Cultigen

From Wikipedia, the free encyclopedia

Cultigen is the name given to organisms, particularly cultivated plants such as Salvia divinorum, that do not have a wild or uncultivated counterpart for one of two reasons. Either its wild bretheren are now extinct, or its species was domesticated (grown and selected by humankind) from so far back in antiquity, and has undergone such drastic transformation under prehistoric human selection, that the plant's ancestry is essentially unknown.
