Aztekium ritteri

Aztekium ritteri, known in Mexico as peyotillo, is a species of cactus. It originated in Mexico, and is sometimes used as an ornamental plant.

Though the plant contains n-methyltyramanie, hordenine, anhalidine, mescaline, pellotine, and 3-methoxytyramine, there are no ethnobotanical reports of it being used by native aborigines.

Description
The species is considered as a shrub. The flowers are white or pink in color, measuring less than 1 cm in diameter. Its flowers bloom throughout the summer. After the flowers mature, they grow into a pink fruit, which opens when ripe, and releases several tiny seeds.

Naming
Friedrich H. Bödecker named the species in honor of German botanist, Friedrich Ritter.
