General/Distribution:

A moderate-sized genus of c. 250 species, of which 215 are endemic to Australia and the rest in Indo-Malaya. Represented in our flora by 2 cultivated species.

Comment/Acknowledgements:

In Melaleuca the stamens are longer than petals and this character is used to separate it from many genera. It is similar to Callistemon and Kunzea but differs in having the stamens united in bundles opposite the petals.
