Syzygium microphyllum is a species of plant in the Myrtaceae family. It is endemic to India. It is threatened by habitat loss. In 1998 the now disputed taxon Syzygium gambleanum was listed as extinct in the IUCN Red List. However after research work by the Royal Botanic Gardens Kew this plant was revealed as identical with Syzygium microphyllum and so the name Syzygium gambleanum became an illegitimate synonym.
