== 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.
