 jegliche positive Unterlageu. Dasselbe gilt, wenn man die einzelnen Unter-

 darstellen ? BUNGE meiut, weun man von den unvollkonmieusteu zu den voll- 

 kommeneu fortsclu'eite, habe man sie so anzuordueu : Salicorniefe, Corispsrmeae, 

 Cheuopodiaae, Camphorosmese, Atripliceae, Suaadeas, Sodeae, Anabaseae. Was

 data, yet when we take mutation, crossing and other possibilities into con- 

 sideration as causes of species variation, we are quite convinced that it is 

 altogether impossible to establish the affiliation between species and species 

 by studying their constitutional characters. 



78 Amarantacese : Closely related to the Chenopodiacepe, and Phyto- 

 laccacese. The family is also allied to the PortulacaceEe, Aizoace?e and Caryo- 

 phyllacese.

79 Ny ctaginaceae ^ : Close relation exists between the Phytolaccacesa 

 and the Nyctagiuacere ; wln'le by Cryptocarpus, Bemchenbachia and Colignonia 

 of the latter family, they are connected with the Chenopodiaceae. 



80 Cynocrambacese 3>) : This family bears some relations to the Urti- 

 caceae, Chenopodiacese, Phytolaccace?e, Begoniacece, Santalaceae, Monimiacess 

 and Caryophj-llacefe according to different views. 



81 Phytolaccacese 4) : Very near the Aizoacese, Nyctaginacese and to 

 the Chenopodiaceae. 



82 AizoaceaB 5) : Near the Portulacacete and Caryophyllacepe. The family 

 is also allied to the Phytolaccaceae in its typical apetalous flower. At any
