beaucoup de descripteurs a coiisiderercomme especes legitimes des 

 formes qui, pour d'autres, sont de simples varietes." 



At the same time the following passage (p. 410) shows that he 

 was inclined to split up species which Australian botanists with 

 ampler material do not : — 



" L' E. Lehmanni est certainement une des especes les plus 

 distinctes de tout le genre, et il serait difficile de le confondre 

 avec aucun autre." He then goes into the question of the 

 fusion of calyces which caused Schauer to form his genus Sym- 

 phyomijrtus. 



While it is evident from the notes I will give under each 

 species that I am of opinion that most of M. Naudin's species 

 cannot stand, yet I must point out that these Naudinian and 

 other species-names must -be respected in nomenclature, e.g., E. 

 amplifolia (unless superseded by a name of Robert Brown's) is a 

 name that must be adopted if Naudin's contention that this 

 particular form of E. tereiicorids is worthy of specific rank is 

 held to be valid. 



Naudin had not completed his work of naming, for he ends his 

 2nd Memoir with the words, " Plusieurs autres especes d'Euca- 

 lyptus existent dans nos jardins de Provence, mais leur etude 

 n'est pas assez avancee pour me permettre d'en parler dans ce 

 Memoire," 



It would add much to the value and interest of this paper if 

 it could be illustrated, but as this is impossible, I will elsewhere 

 publish figures of all species described from cultivated forms, 

 later on. It will then be more fully understood that a study of 

 cultivated forms is absolutely necessary for a proper realisation 

 of the affinities of the species. Affinities between species are 

 brought out by study of a long series of cultivated forms that 

 might not be suspected if spontaneous specimens were alone 

 examined. 



It must be borne in mind that the naming of Eucalypts from 

 cultivated specimens is not an invention of the moderns; the old 

 botanists freely indulged in it, and their nomenclature, often an
