between Ilibbertia ^xi(\. PapaveracecB,^ and between Tdraccriv and the 

 tribe Cimoniece of the Saxifrarjacets. 



Tbe geographical distribution of the BUleniaceoi is little compli- 

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

 AustraUan origin/ as are nearly all the llibhcriias, about eighty in 

 number •* two species alone, belonging to the section Hemistemma, 

 have been observed in Madagascar.' IJUlenia,^ ScJmmacheria,^ Acro- 

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

 species of Wormia alone grow in the eastern islands of Africa,'" and 

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

 Japan, and the north of Tndia.'^ Davilla,^^ Empedodea,^' 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) sannentosa is found 

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

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

 like II. roluhilis, have thefa'tid smell of Poppies. 

 If we suppose their carpels opened out, and put 

 edge to edge, we have the flower of Pajpaver at 

 once." 



2 We need only recall the fact that Telra- 

 carpaa has been classed among the Dilleniacece 

 (see p. 113), and that Itea and Stachyurus re- 

 call forcibly Clethra, Scmrauja, and Actinidia.
