NicotianaThe tobacco plant belongs to the family of Solanacea (same as potatoes and tomatoes), and to the genus of Nicotiana. Tobaccos grown for smoking products are classified in the subgenus Nicotiana Tabacum, species Nicotiana Tabacum L. But after decades of gene tampering and uncontrolled hybridations, it is impossible to know exactly what is what! After much research conducted during the 20th century, it seems that all grown tobaccos are coming from 4 original subspecies : Havanensis, Brasi.
