Lophophora (/ləˈfɒfərə/)^{[citation needed]} is a genus of spineless, button-like cacti. Its area range covers southern through northeastern and north-central Mexico to Querétaro in central Mexico.^{[citation needed]} The species are extremely slow growing, sometimes taking up to thirty years to reach flowering age (at the size of about a golf ball, excluding the root) in the wild.^{[citation needed]} Cultivated specimens grow considerably faster, usually taking between three and ten years to reach from seedling to mature flowering adult.^{[citation needed]} The slow rate of reproduction and over-harvesting by collectors render the species under threat in the wild.^{[citation needed]}
