THE CANADIAN NATURALIST. 



[June 



America ; and its absence in the whole southern temperate zone of 

 the Old World, except the Alps of Java. 



Thalictrum, Delphinium, Impxtiens, Primus, Circoea, Chrysos- 

 plenium, Parnassia, Bupleurum, Heracleum, Viburnum, Valeri- 

 ana, Artemisia, Vaccinium, Rhododendron, Pedicularis, and 

 Salix, are all arctic genera found on the tropical mountains of 

 Asia (Nilghiri, Ceylon, Java, etc.), but not yet in the south 

 temperate zones of Asia, and very few of them in Temperate 

 South Africa. 



There are, however, a considerable number of Scandinavian 

 plants which are not found in the Alps of Middle Europe, though 

 found in the Caucasus, Himalaya, etc. ; and conversely there are 

 several Arctic Asiatic and American plants found in the Alps of 

 Central Europe, but nowhere in Arctic Europe. In other words, 

 certain species extend from Arctic America through Central Asia 

 and North India to Central Europe, which do not extend from 

 Arctic America westward to Arctic Europe; and there are certain 

 other species which extend from Arctic Europe to the Caucasus 

 and Central Asia, which do neither exist on the Alps of Central 

 Europe nor extend eastward to Arctic America : thus, 



Common to Arctic Europe and Temperate Asia, etc., but not to 

 Alps of Europe.
