BOTANY OF TERRA AUSTRALIS. 65 



Africa and are comparatively rare in Tei-ra Australis are in 

 South America entirely wanting ; and I am acquainted 

 with no tribe of plants common to South Africa and South 

 America and at the same time wanting in Terra Austrahs, 

 unless the Compositse with bilabiate corolla. 



I'he character of the New Zealand Flora, known to us 

 chiefly from the materials collected by Sir Joseph Banks, is to 

 a considerable degree peculiar ; it has still, however, a certain 

 affinity to those of the two great countries between which 

 it is situated, and approaching rather to that of Terra Aus- 

 tralis, than of South America. 



In comparing together the Floras of Terra Australis and 

 Europe, I shall chiefly confine myself to an enumeration of 

 the species common to both countries ; the subject at pre- 

 sent hardly admitting of many remarks of a more general 

 nature. It may, however, be observed, that none of the 

 great natural orders of Europe are absolutely wanting in 

 Terra Australis ; that some of them, as Compositse, Legu- 

 minosae, Graminese and Cyperacese, are found even in 

 nearly the same proportion ; while others, as Cruciferae, 

 Ranunculacese, Caryophyllese, Rosacese, and Ericese are 

 reduced to very few species ; and that several of the less 

 extensive European orders, namely, Saxifragese, Cistinese, 

 Berberides, Kesedacese, Fumariacese, Grossularinae, Vale- 

 rianese, Dipsaceas, Polemonidese, Globularise, Elseagnese, 

 and Equisetacese in Terra Austrahs do not at all exist. 



The greater number of Australian genera, except the [69o 

 Acotyledonous, differ from those of Europe ; there are, 

 however, a few European genera, as Utricularia, Drosera, 

 and Samolus, that appear to have even their maxinium in 

 Terra Australis. 



From the following list of species, common to Terra 

 Australis and Europe, I have carefully excluded all such as, 

 though now existing in the different settlements, have evi- 

 dently, or probably, been introduced, and I am satisfied 

 that no naturahsed plant will be found in it except, perhaps, 

 Cynodon Dactylon. 



I have also excluded certain plants, as Elatine Hydro- 

 piper, Geuni urbanum, OxaJis cornicukda, Lycopus euro-
