There are no natural orders restricted to Australia except 

 Tremandiece* which though confined to this continent has much 

 affinity with Pittoxporece (through Cheir anther a), as well as 

 PolygaJece. But there are certain natural orders called Australian, 

 not because they are restricted to Australia, but because they 

 are best represented there, and rare elsewhere They are 

 Stackhousice, containing only about 20 species, and of which 

 representatives are found in N. Zealand, and the Philippine 

 Islands; Goodeniaeece, very closely allied to CampanuJaeeos and 

 Zobeliacece ; Stylidiece, the same ; Epaeridece, an order almost 

 confined to Australia ; those species found outside belonging to 

 four of the 24 Australia genera, except one S. American species, 

 and one or two from N. Caledonia, which might almost be 

 referred to the Australians ; and Casnamice, an order which has 

 only a single genus. There are very few species which are not 

 Australian. There are also two sections of Juncacece, which were 

 regarded as orders by Hooker, Xerotece and Aphyllanthece. There 

 are other orders not strictly Australian, but which are largely 

 developed on the Continent, and are more or less characteristic 

 of its vegetation. These are Dilleniacece, Rutacece, Proteaeece, 

 Restiacece, Tlnjmelece, Droseraeece. Two other orders were included 

 by Hooker, but they are only regarded as sections of Amaryllidece, 

 and Sterculiaeece. With the exception of Dilleniacece, which 

 after Australia abounds most in India, all the other orders are 

 abundant in South Africa next to Australia. 



We must remember however that these Australian features are 

 developed more in the South-west part of the Continent than 

 elsewhere, and that the Tropics contain them in the smallest 

 proportion. Of the very Australian genera, only one (Epaeridece) 



* Bninoniacece was also included by Hooker, but this as depending upon one 

 species has been included as a very aberrant form of Goodeniaeece.
