_ We have dwelt on this paper at greater length than usual, for in 
it are far more than ‘‘ veteris vestigia flammz.” We extract an in- 
teresting passage supplemental to some observations of Dr. Brown’s 
published in 1814 in the Botanical Ppgoniix to Captain Flinders’s 
Voyage. 
**From the knowledge I then had of New Holland, or Australian 
vegetation, I stated that its chief peculiarities existed in the greatest 
degree in a parallel included between 33° and 35° S. lat., which I 
therefore called the principal parallel, but that these peculiarities or 
_ characteristic tribes were found chiefly at its western and eastern 
extremities, being remarkably diminished in that intermediate por- 
tion included between 133° and 138° E. long. These observations 
related entirely to the shores of Australia, its interior being at that 
period altogether unknown; and the species of Australian plants 
with which I was then acquainted did not exceed 4200. Since that 
time great additions have been made to the number, chiefly by Mr. 
Allan Cunningham, in his various journeys from Port Jackson, and 
on the shores of the north and north-west coasts during the voyages 
of Captain King, whom he accompanied ; by Messrs. William Baxter, 
James Drummond, and M. Preiss, at.the western extremity of the 
principal parallel; and by Mr. Ronald Gunn, in Van Diemen’s Land. 
It is probable that I may be considered as underrating these addi- 
tions, when I venture to state them as only between two and three 
thousand, and that the whole number of Australian plants at pre- 
sent known does not exceed, but rather falls short of, 7000 species. 
«*'These additions, whatever their amount may be, confirm my ori- 
ginal statement respecting the distribution of the characteristic tribes 
of the New Holland flora; some additional breadth might perhaps 
be given to the principal parallel, and the extent of the peculiar fa- 
milies may now be stated as much greater at or near its western 
than at its eastern extremity. 
“With the vegetation of the extra-tropical interior of'Australia, we 
are now in some degree acquainted, chiefly from the collections formed 
by the late Mr. Allan Cunningham, and Charles Fraser, in Oxley’ s 
_ two expeditions from Port Jackson into the western interior, in 1817 
and 1818; from Captain Sturt’s early expeditions, in which the 
rivers Darling, Murrumbidgee, and Murray, were discovered ; from 
those of Sir Thomas Mitchell, who never failed to form extensive 
collections of plants of the regions he visited ; and lastly, from Cap- 
tain Sturt’s present collection. 
‘“The whole number of plants collected in these various expedi- 
tions may be estimated at about 700 or 750 species ; and the gene-
