G4G OX THE MYRTACE.E OF AUSTRALIA, 



9. Decaspermum (Nelitris of Fl. Aust.) has in Queensland one 

 species only and that is common to the Indian Archipelago and the 

 Philippine Islands. 



10. Eugenia has 20 species in E. Australia, four of which occur 

 in the East Indies and the Archipelago, E, jambolana in particular 

 being very common there and yielding a fruit much eaten. 



11. Acicalyptus is the " Scaly-bark Tree " of Lord Howe's Island 

 (Frag. Vol. 8, p. 15). 



12. Barririyfonia is a genus confined to the Tropics of the Old 

 World but having two species in Queensland and one iu N. 

 Australia. 



13. Careya has three East Indian species, one of which in 

 Queensland and N. Australia is supposed to be identical with 6'. 

 arborea. 



14. Sonneratia (placed amongst Lythrarieae in the Fl. Aust.) 

 has one species common to the Indian Archipelago and W. 

 Australia. 



It appears, therefore, that whilst 16 Myrtaceous Genera are 

 peculiar to Western Australia and do not extend beyond it (except 

 in two or three cases), there are 14 Genera in N. and E. Australia, 

 which are common to other regions, and not found near what is 

 termed •' the centrum of Australian Vegetation." Mr. Bentham, 

 in the concluding preface to the 7th Vol., of the Flora AustraKensis, 

 confirms the views of Hooker in the Essay already quoted, and is of 

 opinion, that, although the predominant portion of the Australian 

 Flora is strictly indigenous ; yet that a number of genera whose 

 main station is in Tropical Asia extend more or less into Tropical 

 and Eastern Australia, thereby giving to the vegetation of E. 

 Queensland an Asiatic character. In alluding to that part of 

 Australia where some of the Myrtaceous genera, as seen in the 

 foregoing list, are strictly endemic, the same illustrious author 

 speaks of "the remarkable isolation and highly differentiated 

 character of the Flora in the south-west corner." Amongst the 

 genera so isolated, are Darioinia and Verticordia, the one with 37 

 and the other with 38 species. These with several other genera are 

 not represented in the south-east extremity of the continent, whilst
