This recently described species (in Agaves del Occidente de Mexico, 2007) superficially resembles A. pelona of the northern state of Sonora in its smooth leaf-margins and extended apical spine. However, A. chazaroi comes from the other end of the country in Jalisco, where it inhabits cliffs in tropical deciduous forest between 900 and 1200 m. It also differs in its more slender, spreading leaves and its yellowish-green rather than red flowers.
