Abstract

The genus Ocimum means fragrant-lipped, characterized by the presence of the upper lobe of the calyx, which is large and
decurrent. Ocimum gratissimum L. is conventionally known as Clove Basil due to its foliage which smells like cloves. The present study
reports the extant distribution of O. gratissimum L. ssp. gratissimum var. macrophyllum Briq. across northeastern India. It is a new
distribution record for the flora of Assam and northeastern India. A comprehensive description along with photographs, taxonomic notes, and diagnostic keys has been provided to aid identification.
