APPENDIX. {Botany of Terra Australis. 
enjoyed no common advantages, through the liberality of Sir Joseph Banks, 
in whose Herbarium I had not only access to nearly the whole of the spe- 
cies of plants previously brought from Terra Australis, but received speci- 
mens of all those of which there were duplicates. Of these plants, exceeding 
1000 species, the far greater part were collected by Sir Joseph Banks 
himself, in the vogage in which New South Wales was discovered. Ihe 
rest were found at Adventure Bay in Van Diemen’s Land, by Mr. David 
Nelson, in the third voyage of captain Cook; at King Georges’s Sound on 
the south-west coast of New Holland, by Mr. Menzies, in captain Van- 
couver’s voyage ; and in the colony of New South Wales by several bota- 
nists, especially the late colonel Paterson and Mr. David Burton. Since 
my return from New Holland 1 have had opportunities of examining, in 
the same Herbarium, many new species, found in New South Wales by 
Mr. George Caley, an acute and indefatigable botanist, who resided nearly 
ten years in that colony : and have received from the late colonel Paterson 
several species discovered by himself within the limits ol the colony of Port 
Dalrymple ; which was established under his command, 
I have also examined, in the Sherardian Herbarium at Oxford, the 
greater part of the plants brought from Shark’s Bay by the celebrated 
navigator Dam pier, and have seen a few additional species from that and 
other parts of the West Coast of New Holland, collected in the voyage of 
captain Baudin. 
The additional species obtained from all these collections are Op- 
wards of 300 ; my materials, therefore, for the commencement of a Id ora 
of Terra Australis amount to about 4200 species ; a small number certainly 
for a country nearly equal in size to the whole of Europe, but not incon- 
siderable for the detached portions of its shores hitherto examined. 
In Persoon’s Synopsis, the latest general work on pbuenogamous 
plants, their number is nearly 21000. The cryptogamous plants already 
published, by various authors, exceed 6000 ; and if to these be added the 
phsenogamous plants that have appeared in different works since the pub- 
lication of Persoon’s Synopsis, and the unpublished species of »oth classes 
already existing in the collections of Europe, the number of plants at pre- 
sent known may be estimated at 33000, even exclusive of those peculiar to 
Terra Australis. 
The observations in the present essay being chiefly on extensive
