list of most of these, excluding about 15, which are water-plants, 

 or species whose range is limited. The letter " I." placed before 

 a species signifies that it is Icelandic, and I have introduced 

 it to show how many are absent from this island also, but how 

 many are present. The letter " S." indicates that the species is 

 found in the South Temperate or Antarctic Circle. The asterisk 

 (*) indicates that the species is Arctic both in East America and 

 Europe.
