166 FLOSA OF JEIiSFiy. 



A list such as this is necessarily to some extent dependent upon 

 the judgment of the individual who compDes it. Questions will 

 arise, for instance, as to whether a plant is a -colonist or only a 

 frequent casual. In the Jersey list Setaria viridis and Panicum 

 Crus-galli are included, but not Lepidium Draba and Amarantus 

 retroflexus. Another botanist might include, or exclude, all four. 

 Again, it is difficult to know how to deal with such plants as 

 Smyrnium Olusatrum and CEgopodium Podagraria, which are 

 certainly relics of cultivation as a rule, but ma,y well have been 

 native once within the area. In such cases I have taken the 

 Continental distribution as the best guide. No plant has been 

 included, or excluded, without a deliberate consideration of its 

 claims. Plants which were undoubtedly native once but have 

 become extinct are included, as they form part of the indigenous 

 vegetation. 



The first column is devoted to Jersey, the second to Guernsey 

 (including the smaller islands of Herm and Jethou), the thu-d to 

 Aldernej', the fourth to Sark (including Brechou). The last 

 column indicates the European distribution. Where nothing is 

 said the plant in question is found all over Europe, exclusive of 

 the Arctic Circle. Plants marked " Arctic " penetrate within the 

 Circle. The other notes explain themselves. 



Considering the size of the area, the list is a long one, especially 

 if the scant courtesy which segregate species and ambiguous 

 records have received is taken into account.
