Agave inaequidens K.Koch
Unequal-toothed Agave
Agave inaequidens, commonly known as maguey de monte, is one of the most important agaves in traditional mezcal production in western Mexico. It is distributed across the montane slopes of the Trans-Mexican Volcanic Belt and the Sierra Madre del Sur, between 1,500 and 2,500 m a.s.l. It forms large, open rosettes with leaves bearing irregularly spaced marginal teeth — the characteristic from which its scientific name derives. Its piña is prized by mezcal masters of Michoacán and Jalisco. The species comprises several recognized subspecies, including the striking ssp. barrancensis from the ravines of Jalisco.

Overview
| Category | Classification |
|---|---|
| Family | Asparagaceae |
| Genus | Agave |
| Growth Habit | Large, open, acaulescent or short-stemmed rosette, monocarpic. Diameter 1–2.5 m at maturity. Produces basal offsets with moderate frequency. |
| Conservation Status | Least Concern (LC) – IUCN. Extraction for artisanal mezcal may exert local pressure on wild populations. |
| pH Target | 6.0–7.5 |
| Type | Sandy-loam to slatey, well-drained |
Origin & Habitat
Morphology
Lanceolate to linear-lanceolate, 80–150 cm long and 8–14 cm wide, dull green to glaucous green. Margin with irregular corneous teeth (hence 'inaequidens': unequal teeth), grey to brown, and a terminal spine 3–6 cm long.
ecoYellowish-green, 7–10 cm long, arranged in dense panicles on a floral scape 6–10 m tall. Flowering occurs only once at the end of the plant's life.
ecoAcaulescent or with a very short stem. The central piña, rich in inulin and fermentable sugars, can weigh between 30 and 80 kg in mature specimens ready for mezcal production.
ecoShallow and widely spreading root system. Main roots do not penetrate deeper than 50–80 cm but spread radially several metres to maximise water uptake.

"One of the primary sources of artisanal mezcal in Michoacán; local mezcal masters call it simply 'maguey de monte'. Ssp. barrancensis is notably different in appearance and may warrant species rank based on recent molecular studies."
