Description

This cactus generally has a single cylindrical stem a few cm wide and up to about 25 cm (9.8 in) tall and 3 to 8 cm (1.2 to 3.1 in) in diameter with tuberous roots. The cylindrical warts do not produce milky juice, and the axillae are covered with bristles. Each cluster of spines is made up of 3 or 4 dark, hooked central spines and many straight, white radial spines, the longest reaching 2.5 cm (0.98 in) in length. The 30 to 60 radial spines are hair-like, arranged in two rows, white with dark tips, and 6 to 10 mm (0.24 to 0.39 in) long. The flower is 2 to 4 cm (0.79 to 1.57 in) wide and pink to lavender in color. The fruit is red, shiny, 1.2 cm (0.47 in) long and fleshy and contains many black seeds coated in corky arils. [2]

Distribution

Cochemiea tetrancistra is found in California, Arizona, Nevada, Utah, and the Mexican states of Baja California and Sonora at elevations of 100 to 1500 meters. [3]

Taxonomy

Originally described as Mammillaria tetrancistra by George Engelmann in 1852, the name tetrancistra comes from Greek words for 'four' and 'hook,' referring to the hooked central spines. [4] In 2021, Peter B. Breslin and Lucas C. Majure reclassified it into the genus Cochemiea. [5]

Cochemiea fraileana is a species of Cochemiea found in Mexico This species is native to Mexico and can be found along the east coast of the southern part of Baja California Peninsula in Desert Scrub communities. They tend to grow in non-calcareous dry granite-based soil but can also grow in rocky habitats, either in rock fissures or directly on top of the rock surface even without the presence of soil. Thus, the mineral composition of the rocks in their habitat directly influences their abundance. The habitat of Cochemiea fraileana is home to succulent flora and is particularly rich in local endemics. Currently, no major threats to the species are known to exist.
