Genus Ocimum is an aromatic herbaceous plant used in perfumery, flavouring and pharmaceutical products. A detailed study on inter-relationship, phylogeny and evolutionary aspects in various Ocimum species, their different morphotypes and geographical races was carried out based on morphology, distribution, cytogenetical parameters, hybridization, essential oils, breeding, and key diagnostic characters.
