L6 ON THE CAMPANTTLACEOUS AND OLEACEOU3 ORDERS.

The presence 



or absence, the freedom or union, and the varied activation of the 

 parts of the corolla afford generic, but no tribual characters. 



G-eographical distribution does not coincide with tribual differ- 

 ences. Jasminum, Nyctanthes, Schrebera, Olea, and Myxopyrum 

 belong to the tropical or subtropical regions of the Old World.

 Ligustrum are from the northern extratropical districts of the 

 Old World, the first three almost limited to the Mediterranean 

 region ; Ligustrum is also European, but is more abundant in 

 East Asia, whence it has even stretched across the tropics to Aus- 

 tralia. Osmanthus and OMomnthus are common to eastern Asia 

 and North America. Fraxinus extends all rm^rl ««» ^^o™

 character. It belongs to a series of genera which at the present 

 period are represented at once in South Africa, in extratropical

America. 



There remain two small genera, both of them slight modifica- 

 of the tropical Linocier a— one, Notelcea, represented in the Canary 

 Islands and in Australia, the other, Noronhea, limited to the Mas- 

 carene Islands. 



The Salvadoraceae, like some of their Oleaceous allies, appear to 

 have had their origin in the East tropical African or Africano- 

 Indian region, having extended northwards as far as Persia, 

 southwards to the Cape, and eastwards, though sparingly, to the 

 Malayan archipelago.
