The myrtle rust fungus Uredo rangelii was first identified in South America and Jamaica on Myrtus communis (common myrtle) and Syzgium jambos (rose apple).
All members of the Myrtaceae plant family are potential hosts of myrtle rust.

Myrtle rust spores on mountain ash (Eucalyptus regnans) inoculated under controlled conditions. |
Across New South Wales and Queensland, myrtle rust has been found on over 150 Myrtaceae species. Infected properties include commercial plant nurseries, public amenities and large areas of bushland.
The Myrtaceae includes:
- gum trees (Eucalyptus)
- bottlebrush (Callistemon, Melaleuca)
- tea tree (Leptospermum)
- lilly pilly (Syzygium, Acmena, Waterhousea)
- paperbark (Melaleuca)
- myrtle (Backhousia)
- guava (Psidium)
- midgen berry/midyim (Austromyrtus)
- scrub cherry, rose apple (Syzygium)
- brush box (Lophostemon)
- christmas bush (Metrosideros)
- lophomyrtus (Lophomyrtus)
- willow myrtle (agonis)
Below is a list of genera in the Myrtaceae plant family.
