This genus is indiginous to regions of Bolivia and Argentina. These cacti make a hardy and easy to grow specimen for the beginning collector. Requires strong sunlight to thrive. The name of the Genus is derived from the Greek "kleistos" for closed.

At least one species from this Genus has been reported to contain unspecified alkaloids.


This genus is comprised of 70 known species which are generally characterized as a small, globular, somewhat flattened spiny cactus. The tubercles are usually arranged in 13 rows tipped with small radial spines. Several species of this Genus contain alkaloids which are chemically similar to epinephrine.
