Of the above, Saxifraga oppositifolia is probably the most 

 ubiquitous, and may be considered the commonest and most 

 arctic flowering plant. 



The following are also inhabitants of all the five arctic areas, 

 but do not usually attain such high latitudes as the foregoing : —

The absence of Gentiana and Primula in these lists is very 

 unaccountable, seeing how abundant and very alpine they are on 

 the Alps and Himalaya, and Gentiana on the South American 

 Cordilleras also. 



The few remaining plants, which are all very northern and 

 almost or wholly confined to the arctic zone, are the following.
