EXPLANATORY NOTES. 
It will lie seen by reference to Bent ham’s “ Flora Aus- 
traliensis,” Mueller’s “ Census of Australian Plants,” and 
Mueller’s “ Key to the Plants of Victoria,” that name 
changes in many of our Victorian species have been made. 
Botanists specializing in certain groups of plants have 
published the results of their careful revision of the same, 
based on the study of material in the principal herbaria in 
the world. Many of these monographs have been edited 
by Engler in his great work, “ Das Pflanzenreich,” and 
their diagnoses have been accepted generally by leading 
botanists, including Mr. J. H. Maiden, whose “Census of 
the Plants of New South Wales” has been of considerable 
assistance to the compilers of this List. 
As an instance of this. Prof. Carl Mez, in Engle/’s work, 
discusses the generic distinctions between Myrsine and 
Rapanea Myrsinaceae), and shows that no true Myrsine 
occurs in Australia, so that our Mutton-wood tree, so long 
known as Myrsine variabilis, appears as Rapanea variabilis. 
Other changes of a like nature made by recent investigators 
may be mentioned— e.g,, the separation of Eriostcmon, 
Phebalium, and a few smaller groups, as given in Bentliam’s 
Flora, instead of lumping all under Eriostemon ; and the 
keeping apart of Leucopogon, Melichrus, Lissanthe, &c., 
instead of placing them under Styphelia, as Mueller arranged 
them. 
Other changes are due to early mistakes in determination 
— e.g.; Gleiclienia Hermannii was recorded from specimens 
which proved to be G. lesvigaia. Specimens labelled Aizoon 
zygophylloides were later found to be the introduced 
Mesernbvianthemuhi angulatnm , and a form of Acacia longi- 
folia was recorded as A. glancescens. 
Many changes, also, in specific names were made in 
accordance with rules agreed to at the Vienna Conference 
of Botanists held in 1905. It was there decided that the 
specific name first given to any plant described since 
Linnaean publication should stand as the only valid one— 
e.g., Buy.Ionia sub-alpina, F. v. M., being the former name 
for the plant we have long known as Pultencea rosea,
