Eucalyptus being naturally such a well-defined genus, it has very few generic 

 synonyms. Those that are accounted synonyms are not synonyms of the whole 

 genus, and comprise two only, viz. : — 



(a) Eudesmia, R.Br., which was the name given to one species {tetragona) 



looked upon by Brown as connecting Eucalyptus with Angophora . 



(b) Symphyomyrtus, Schauer., which consists of a form of E. comula, Labill., 



with the walls of the fruits fused together. 



Aromadendrum, Anderson (Dr. TV. Anderson, the surgeon of Cook's second and 

 third voyages), is a nomen nudum. A second Aromadendrwm (Blume) is 

 a genus of Magnoliacea\ 



The vast majority of species are Australian. The known exceptions are two 

 species extending to Timor, and two or three or perhaps one single somewhat doubtful 

 species from the Indian Archipelago ; one from New Britain. Species have been 

 described by Naudin from cultivated specimens in the south of France and by 

 Kinney from California, but, in my opinion, they are referable to Australian species. 



The botanical literature of Eucalyptus is very scattered. Most of the 

 original descriptions of Robert Brown remain in manuscript, while later work has 

 rendered some of them of only historical value. I do not hesitate to say that the 

 suppression of these descriptions has been a heavy blow to British botanical science, 

 whether this suppression eventually met with the acquiescence of Robert Brown 

 himself or whether he was controlled, in this respect, by superior authority. 



The first published attempt to get the increasing number of species of 

 Eucalyptus into order was by Augustin Pyramus de Candolle iu his Prodromus, vol. 

 iii, 216 et seq. (1828). The Eucalyptus portion of Don's " General History of 

 Dichlamydeous Plants," vol. ii, 818 et seq. (1832), is mainly a translation of the 

 preceding. 



Then follows the important work of TV. P. TValpers, "Repertorium botanices 

 systematicae." (Leipzig.) Vols, ii and v contain an important series of 

 descriptions of species. This work was continued as " Annales botanices System- 

 aticae," and vols, i and ii also contain descriptions of Eucalyptus.
