Lophophora williamsii aka Indian Dope

Lophophora williamsii, commonly known as peyote, is a small, spineless cactus native to Mexico and southwestern Texas. Its clustered green, yellow, or red shoots can grow up to 7 cm (2.76 in) tall, and its flowers open during the day with a pink, white, red, or yellowish color. Behind the flowers are pink, elongated fruits that become brownish-white when mature, with black, pear-shaped seeds inside. Peyote has at least 5,500 years of entheogenic and medicinal use by indigenous North Americans and is believed to contain psychoactive alkaloids, particularly mescaline. The word peyote comes from the Nahuatl word meaning “caterpillar cocoon” and the plant was first formally described in 1845 by French botanist Charles Antoine Lemaire and assigned to the genus Lophophora in 1894 by American botanist John Merle Coulter. Despite its long history of use, peyote is illegal in most of the western world and grows in gravelly clay and loam soils on gentle slopes.
