The green, slightly curved shoots are less than 1 meter long and have a diameter of up to 7 centimeters.There are 9 to 12 sharp-edged ribs, 1 to 2 cm high, that are slightly curved and wavy on the back and that are up to 2 centimeters high. The areoles are 3 to 5 mm long, 1 to 1.5 centimeters apart. The spines are gray with a darker tip. The single central spine is up to 1.5 centimeters, the 6 to 8 radial spines 0.3 to 1.5 centimeters long.

Distribution

[edit]

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

[edit]

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]
