species, discovered formerly in the great Gulf of Carpen- 
taria, there were several most interesting new plants. With 
a view towards an entire completion of the survey of the 
several coasts of the continent, that part of New South 
Wales within the tropic, north of Gape Bedford, which was 
not seen by Captain Cook, entered into the plans of the 
Mermaid’s second voyage, and it was highly gratifying to 
my feelings to reflect, that it was reserved for me to com- 
plete several specimens, discovered formerly in imperfect 
states by those eminent naturalists who accompanied the 
above great circumnavigator, in 1770, desiderata, that have 
been wanting ever since this period of their discovery ; no 
mediums of communication with those particular parts of 
the coast having presented themselves. 
The aggregate of the several collections that have been 
formed during the progress of the four voyages, under the 
general circumstances above briefly referred to, and which, 
as constituting a small Herbarium, will be thus collectively 
spoken of in the following remarks, does not exceed one 
thousand three hundred species of Phoenogamous plants ; 
of these five hundred and twenty are already described by 
authors, the other portion being in part unpublished species, 
previously discovered on other coasts of Terra Australis, 
and in part absolutely new, referrible, however, mostly to 
well defined genera. Of Cryptogamous plants, there are 
but few species, and of these, or parasitical Orchidese, none 
have been detected in these voyages in addition to those 
already described : a circumstance, that with respect to the 
North-west Coast can reasonably be accounted for, from the 
non-existence of primary mountains, or land above very mo- 
derate elevation; by the absence of lofty dense forests, 
(points of character necessary to that permanency of atmo- 
spheric moisture, which constitutes an essential requisite to
