DILLENIACEJE.

between HibbeHia and Papaveracea,^ and between Tetracerd- and the 

 tribe Cunoniea of the Saxifragaceai. 



The geographical distribution of the Dilleniacea is little compli- 

 cated. The score of species belonging to our Candollca series are of 

 Australian origin/ as are nearly all the Hibbertias, about eighty in 

 number ■* two species alone, belonging to the section Hemidemma^ 

 have been observed in Madagascar/ BiUenia^ Schumacher ia^ Acro- 

 trema^ and nearly all the Wormias^ are natives of tropical Asia ; two 

 species of Worniia alone grow in the eastern islands of Africa/" and 

 only one in Australia." Actinidia has only been observed in China, 

 Japan, and the north of India.'" Bavilla^^ Empedoclea^^ and CurafeUa}' 

 are three exclusively American genera. Tetracera, also very abundant 

 in tropical America,"^ is the genus most widely spread over the globe ; 

 it is found in Senegal and Guinea,'' Madagascar and the east coast of 

 Africa,'^ tropical and eastern Asia,'^ the Indian Archipelago,'" New 

 Caledonia,"' and Australia." Tetracera {Delima) sarvientosa is found 

 over a large extent of tropical and eastern Asia."^ The number of 



' " It is very singular," we have observed 

 {Adansonia, vi. 275), " that certain Hibbertias, 

 like R. voluMlis, have the foutid smell of Poppies. 

 If we suppose their carpels opened out, and put 

 edge to edge, we have the flower of Fapaver at 

 once." 



2 We need only recall the fact that Tetra- 

 carpeea has been classed among the Dilleniacece 

 (see p. 113), and that Ilea and Stachyunis re- 

 call forcibly Clethra, Saurauja, and Actinidia.
