Callistemon /ˌkælɪˈstiːmən/[2] is a genus of shrubs in the family Myrtaceae, first described as a genus in 1814.[3] The entire genus is endemic to Australia but widely cultivated in many other regions and naturalised in scattered locations.[4] Their status as a separate taxon is in doubt, some authorities accepting that the difference between callistemons and melaleucas is not sufficient for them to be grouped in a separate genus.
