Lophophora williamsii (Peyote)
Trout, Keeper

Lophophora williamsii

Lophophora williamsii (Lem. ex Salm-Dyck) J.M. Coult.


Cactaceae (Cactus Family)

Synonym(s): Lophophora williamsii var. echinata


USDA Native Status: L48 (N)

Low, gray, spineless, nearly hemispherical stems growing singly or in broad dense clumps, topped by several pink flowers.

Cut and dried "buttons" of Peyote, when chewed, produce color hallucinations and are important in certain Native American religious ceremonies. The plant contains narcotics. A federal permit is required to possess any part of the plant. In Texas Peyote has been almost eliminated by collectors, but in areas of Mexico it is still very common.
