350 PROCEEDINGS OF SECTION D. 
THE COMMON EUCALYPTUS FLORA OF 
TASMANIA AND NEW SOUTH WALES. 
By J. H.Marpen, Government Botanist and Director, 
Botanic Gardens, Sydney. 
INTRODUCTORY. 
In my ‘Second Contribution towards a Flora of Mount 
Kosciusko” (Agric. Gaz. V.S.W., October, 1899), I have 
adduced evidence (supplementing that of Mueller), of a 
striking character, showing the remarkable similarity of 
the vegetation of that mountain to that of Tasmania. If 
the matter be further enquired into, it will be found that 
this similarity by no means alone refers to the mountain 
in question, but extends to many others parts of New 
South Wales. In both States Eucalyptus trees are the 
prevailing and most characteristic vegetation over enormous 
areas, and I think it will be a profitable field for enquiry 
to compare the species of this genus in Tasmania and New 
South Wales. To this end I have carefully examined the 
types; some of them, of course, originating in Tasmania, 
and some of them in New South Wales. It is a matter of 
great importance to trace a species over as extended an 
area as possible, for there is some danger of looking upon 
a species only from the points of view of its occurrence in 
a particular State. The Eucalypts know no political 
divisions between States, although those divisions are 
convenient for records as to range. The study of types in 
such a large and widely distributed genus as Eucalyptus 
is of such importance that it should be frequently insisted 
upon, in order that we may not make our comparisons , 
or deductions with false standards. 
I would point out that there is still much room for field- 
work in regard to the Tasmanian Eucalypts, and I 
trust that local botanists and collectors will support Mr. 
- Rodway in the efforts he.is making to throw light upon 
the many forms which Tasmania possesses. The other 
States have to face similar problems. 
A complete series of specimens of a Eucalypt includes, 
besides the ordinary mature foliage and buds, flowers and 
ripe fruits, young suckers (these are very important), 
and the more these young leaves differ from the mature 
ones, the more important it is to gather them. Then, 
again, we require characteristic specimens of the bark, and
