Ariocarpus fissuratus (formerly known as Anhalonium fissuratus) is a species of cactus found in small numbers in northern Mexico and Texas in the United States. Common names include living rock cactus, false peyote, chautle,[1] dry whiskey and star cactus.[2]


This cactus consists of many small tubercles growing from a large tap root. They are usually solitary, rarely giving rise to side shoots from old areoles. The plant is greyish-green in color, sometimes taking on a yellowish tint with age. Its growth rate is extremely slow. A. fissuratus is naturally camouflaged in its habitat, making it difficult to spot.[2] When they are found, it is usually due to their pinkish flowers which bloom in October and early November.[2]


In cultivation, Ariocarpus fissuratus is often grafted to a faster-growing columnar cactus to speed growth, as they would generally take at least a decade to reach maturity on their own. They require very little water and fertilizer, a good amount of light, and a loose sandy soil with good drainage.


Ariocarpus fissuratus is a unique species in that it has been used by Native American tribes as a mind-altering substance, usually only as a substitute for peyote.[3] While it does not contain mescaline like many other North American cactus species (such as peyote), it has been found to contain other centrally active substances, such as N-methyltyramine and hordenine,[3] albeit in doses too small to be active.
