== Etymology ==
The genus is named in honor of Maximilian Joseph Eugène Auguste Napoléon de Beauharnais, 3rd Duke of Leuchtenberg (1817–1852), a French-Russian nobleman and supporter of the sciences.

== Description ==
'''Leuchtenbergia''' is a unique monotypic genus characterized by its extreme morphological convergence with the genus ''Agave''.
* '''Stems''': Solitary or slowly offsetting from the base, reaching up to 50 cm in height. It has a thick, woody underground caudex.
* '''Tubercles''': Unlike almost all other cacti, it lacks ribs. Instead, it has very long (up to 12 cm), slender, three-angled tubercles that resemble agave leaves.
* '''Spines''': Located at the tips of the tubercles. They are papery, flexible, and straw-colored, often reaching 10-15 cm in length, mimicking dry grass for camouflage.
* '''Flowers''': Large (up to 10 cm wide), diurnal, and fragrant. They appear from the center of the new tubercles at the apex. The color is a brilliant, silky yellow.
* '''Fruits''': Smooth, oblong, and greenish-purple. When ripe, they dry and open by a basal pore.
* '''Seeds''': Large, black, and pitted.

== Habitat ==
The genus grows in the Chihuahuan Desert, often hidden among limestone rocks and dry grasses. Its papery spines and long tubercles provide excellent camouflage against herbivores. Altitudinal range: 600–2000 m.

== Distribution ==
* '''Mexico''': Widespread but sparse in the north-central states (Coahuila, Guanajuato, Hidalgo, Nuevo León, San Luis Potosí, Tamaulipas, Zacatecas).

== Species ==
Following the classification of Lodé (2015), the genus remains monotypic:

* [[Leuchtenbergia principis]] (Type species)

== Taxonomy ==
Despite its unusual appearance, molecular studies (Vázquez-Sánchez et al., 2013) place ''Leuchtenbergia'' firmly within the '''Ferocactus''' clade. Lodé maintains it as a separate genus due to its extreme morphological specialization, which is unique within the tribe '''Cacteae'''.
