Calocephalus was then left yet without any appellation for its species. 

 Kuntze therefore makes Leucophyta supersede Calocephalus, and con- 

 sequently the 10 species of the latter genus appear in his work (p. 351! 

 under ^Leucophyta. His transfer, as may be seen from the seeond edition 

 of the writer's „Census of Australian Plants" (p. 140) affects 11 species; 

 but in the „Key to the System of Victorian Planta" the desirability of 

 uniting 0. citreus and C. lacteus has already been indicated four years 

 ago, limiting the species to 10. The differences between the two plants 

 just inentioned do not seem to be specific, as even the delineations by 

 Decaisne in the botanic Atlas to the „Voyage de la Coquille" show only 

 diversities indicative of varieties, so that the colour of the flower-cluster* 

 seeins to remain the only distinctive characteristic. But in the „Fragni. 

 Phytogr. Austral. " III. 136 (1863) it was already remarked, that many 

 of our Everlasting with yellow involucres are varying with white invo- 

 lucral bracts. Therefore th^ Calocephalus Lessingi, of the „Key", 

 combining C. lacteus and C. citreus, should now be called Leucophyta 

 Lessingi, after the restoration of that genus.
