Lophophora

Lophophora is a genus of slow-growing, spineless cacti native to regions of northern Mexico and the southwestern United States. The most well-known species in this genus is *Lophophora williamsii*, commonly known as peyote. The genus is characterized by its small, globe-shaped appearance, bluish-green to grayish-green color, and ribbed or tubercled surface. These cacti typically grow low to the ground, often resembling small, fleshy buttons.

The flowers of Lophophora are small, white to pinkish, and grow from the center of the plant. This genus is notable for producing psychoactive alkaloids, most prominently mescaline, a substance traditionally used by indigenous cultures for spiritual and medicinal purposes. *Lophophora* species thrive in arid desert conditions, and their growth is quite slow, making them highly adapted to their harsh environments. The genus is of great cultural and historical significance, especially in connection with the Native American Church and traditional ceremonies involving peyote.
