Mueller has given, in his ' General Report on the Botany of the North Australian Expedition,' 
some valuable tables, showing approximately the order of succession in which temperate forms appear 
in advancing southward in Australia, and these give us a wide idea of the immensely extended dis- 
tribution of many endemic species. He enumerates no less than 225 Victoria colony species as 
occurring to the north of lat. 26° S., and of these I find nearly 90 to be Tasmanian. Many of them 
are properly tropical forms that attain the latitude of Victoria only in the hot deserts, bnt many arc 
essentially temperate forms. The whole are thus distributed : — 
Lat. 17 30' S. to 20° £

The diminution of vegetable forms in advancing from temperate to tropical Australia is to I 
great extent due to the rarity or absence of Orders which, though more typical of hot latitudes in 
other parts of the globe, abound in the temperate regions only of Australia. I have marked these 
with an asterisk in the following list of cxtratropical xVustralian Orders that diminish rapidly or are 
absent in the tropics of that continent : —

Those Orders, again, which are confined to the Tropics, are unexccptionally common Indian ones, 
and which it is not necessary to specify. There are, however, several of the most typically Indian 
Orders that are very scarce or absent in tropical Australia, amongst which the most remarkable are :— 
Ehamneae. 
Melastomaceae. 
Araliaceae. 
Vaccinieae. 
Acanthaceae. 
Cyrtandreae. 
Laurineae. 
Cupuliferae. 
Dioscorese.
