The Myrtacece are plants from warm countries. There are some 

 in ]S"ew Zealand, in Chili, and in the Mediterranean region, but the 

 greater part belong to tropical regions. In the south of Europe we 

 find only one Myrtle and the Pomegranate, and the latter has 

 doubtless been introduced, as have also several species from temperate 

 America and Australia, which are cultivated in the open air in the 

 Mediterranean region. All the Ghamcelauciece are Australian, and 

 also the greater part of the genera belonging to the Leptospermece. 

 Among the latter are several genera belonging to other parts of 

 Oceania, and especially to the Indian Archipelago : such are Mela' 

 leucay Tristania, Leptospermum^ BcecJcea^ Metrosideros ; the last is 

 found in India, at the Cape, and in Chili. The Eucalipts are almost 

 all Australian ; but the genus is also represented in a very restricted 

 manner in the Indian Archipelago. Acicalyptus, Philiocalyx, and 

 Spermolefis have as yet been observed only in the Yiti isles and in 

 New Caledonia. There is only one American Leptosperm, Teijualia 

 {Metrosideros). The distribution of Myrtese is much more varied 

 and extended ; thus there are Myrtles in all parts of the world, and 



^ More rarely dispermous. * Endl. Gen. 745 (1839). — H. Bn. Tayer Fam.
