Australia is not only rich in species, but that in its Flora generally 

 there is " a singular uniformity, purely Australian without 

 admixture of any other element." 



Of the Myrtaceous order not found in Western Australia, but 

 occurring in greater or less abundance along the Eastern and 

 Northern Costs, the following genera may be enumerated : — 



Baccate. 

 Rhodomyrtus. 

 Myrtus. 

 Rhodamnia. 

 Fenzlia 

 Decaspermum. 

 Eugenia. 

 Acicalyptus. 

 Barriagtonia. 



13. Carey a. 



14. Sonneratia. 



1. Tristania (including Lophostemon) has eight species in 

 Australia, of which four belong to N. S. Wales. Besides these, 

 there are two in N. Caledonia, and four in the Indian Archipelago, 



2. Metrosideros (with which Baron Mueller unites Syncarpia) is 

 dispersed over the Islands of the Pacific and Indian Archipelago 

 from New Zealand to the Sandwich Islands. 



3. Backhousea is a genus confined to Australia, and so far as 

 known, does not extend beyond Queensland and N. S. Wales. 



4. Osbornia, a genus constituted by F. von Mueller is represented 

 by one species in N. Australia and the Islands adjacent. 



5. Rhodomyrtus has four species in Eastern Australia, and there 

 is another widely distributed over the Indian Archipelago and 

 extending to China. 



6. Myrtus is common to the New and Old World, and the 

 Australian species are limited to Queensland and N. S. Wales. 



7. Rhodamnia is spread over Tropical Asia, and four species are 

 divided between Queensland and N. S. Wales. 



8. Fenzlia is purely a genus of E. and N. Australia.
