Definition
The *genus Lophophora* comprises small, spineless cacti native to Mexico and the southwestern United States, most notably the peyote cactus (*Lophophora williamsii*). Think of *Lophophora* as the zen masters of the cactus world, small, unassuming, yet holding deep cultural significance. These cacti are characterized by their soft, blue-green bodies and lack of spines, featuring tufts of woolly hairs instead. They are slow-growing and contain psychoactive alkaloids, traditionally used in religious and spiritual ceremonies. Conservation efforts are crucial due to habitat loss and over-collection.
