Syzygium bharathii, a new species from Megamalai Wildlife Sanctuary, Tamil Nadu, India is described. This species is closely allied to Syzygium benthamianum and Syzygium agastyamalayanum but differs from both by having a cylindrical stem with red young shootlets, glabrous leaves with wavy margin, quadrangular peduncle, large sized flower, inwardly curved filaments, narrow pyriform hypanthium, obovate, subglobose, ellipsoid fruits and ovate-obovate seeds. This combination of characters makes determining the relationships of S.bharathii difficult.
