NATURAL HISTORY OF PLANTS. 39 



The Austrian Flora stretches from the circle of Austria over Mo 

 tavia, the southern part of Poland, Hungary, Moldavia, Wallachia, 

 Bulgaria, Servia, Bosnia, Croatia, Sclavonic, Istria, and Dahnatia. 



The Pyrenean Flora occupies all Spain, the islands of Majorca and 

 Minorca ; perhaps also Portugal, but here our information fails. 



The Apennine Flora extends over the whole of Italy, Sardinia, 

 Corsica, and a part of Sicily. 



If we make a Catalogue of the plants of these five different Floras, 

 the local distribution of them will be very remarkable. 



It is also easy to imagine that various mixtures of the different 

 Floras must have taken place after the firm land was formed and 

 settled. This is the reason why the south of France, where the 

 Helvetian and Pyrenean Floras mingle, is so rich in plants. In 

 Piedmont the Pyrenean, the Helvetian, and the Apennine- Floras 

 meet; and thither also, by means of the sea, are the plants of the 

 north of Africa brought. For the same reason, Great Britain con. 

 sists partly of the northern, and partly of the Helvetian Flora; and 

 in Cornwall, the most southern point of the kingdom, the plants 

 of the Pyrenean Flora, by means of the oblique position of the 

 Spanish coast, are mixed with the others. Sweden, Denmark, and 

 Russia, have not maintained the northern Flora pure ; many plants 

 of the Helvetian have found their way thither. The same may be 

 said of Germany, and particularly of the mark of Brandenburg, 

 where, besides the Helvetic Flora, we have received a part of the 

 northern. From the northern we have certainly acquired the Ma- 

 laxis Loselis, Neottia i epens, Helonias borealis, Vaccinium Oxtj. 

 coccos, Ledompulustre, Andromeda polifoli a, Linnaea borealis, 

 and many others. From the Helvetic Flora the following, Chi- 

 .ronia Centanrca, Euphorbia Cyparissias, Cucubalus Otites % and 

 the most of our plants. 



It is very remarkable, that two such common plants as the Eu- 

 phorbia Cyparissias and Cucubalus Otites, should disappear about 

 twenty German miles from Berlin towards the north, and are not 

 again to be met with, though they prosper perfectly well in the 

 northern botanic gardens. Perhaps these plants will in time sow 

 themselves further north, and proceed, by degrees, in the same 

 direction. Who will say that they have not advanced in a greater 

 degree during the last century, that many plants have not also ex f
