Maguey Oteroi (Agave oteroi)

Agave oteroi García-Mend. & E. Solano

A small-rosette agave of the Puebla orbit, named in honor of the Mexican botanist Manuel Otero and one of several candidate species behind the unstable local name cachetón. Research coverage in primary literature is thin, and this page is deliberately short.

AgaveA genus is one level above a species in biological classification. The genus Agave contains roughly 200 species of rosette-forming succulents native to the Americas; it includes every plant used to make tequila, mezcal, raicilla, bacanora, comiteco, and most other Mexican agave spirits.IUCN: Not evaluatedThe IUCN (International Union for Conservation of Nature) Red List rates the extinction risk of every species it has assessed. “Not evaluated” means the species hasn't been assessed by IUCN against Red List criteria.🦇 Bat-pollinatedIn nature, this species is pollinated by long-nosed bats (Leptonycteris and Choeronycteris) that visit its flowers at night to feed on nectar. In commercial fields the plants are usually harvested before they flower, which severs the relationship.

At a glance

Agave oteroi García-Mend. & E. Solano is a small-rosette agave of the Puebla orbit, named in honor of the Mexican botanist Manuel Otero by Abisaí J. García-Mendoza (UNAM) and Estela Solano. The taxon is a relatively recent addition to the formal taxonomy of the genus, well after the colonial-era naming of better-known species like Agave potatorum. It is one of several candidate species behind the unstable local name cachetón, the regional Puebla and Guerrero label whose underlying botany is not settled across sources.

This entry is deliberately short. Primary literature coverage of A. oteroi is thin in the secondary press and absent from the consolidated agave-spirits research corpus this page is built on. Where the better-documented Puebla agaves carry hundreds of pages of peer-reviewed ecology behind them, A. oteroi does not, at least not yet, in any source this site has been able to verify directly.

The descriptive material below is at the floor of editorial confidence. Almost every claim on this page should be read as provisional pending direct verification against the original García-Mendoza and Solano publication and any subsequent peer-reviewed work on the species. The page exists to record the connection from the cachetón local name to a botanical candidate, not to assert ecological or morphological detail.

Naming and authorship

The species epithet oteroi honors Manuel Otero, a Mexican botanist whose contribution to the documentation of Mexican flora is the reason García-Mendoza and Solano chose the name. Dedicating an epithet to a botanist or naturalist is common across Agave, particularly for taxa described in the late twentieth and early twenty-first centuries when much of the remaining formal-description work in the genus was carried out by Mexican-led teams. García-Mendoza in particular has been the most prolific contemporary describer of new agave species, including a large fraction of the Puebla-Oaxaca taxa this site catalogues.

The site has not been able to independently confirm the original publication year of A. oteroi beyond the broad statement that the species is a recent description. A reader needing the original citation should consult García-Mendoza's institutional publication record at UNAM's Jardín Botánico.

Range and the cachetón connection

The species is recorded from Puebla in central-southern Mexico, in the same general highlands and canyon country that supports A. potatorum and several other small-rosette agaves of the region. More precise habitat and elevation data are not in the secondary literature this entry has been able to consult.

A. oteroi enters this site primarily through the back door: it is one of several candidate species that producers and importers have, in some market-facing listings, named as the botanical referent for cachetón. The cachetón mapping is genuinely unstable. Some sources tie cachetón to the jabalí family and to A. convallis; some tie it to A. oteroi; a third reading sees it as a regional folk name for forms of A. potatorum. This site does not commit to any single mapping.

Low confidenceLow confidence: information here is partial, based on limited sources, or has not yet been cross-checked. Read with caution and treat specific facts as provisional.

The "Puebla" range attribution comes from market-facing producer listings and from the secondary mention in the cachetón local-name research, not from a published distribution map for A. oteroi. Range extension into neighboring states is plausible by analogy to neighboring species but unverified.

Mezcal use, conservation, and what is not yet known

Mezcal attributed to A. oteroi in market listings is a small-batch, wild-harvested product from Puebla. The sensory descriptors reviewed for the cachetón entry (resinous, herbal, prone to vigorous fermentation) likely describe whatever plant is in the still on a given run rather than describing A. oteroi specifically. Until a bottling carries a verified, species-level certificate of analysis identifying the raw material as oteroi, the sensory profile of the species in isolation is not something this site can characterize honestly.

No formal IUCN Red List assessment for A. oteroi has been located, and the species is recorded here as not evaluated. Propagation biology, flowering timing, and pollinator confirmation are likewise not in the secondary record. This site assumes bat pollination by genus-level analogy, the default across Agave, but the assertion is not based on direct observation of A. oteroi flowers. The botany chapter discusses the bat-agave pollination relationship at length, and the genus-level pattern almost certainly applies; the species-level evidence for oteroi is a layer of confidence below what this site asserts for better-documented agaves.
