water with others flourishing on fresh water creeks, one might be 

 led to separate them ; and yet there is nothing in these varieties to 

 nnrk specific characters. Notazlea ligustrina, or one of our native 

 olives, is another of Brown's plants. The allied species N. ovata 

 is much more common in this colony, and I believe it was from 

 that species that Mr. Shepherd succeeded in obtaining some good 

 specimens of olive oil. Persoonia Caleyi does not occur in the 

 neighbourhood of Sydney, but it closely resembles some of the 

 species so familiar to us under the name of geebung. Taxanthema 

 Australis is now transferred to the genus Statice. It is mentioned 

 as one of the plants found in the early days of the colony at Port 

 Jackson and Hunter's Eiver, but I do not think it can be common, 

 as I have never succeeded in finding it in a wild state 



Having noticed the lithograms which illustrate the plants de- 

 scribed by Brown, I now turn to those remaining figures which 

 also represent species common to New South Wales and Victoria. 

 Of these (exclusive of MirleUa oxylobioides, which is said to have 

 been found in Argyle by Cunningham), there are twenty-eight 

 lithograms of plants which occur in various parts of the colony, some 

 near the coast, and others in the interior. The family which Dr. 

 Mueller has laboured most effectually to describe is that of the 

 Composites, which, whether regarded as one of the most extensive 

 in this part of the world, or whether contemplated as exercising 

 more profoundly than any other, the skill of the scientific botanist, 

 is attended with much difficulty. In other orders, flowers which 

 closely resemble each other may frequently be referred to their 

 respective genera with moderate care and attention ; but amongst 

 Composites it sometimes happens that plants which are widely 

 separated by technical distinctions, appear very similar in their 

 general characters, the classification depending mainly on the 

 shape of the style. Amongst these Composites, there are eight 

 species figured which may be said to belong to this colony, viz. : 

 Solenogyne bellioides ; Senecio vagus; Myriogyne Cunninghami ; 

 Eclipta platyglossa ; Elacliothamnus Cunningliami \ Humea ozo- 

 thamnoides ; Polycalymma Stuartii ; and Ethuliopsis dioica. The 

 first of these Composites is a little plant of the daisy kind, which, 

 perhaps, is one of the commonest we have ; but unless considered 

 microscopically with reference to the adaptation of its organs for 

 the functions designed by nature, it has but little beauty to re-
