Systematics and distribution
Agave ocahui grows in the state of Sonora in Mexico on volcanic slopes, in grasslands and open woodlands at an altitude of 500 to 1400 m.
The first description by Gentry was published in 1972.
Agave ocahui is a member of the Amolae group and grows widely scattered in the northeast of the state of Sonora . It can hardly be distinguished from agave pelona in its habitus in its youth stage , but the differences in leaf and flower structure of adult specimens become clear. Due to the leaf and flower structure, Agave ocahui is related to Agave vilmoriniana and Agave chrysoglossa . Individuals can be found in the University of California Botanical Gardens.
Agave ocahui can withstand short periods of frost down to −8 ° C when it is dry.
