Austria. Of its distinctness from Persicaria, there seems much more 

 reason to doubt, although my series of specimens are not yet suffi- 

 cient to connect the two presumed species.

On the prevalence of European Genera and Species of Plants in the 

 hilly parts of the province of South Australia. By Thomas 

 CoRDER, Esq., A.L.S. 



The settled part of the above province is pretty much confined to 

 the district between the Gulf of St. Vincent and the river Murray, 

 and is divided into two parts by a range of hills of considerable ele- 

 vation. Running north and south between these hills and the sea, the 

 country is principally a level plain, lightly timbered with various 

 species of Eucalyptus, Callitris, Banksia, Casuarina, Exocarpus and 

 Acacia, which list comprises nearly all the trees in the colony. The 

 vegetation is of a very exotic character, but in the vicinity of Adelaide 

 I have noticed Poa annua and Polygonum aviculare in great profusion 

 by the sides of foot-paths and roads. 



The country beyond the hills is table-land, elevated about 1200 feet, 

 and sloping gradually towards the Murray and lake Alexandrina. It 

 is diversified with forest ranges and open grassy valleys, and watered 

 by numerous small streams, which, however, cease to flow in the dry 

 season. The vegetation in this district bears great affinity to that of 

 Europe, with the exception of the trees, which are pretty much the 

 same as described above. The most common grass is the kangaroo 

 grass ( Anthisteria australis), but Poa trivialis and annua, Festuca, 

 Bromus, Avena, Briza, Agrostis and several others are frequently met 

 with. The brooks and streams abound with the common reed 

 (Arundo Phragmitis), Typha angustifolia, Glyceria fluitans, Lycopus 

 europseus ; and the swampy ground produces the marsh mallow 

 {Althaa officinalis). The only Australian llubus [R. australis) grows 

 in similar situations ; the fruit resembles the raspberry, but is very 

 rarely produced. The pastures are covered in spring with a Ranun- 

 culus closely resembling R. bulbosus, but with tuberous roots, and 

 two species of Viola. I have also gathered Matricaria Chamomilla, 

 Melilotus officinalis, Centaurea solstitialis, Lotus corniculatus (in very
