## Distribution

Polaskia chichipe is found in a small area of mountains of northern Oaxaca, Michoacán, and southern Puebla, Mexico. It grows in xerophytic shrubland between 1,600 and 2,300 meters above sea level.[1] It is found growing along Cephalocereus mezcalaensis, Polaskia chende, Mammillaria haageana subsp. haageana, Ferocactus robustus, Agave karwinskii, Agave lechuguilla and Yucca periculosa.[4]

## Taxonomy

The species was first described as Cereus chichipe by Robert Roland-Gosselin in 1905. The specific name "chichipe" comes from a common name in Spanish. In 1949, Curt Backeberg reclassified the species into the genus Polaskia.[5]
