of a circular dish-shaped depression, which is filled with nectar smelling like sour cream. Kemer 

 says that the position of the stiff somewhat inwardly curved gynophore, to the tip of which pollen 

 adheres, does not seem to be an adaptation to insects; but a kangaroo, which equals in height 

 the average bushes of Dryandra, would when licking the nectar and introducing its snout into 

 the cup-shaped inflorescence, undoubtedly remove pollen from the stamens that surround the 

 cup, and might transfer it to another inflorescence. But until direct observations are forthcoming 

 ' kangaroo flowers' cannot be included in our classification. 



[The symbols here given, which will be used throughout this translation, correspond to .words 

 employed in English books, and therefore deviate in many cases from Miiller 's symbols. Tr.] 



* Certain flowers included here are devoid of nectar, especially some Papilionaceae (Ulex, 

 Sarothamnus, Genista), but they cannot, as explained above, be separated on that account from llie 

 other flowers of class H. Other flowers placed here are False A^ectar flowers, and their sugary juices 

 must first be bored for (e.g. Orchis) ; or they may offer to visitors the contents of little knobs filled 

 with sweet sap.
