498 Transactions.—Miscellaneous. 
tions. of all the countries concerned, by the occurrence of so many New 
Zealand genera and species in Eastern Australia, and the absence from New 
Zealand of so many characteristic Australian orders and genera. It would 
be out of place here to go into these points minutely, because to do so would 
involve a mere recapitulation of Mr. Wallace’s able and conclusive argu- 
ments, and I shall therefore confine myself only to a short examination of 
the relations of our flora to that of Eastern and Western Australia respec- 
tively. I have to apologize if I now descend into statistics, as the subject 
can hardly be treated in any other manner. 
New Zealand possesses altogether 310 genera of flowering plants (303 
A.R.W.), of which 248 (251 A.R.W.) are found in Australia, and of this 
number 146 range into Western Australia. But of these, no less than 114 
genera are more or less widely distributed outside the Australasian region, 
leaving only 81 genera, peculiar to New Zealand and Australia, which range 
into Western Australia. I append the names of these genera below,* but my 
knowledge of the Australian flora is much too limited to enable me to say 
how many of them have their head-quarters in Eastern or how many in 
Western Australia. In this connection greater interest attaches to those 
species which occur in both New Zealand and Western Australia. There are 
altogether 215 New Zealand species (belonging to 134 genera) found in 
Australia, many of them being antarctic or South American forms which 
occur very sparingly on the mountains of Victoria and Tasmania. Of these

that we aa still 88 spcainal of limited dispersion to consider. Of these 24t 
belong to genera whose head-quarters are outside of Australia, and theif 
spread into Western Australia is probably more recent than into New Zea- a 4
