Synonym(s): Lophophora williamsii var. echinata
USDA Symbol: LOWI
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.
