252 MR. 8. MOORE ON THE FLORA 
Composite. 
Half the desert species are distributed through Australia, but 
of these rather less than l are not found in the South-west 
corner. Only + are South-western species which penetrate into 
the desert but do not range beyond it. 
Solanacee. 
The desert species of Solanum outnumber those in the South- 
west, and only 1 of these occur also in the South-west, while 3 
are known from the Eastern Colonies. 
Myoporinee. 
3 of the species are restricted to the desert, a remarkably high 
proportion ; while if we include species confined to the deserts 
of South and West Australia, 1 the Myoporineous flora is 
endemic. Only + of the desert species occur in the South-west, 
while nearly 1 are known from the Eastern Colonies. 
Epacridee. 
The dwindling of this order in the desert is very remarkable, 
it being represented there only by between 2 and 3 per cent. of 
species advancing from the South-west. 
Loranthacee. 
Noteworthy as being better represented in the desert than in 
the South-west. 3 the desert species are found in the Eastern 
Colonies, and 3 in the South-west. 
Casuarinee. 
There are more than $ as many desert as South-western 
species; 2 are South-western, and as many are found in one or 
more of the Eastern Colonies, but not in the South-west corner. 
Orchidee. 
Only 8 per cent. of South-western species occur in the desert. 
Restiacee. 
This order falls off greatly in the desert, the percentage of 
desert to South-western species being between 4 and 5 only. 
Graminee. 
This order is noticeable for the small number of South-western 
species which advance into the desert and do not penetrate east 
of it, less than 75 of the grass-flora consisting of such species,
