Cannabis (/ˈkænəbɪs/)[2] is a genus of flowering plants in the family Cannabaceae. The number of species within the genus is disputed. Three species may be recognized: Cannabis sativa, Cannabis indica, and Cannabis ruderalis; C. ruderalis may be included within C. sativa; all three may be treated as subspecies of a single species, C. sativa;[1][3][4][5] or C. sativa may be accepted as a single undivided species.[6] The genus is widely accepted as being indigenous to and originating from Central Asia, with some researchers also including upper South Asiain its origin.[7][8] Kingdom: Plantae Clade: Angiosperms Clade: Eudicots Clade: Rosids Order: Rosales Family: Cannabaceae Genus: Cannabis
