred there in recent classifications :contentReference[oaicite:0]{index=0}.
However, this treatment is not followed here.

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

* [[Pseudoacanthocereus brasiliensis]]
* [[Pseudoacanthocereus sicariguensis]]

== Notes ==
* Must not be confused with ''Pseudoacanthocereus'' subgenus (Sánchez-Mejorada, 1974) within ''Acanthocereus''.
* Shows strong morphological similarity to ''Acanthocereus'', but differs in reproductive traits.
* Displays one of the most striking disjunctions in Cactaceae.
* Likely requires further molecular study to confirm evolutionary relationships.
* Represents a transitional morphological type between climbing and shrubby cacti.

== Etymology ==
Named in honour of Dr. Ira Loren Wiggins (1899–1987), American botanist specialized in the flora of Baja California.

== Description ==
'''Wigginsia''' is a genus of low-growing, globose cacti characterized by a distinctive pseudocephalium.

* '''Habit''': Usually solitary; sometimes forming small groups.
* '''Stems''': Globose to depressed; low-growing.
* '''Roots''': Fibrous to moderately thickened.
* '''Ribs''': Acute, well-defined, often deeply incised.
* '''Areoles''': Widely spaced; densely woolly near the apex, becoming naked with age.
* '''Spines''': Few; short, sturdy, subulate.
* '''Pseudocephalium''': Formed at the apex from densely woolly flowering areoles.
* '''Flowers''': Diurnal, often remaining open for extended periods; self-fertile.
* '''Flower shape''': Funnel-shaped to nearly rotate.
* '''Flower color''': Pale yellow.
* '''Reproductive traits''': Sensitive stamens; red stigma lobes.
* '''Floral structures''': Pericarpel and tube with woolly scales.
* '''Pollination''': Mainly by bees (multiple families including Andrenidae, Apidae, Halictidae, Megachilidae).
* '''Fruits''': Soft, elongated, somewhat flattened; pink to red; emerging from pseudocephalium; without persistent floral remnants.
* '''Seeds''': Large, bell-shaped, black; finely tuberculate; with a wrinkled brown aril.
* '''Seed dispersal''': Primarily myrmecochory (ants), also hydrochory (rainwater).

== Habitat ==
Typically found in open grassland ecosystems:

* pampa vegetation
* rocky outcrops and hills
* gravelly soils among stones
* among grasses and shrubs
* full sun or partial shade

Altitude range: from ~25 m up to 2600 m (notably in Bolivia).

== Distribution ==
South America:

* Argentina (Buenos Aires, Catamarca, Córdoba, Corrientes, Entre Ríos, La Pampa)
* Bolivia (Chuquisaca)
* Brazil (Rio Grande do Sul)
* Colombia (Cundinamarca)
* Uruguay (widespread)

== Taxonomy ==
A historically complex genus with multiple reclassifications.

Key points:

* Originates from the invalid genus ''Malacocarpus'' (Salm-Dyck, 1849)
* Renamed as ''Wigginsia'' by Porter (1964)
* Frequently included in ''Notocactus'' or merged into ''Parodia'' (Hunt & Taylor, Anderson, Hunt et al.)
* Machado (2006, 2007) demonstrated polyphyly in ''Parodia'' sensu lato
* Supports segregation into several genera including ''Wigginsia''
* Molecular and morphological data support its recognition as a distinct lineage

A notable biogeographical anomaly is ''Wigginsia vorwerkiana'' in Colombia, far disjunct (~3000 km) from the main distribution.

The genus is accepted as valid in Lodé (2015).

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

* [[Wigginsia arechavaletae]]
* [[Wigginsia erinacea]]
* [[Wigginsia horstii]]
* [[Wigginsia langsdorfii]]
* [[Wigginsia sellowii]]
* [[Wigginsia tephracantha]]
* [[Wigginsia turbinata]]
* [[Wigginsia turbinata subsp. calvescens]]
* [[Wigginsia vorwerkiana]]

== Notes ==
* Characterized by the formation of a pseudocephalium, unusual within Notocactinae.
* Strong ecological adaptation to grassland (pampa) environments.
* Seed dispersal heavily reliant on ants.
* Taxonomically controversial due to historical inclusion in ''Parodia''.
* Displays significant geographic disjunction within the genus.

}}

== Etymology ==
The name means "crevice cactus", referring to its growth in rock cracks and crevices.

== Description ==
'''Rimacactus''' is a monotypic genus of extremely small, cryptic cacti adapted to hyper-arid environments.

* '''Habit''': Solitary; globose to flattened; extremely small in habitat.
* '''Size''': Typically 0.5–1 cm in diameter in the wild; larger in cultivation.
* '''Roots''': Napiform (turnip-shaped), adapted for water storage.
* '''Stems''': Almost completely hidden by dense trichomes.
* '''Areoles''': Bearing long, white hairs obscuring the epidermis.
* '''Spines''': Few, straight, relatively short.
* '''Leaves''': Reported in seedlings, possibly representing early tubercles.
* '''Flowers''': Diurnal but remaining open at night; disproportionately large relative to the plant; funnel-shaped.
* '''Flower color''': Sulphur yellow with brownish outer tepals.
* '''Flower longevity''': Very long-lasting (up to ~11 days).
* '''Pollination''': Likely by small hymenopterans; extended flowering increases chances in pollinator-scarce environments.
* '''Fruits''': Elongated, angled, hollow; dry at maturity; pinkish; persistent.
* '''Seeds''': Black, shiny, pear-shaped; granular surface; sunken hilum.
* '''Seed dispersal''': Likely myrmecochory (ant-mediated), possibly also wind-assisted.

== Habitat ==
Occurs in one of the most extreme desert environments:

* rock crevices and fissures
* hyper-arid coastal desert zones
* areas influenced by fog (camanchaca)

Altitude range: approximately 400–1000 m.

== Distribution ==
Chile:

* Antofagasta

Endemic to a very restricted area (~10 km²).

== Taxonomy ==
A highly distinctive and historically controversial genus.

Key points:

* Discovered by Alfred Lau (1971)
* Initially associated with ''Eriosyce'' sensu lato (Nyffeler & Eggli, 1997)
* Separated as a distinct genus by Mottram (2001)
* Later transferred to ''Islaya'' by Faúndez & Kiesling (2007), but not retained in Lodé
* Molecular studies (Nyffeler & Eggli, 2010) confirm an isolated lineage
* Closely related to ''Neowerdermannia'' and ''Yavia''
* Morphologically and anatomically distinct from ''Eriosyce'', ''Islaya'', and ''Matucana''

Experimental hybridization showed compatibility with ''Oroya peruviana'', but not with ''Copiapoa'', ''Eriosyce'', or ''Matucana''.

The genus is therefore accepted as distinct in Lodé (2015).

== Species ==
Monotypic genus:

* [[Rimacactus laui]]

== Notes ==
* One of the smallest cacti in habitat.
* Extremely cryptic and easily overlooked in the wild.
* Adapted to ultra-arid conditions with fog-dependent moisture.
* Long-lived flowers compensate for scarce pollinators.
* Represents an isolated evolutionary lineage within Notocactinae.

}}

== Etymology ==
Named after the Yungas region (La Paz, Bolivia), where the genus was first discovered.

== Description ==
'''Yungasocereus''' is a monotypic genus of columnar cacti with uncertain phylogenetic placement.

* '''Habit''': Shrubby to tree-like; branching; columnar; up to ~4–5 m tall.
* '''Stems''': Erect, with weakly defined ribs.
* '''Ribs''': 6–10, straight, slightly tuberculate; with transverse grooves above areoles.
* '''Areoles''': Close-set.
* '''Spines''': 4–12, short, aciculate; radials and centrals not clearly differentiated.
* '''Flowers''': Nocturnal, remaining open during the day; small, narrowly funnel-shaped, slightly zygomorphic, white.
* '''Floral tube''': With imbricated, woolly scales.
* '''Pollination''': By bats.
* '''Fruits''': Small, broadened at the base; with numerous fleshy scales; partially retaining floral remains.
* '''Seeds''': Elongated, shiny, dark brown to black.

== Habitat ==
Endemic to the Bolivian Yungas:

* humid tropical montane forests
* warm, moist environments

Altitude range: approximately 1450–2550 m.

== Distribution ==
Bolivia:

* La Paz

== Taxonomy ==
The genus has a highly uncertain and debated placement.

Key points:

* Originally described as ''Samaipaticereus inquisivensis'' (Cárdenas, 1957)
* Transferred to ''Yungasocereus'' by Ritter (1980)
* Temporarily included in ''Haageocereus'' (Hunt & Taylor)
* Later restored as a separate genus

Molecular insights:

* Arakaki (2008): places it within or near ''Weberbauerocereus''
* Schlumpberger (2012): includes it in a "Cleistocactus clade"
* Franck (2012): groups it with ''Cleistocactus'' and ''Samaipaticereus''

Interpretation:

* Possibly derived from reticulate evolution
* Phylogenetic position remains unresolved

The genus is therefore considered '''provisionally accepted'''.

== Species ==
Monotypic genus:

* [[Yungasocereus inquisivensis]]

== Notes ==
* One of the least clearly resolved genera in Trichocereinae.
* Shows affinities with multiple genera (''Weberbauerocereus'', ''Cleistocactus'', ''Samaipaticereus'').
* May represent a lineage shaped by hybridisation.
* Restricted to a very specific ecological zone (Yungas forests).

* Arakaki (2002–2008): demonstrated monophyly and clarified relationships
* Closely related to ''Cleistocactus'' and ''Yungasocereus''
* Schlumpberger (2012): placed within a "Cleistocactus clade" including
''Vatricania'', ''Samaipaticereus'', ''Weberbauerocereus'' and others

Additional notes:

* ''Weberbauerocereus'' was long thought endemic to Peru
* Discovery of ''W. madidiensis'' (2010) extended distribution into Bolivia
* Several historical misidentifications (e.g. confusion with ''Haageocereus fascicularis'')

The genus is currently accepted as distinct.

The genus honours Louis Vatrican (1904–2007), Monegasque botanist and long-time director of the Exotic Garden of Monaco, and a founding member of the IOS (International Organization of Succulent Plants).

== Description ==
'''Vatricania''' is a monotypic genus of columnar cacti forming dense stands.

'''Habit''': Columnar, branching from the base; forming candelabra-like groups or “forests”.
'''Stems''': Erect, up to 5 m tall and около 10 cm in diameter.
'''Ribs''': Numerous (up to 27), weakly tuberculate.
'''Areoles''': Closely spaced, woolly.
'''Spines''': Relatively short, около 2–3 cm.
'''Cephalium''': Longitudinal, developing on mature stems; dense with spines and red wool, becoming grey with age.
'''Flowers''': Nocturnal, remaining open into the morning; broadly campanulate; white to yellowish or pale to intense pink; self-sterile.
'''Floral tube''': Covered with numerous bristles and pinkish wool.
'''Pollination''': Chiropterophilous (bats).
'''Fruits''': Scaly, deeply sunken within the cephalium.
'''Seeds''': Ovoid, dark brown, shiny, slightly tuberculate and striate; dispersal myrmecochorous (by ants).

== Habitat ==
Occurs in Andean intermontane environments:

rocky hillsides and valleys
shrubby vegetation zones
often forming dense cactus stands (“cactus forests”)

Altitude range: approximately 800–2000 m.

== Distribution ==
Bolivia:

Chuquisaca
Cochabamba
Santa Cruz

== Taxonomy ==
The genus has undergone significant re-evaluation.

Key points:

Described by Backeberg (1950)
Long treated as a synonym of ''Espostoa'' (e.g. Anderson 2001; Hunt et al. 2006)
Nyffeler & Eggli (2010): restored ''Vatricania'' as a distinct genus
Schlumpberger (2012): molecular data place it outside ''Espostoa'', within a clade related to ''Weberbauerocereus'' and ''Cleistocactus''
Anatomical studies (Mauseth 1999): revealed multiple unique traits, including a double-walled hypodermis

The genus is therefore considered evolutionarily distinct and not part of ''Espostoa'' sensu stricto.

== Species ==
Monotypic genus:

[[Vatricania guentheri]]

== Notes ==

Forms some of the most impressive cactus “forests” in Bolivia.
Despite morphological similarity to ''Espostoa'', molecular and anatomical data clearly separate the genus.
Shows affinity with the “Cleistocactus clade” rather than woolly columnar genera.

}}

== Etymology ==
The name means "Echinopsis with bristles", referring to the floral tube covered with characteristic hairs and bristles.

== Description ==
'''Setiechinopsis''' is a monotypic genus of small, short-lived cacti with a distinctive floral morphology.

* '''Habit''': Small, usually solitary; sometimes branching; lifespan typically 3–5 years.
* '''Roots''': Short, thick taproot with fine secondary roots.
* '''Stems''': Cylindrical, strongly pigmented; brownish or purplish-green to nearly black.
* '''Ribs''': 11–12, low and straight.
* '''Areoles''': Covered with white wool.
* '''Spines''': 9–14 radial spines; 1 longer central spine; fine and slightly pubescent.
* '''Flowers''': Nocturnal, funnel-shaped, white, strongly scented; appearing near the apex; self-fertile.
* '''Floral tube''': Very long, slender, scaly, covered with hairs and bristles.
* '''Pollination''': By long-tongued moths (e.g. ''Manduca sexta'').
* '''Fruits''': Fusiform, drying at maturity; longitudinally dehiscent; floral remains persistent.
* '''Seeds''': Globose to elongated, dark brown, dull, tuberculate, with mucilage.

== Habitat ==
Occurs in unusual habitats for cacti:

* saline and brackish soils
* grasslands and open shrublands (e.g. ''Atriplex'')
* foothills and low mountain areas

Altitude range: approximately 200–1250 m.

== Distribution ==
Argentina:

* Catamarca
* La Rioja
* Mendoza
* San Juan
* San Luis
* Santiago del Estero

== Taxonomy ==
The genus has a complex history but is now widely accepted.

Key points:

* Originally described as ''Echinopsis mirabilis'' (Spegazzini, 1905)
* Later transferred to multiple genera (''Arthrocereus'', ''Acanthopetalus'')
* Often included in ''Echinopsis'' sensu lato in modern classifications
* Ritz et al. (2007): showed it is not part of ''Echinopsis''
* Las Peñas et al. (2010): cytogenetic evidence supports separation
* Albesiano & Kiesling (2012): identified multiple autapomorphies
* Schlumpberger & Renner (2012): placed it basally in a clade with ''Denmoza'' and related taxa

The genus is therefore recognized as distinct and evolutionarily isolated.

== Species ==
Monotypic genus:

* [[Setiechinopsis mirabilis]]

== Notes ==
* One of the shortest-lived genera within Cactaceae.
* Morphology shows strong convergence with ''Echinopsis'', but molecular data contradicts this relationship.
* Adapted to atypical, often saline environments.
* Represents an early-diverging lineage within its clade.

* '''Seeds''': Variable, black, dull to slightly shiny; ovate to helmet-shaped, with prominent hilum.

== Habitat ==
High-altitude Andean environments:

* rocky soils, slopes and crevices
* highland grasslands and plateaus
* often partially buried (mimetic growth)
* frequently associated with mosses and lichens

Altitude range: approximately 1600–3600 m.

== Distribution ==
South America:

* Bolivia (Chuquisaca, Cochabamba, Potosí, Santa Cruz, Tarija)
* Argentina (Jujuy)

== Taxonomy ==
The genus is highly complex and has undergone major reinterpretation.

Key points:

* Strong morphological overlap between ''Weingartia'' and ''Sulcorebutia''
* Molecular studies show no clear separation between these groups
* ''Cintia'' is also embedded within the same lineage

Current interpretation:

* '''Weingartia sensu lato''' includes:
* ''Sulcorebutia''
* ''Cintia''

The taxa form a single, genetically cohesive group despite high morphological variability.

}}

== Etymology ==
Named in honour of Pierre Rebut (1828–1898), a French cactus nurseryman.

== Description ==
'''Rebutia''' is a genus of small, low-growing cacti, often forming dense clusters.

* '''Habit''': Globose, depressed or shortly cylindrical; solitary or clumping.
* '''Areoles''': Rounded, ovate or elliptic.
* '''Spines''': Very variable; usually fine, short, often hair-like; typically white.
* '''Flowers''': Diurnal, funnel-shaped, relatively large compared to the body; yellow, orange, pink or red; usually self-fertile.
* '''Pericarpel''': Nearly glabrous (diagnostic for ''Rebutia'' s.s.).
* '''Pollination''': Mainly by bees.
* '''Fruits''': Small, globose; dry and papery when ripe; disintegrating.
* '''Seeds''': Numerous, black, shiny, ovate.
* '''Dispersal''': Myrmecochorous (by ants).

== Habitat ==
Occurs in high-altitude environments:

* rock crevices and rocky slopes
* highland grasslands and open areas

Altitude range: approximately 1200–3600 m.

Adapted to cold conditions, including snow and frost, typically under low humidity.

== Distribution ==
South America:

* Argentina (Catamarca, Jujuy, Salta, Tucumán)
* Bolivia (Tarija)

== Taxonomy ==
The genus is taxonomically complex and historically controversial.

Key points:

* Traditionally expanded to include ''Aylostera'', ''Sulcorebutia'' and ''Weingartia''
* Ritz et al. (2007): demonstrated that ''Rebutia'' sensu lato is polyphyletic
* Mosti et al. (2011): confirmed separation into distinct clades
* Hernández-Hernández et al. (2011): supported deep divergence between these groups

Current interpretation:

* '''Rebutia sensu stricto''' is a distinct lineage
* ''Aylostera'' (incl. ''Mediolobivia'' and others) represents a separate clade
* ''Sulcorebutia'' and ''Weingartia'' form another independent lineage

The genus is therefore treated here in a '''narrow sense (s.s.)'''.

== Species ==
Following Joël Lodé (2015), with a restricted species concept:

* [[Rebutia fabrisii]]
* [[Rebutia krainziana]]
* [[Rebutia marsoneri]]
* [[Rebutia minuscula]]
** [[Rebutia minuscula subsp. wessneriana]]
* [[Rebutia padcayensis]]

== Notes ==
* One of the most popular genera in cultivation due to abundant flowering.
* Shows extreme variability, especially within ''R. minuscula''.
* Historically over-expanded, leading to major taxonomic confusion.
* Current trend is toward splitting into multiple genera based on molecular data.

}}

== Etymology ==
Named in honour of Werner Uebelmann (1921–2014), Swiss cactus collector and nurseryman known for his work in South America.

== Description ==
'''Uebelmannia''' is a genus of small, usually solitary cacti with distinctive epidermis and dense rib structure.

* '''Habit''': Globose to short columnar; usually solitary, rarely reaching up to 1.5 m in height.
* '''Epidermis''': Smooth, papillose or waxy; often dark and glossy.
* '''Ribs''': Numerous, sharply defined or tuberculate.
* '''Areoles''': Very closely spaced.
* '''Spines''': Fragile, easily detachable; sometimes pectinate (notably in ''U. pectinifera'').
* '''Flowers''': Diurnal, small (up to ~2.5 cm), funnel-shaped, yellow; apical or subapical; self-sterile.
* '''Pollination''': Likely by bees.
* '''Fruits''': Elongated, berry-like; red to yellowish-green; dry and dehiscent at maturity.
* '''Seeds''': Black, rough to warty, ovate to spoon-shaped.
* '''Dispersal''': Possibly myrmecochorous (by ants).

== Habitat ==
Endemic to mountainous regions of Brazil:

* quartz sands and acidic soils
* granite rock crevices
* highland slopes and plateaus

Altitude range: approximately 650–1460 m.

Often associated with ''Pilosocereus'', ''Cipocereus'', Velloziaceae, orchids and terrestrial bromeliads.
High atmospheric humidity with frequent mist; relatively cool temperatures for tropical regions.

== Distribution ==
Endemic to Brazil:

* Minas Gerais

== Taxonomy ==
The genus is well established but phylogenetically isolated.

Key points:

* Previously placed in Notocacteae based on morphology
* Nyffeler (1997, 1998): anatomical evidence excluded it from that tribe
* Nyffeler (2002): positioned ''Uebelmannia'' at the base of the "BCT" clade
* Hernández-Hernández et al. (2011): confirmed early divergence within this lineage
* Crozier (2005): referred to a distinct "Uebelmannia clade"

The genus is currently accepted and represents an early-diverging lineage within Cactoideae.

== Species ==
Currently three recognized species with subspecies:

* [[Uebelmannia buiningii]]
* [[Uebelmannia gummifera]]
** [[Uebelmannia gummifera subsp. meninensis]]
* [[Uebelmannia pectinifera]]
** [[Uebelmannia pectinifera subsp. eriocactoides]]
** [[Uebelmannia pectinifera subsp. flavispina]]
** [[Uebelmannia pectinifera subsp. horrida]]

== Notes ==
* One of the most morphologically distinctive cactus genera.
* Adapted to nutrient-poor, quartz-rich soils.
* Likely represents an ancient lineage within the BCT clade.
* Taxonomic limits at subspecies level remain under discussion.

}}

== Etymology ==
Named in honour of Francis Lynde Stetson (1846–1920), an American lawyer and botanically inclined patron associated with the New York Botanical Garden.

== Description ==
'''Stetsonia''' is a monotypic genus of massive, tree-like cacti.

* '''Habit''': Arborescent, strongly branched (often 100+ branches), forming a well-defined trunk up to ~40 cm in diameter; reaching up to 8 m tall.
* '''Stems''': Bluish-green, club-shaped, not segmented.
* '''Ribs''': 8–9, thick, slightly crenate.
* '''Areoles''': Woolly.
* '''Spines''': 7–9 radial spines up to ~3 cm; 1 central spine up to 7 cm or more, straight and sharp.
* '''Flowers''': Nocturnal, funnel-shaped, white and fragrant; remain open into daytime; self-sterile.
* '''Pollination''': Mainly by hawkmoths (Sphingidae).
* '''Fruits''': Globose to ovoid, green tinged with red, edible, scaly; perianth remnants deciduous.
* '''Seeds''': Small, brown to black, shiny, rough and warty; ovate to spoon-shaped.
* '''Dispersal''': Likely by mammals such as tapirs (''Tapirus terrestris'') and other fauna.

== Habitat ==
Occurs in dry lowland to montane environments:

* arid plains and dry forests
* Chaco vegetation and shrubby pampas
* hills and mountain slopes

Altitude range: typically 100–900 m, rarely up to ~2200 m.

Often associated with ''Cereus forbesii'' and ''Opuntia quimilo''.

== Distribution ==
South America:

* Argentina
* Bolivia
* Brazil (southern regions)
* Paraguay

== Taxonomy ==
The genus is currently accepted but has undergone shifting placement.

Key points:

* Initially placed in tribe Cereeae
* Barthlott & Hunt (1993): transferred to Browningieae
* Nyffeler (2002): positioned within the broader "BCT" clade
* Crozier (2005): supported placement in Cereeae
* Hernández-Hernández et al. (2011): confirmed inclusion in Cereeae

Current consensus places ''Stetsonia'' within Cereeae, likely in a basal position among South American lineages.

== Species ==
Monotypic genus:

* [[Stetsonia coryne]]

== Notes ==
* One of the largest tree-like cacti in South America.
* Represents an early-diverging lineage within Cereeae.
* Historically associated with Browningieae, a tribe now largely reinterpreted.
* Fruits are edible and play a role in local ecosystems.
