What is coryphanta?

Coryphantha is a genus of cacti that is native to the southwestern United States, Mexico, and parts of Central America. There are over 60 species of Coryphantha, which vary in size and appearance. Some are small and globular, while others are larger and columnar. The plants typically have clusters of spines that can vary in color from light tan to dark brown. Some species also produce small, colorful flowers that bloom in spring or summer. Coryphantha cacti are popular among collectors and growers due to their unique appearance and hardiness. They are also important ecologically as a source of food and shelter for desert animals and insects. However, some species are threatened by habitat loss, collecting, and other forms of human activity.
