Description

Turbinicarpus valdezianus, one of the smallest and slowest-growing plants in its genus, has tiny feathery spines that obscure its body. While it is usually found growing solitary, it can occasionally form clumps. When young, this plant has spherical stems that later become cylindrical with a narrower base and short, spirally arranged tubercles. The apex is entirely covered by the plumose spination. About half of the plant is underground, supported by a substantial taproot. These plants typically reach heights of 3-5 cm and diameters of 1-2 cm. They are adorned with 25-30 dense, feathery, white spines, each measuring around 0.5 mm long and spreading flat around the areoles.^[4]

In the spring, Turbinicarpus valdezianus produces 1-5 flowers that open during the day at the plant's apex. It is found scattered in small populations across various locations. The color of its flowers varies from pinkish-white to bright pink, with darker magenta or reddish-brown midveins.^[4]

Distribution

This species thrives in the Chihuahuan Desert of Mexico, ranging from Saltillo in Coahuila state to nearly Matehuala in San Luis Potosí, at elevations of 1400 to 1600 meters. Its natural habitat is hot deserts. It is threatened by habitat loss.
