(Abstract: A taxonomic study on the diversity of the genus Knema Lour. belonging to the family Myristicaceae R. Br. in India revealed the distribution of the ten taxa under four series in North East and Peninsular India and Andaman and Nicobar Islands including two endemic species. Knema ser. Obovoideae W.J. de Wilde is synonymised here under ser. Knema. Series Knema is represented by two species and ser. Glaucae W.J. de Wilde by one species in North East India, while ser. Laurinae W.J. de Wilde is represented by three species and two subspecies in North East India and Andaman and Nicobar Island, and ser. Glomeratae W.J. de Wilde by 2 species in South and NE India. This is the first taxonomic study on the genus in India. All the taxa are cited with updated nomenclature, diagnostic characters, distribution, phonological data, vernacular names, line drawings, photo plates and specimens examined in various herbaria. Taxonomic keys are provided for easy identification of these taxa).
